[APP] Motion detector with recording abilities

Hello everyone,
I am new to this forum. I decided to register here after I completed my android project.
I created a program that can detect movements and save pictures of the moving objects. Phone has to remain static in order to work properly. The program also features separate address book. Address book keeps phone numbers for SMS notification. In order to activate that you have to create a new contact then long press the item in the list. The program creates folder on memory card where it saves the pictures. The speed is very high on Galaxy S. You can throw something fast and phone still snaps the flying object if it passes by the camera.
The program has many settings that can dramatically alter the performance. Settings have to be adjusted in accordance with the lighting conditions.
I tested app only on 2.2 Vibrant. I am really curious to see how it works on other 2.2 devices.
ARMv7 processor is a must!!
Please give me some feedback!
App is called Motion Recorder

this sounds like a great app. gonna try it now on my incredible.

My app MobileWebCam also does this (simpler detection algorithm I suppose) and can automatically save, upload the pictures or send email:
Development Thread is here:
http://forum.xda-developers.com/showthread.php?t=950933
Are you interested in sharing your motion detection code? Possibly we could combine functionality of both apps?

dirtsky, If you have any questions or if you find any bugs please write in this thread.
The program is little hard to use so feel free to ask.
_miha_, Mine detects motion by analyzing color. What about yours?
How do you send e-mail without the annoying pop up?

My motion detection is three steps: Image is converted to grey, then I max every pixel with the ones around to remove the flickering pixels (especially needed for night/low contrast situations) and calc the difference between the last and this new pixels. Some magic value (which should better be configurable later decides about the motion. Problem is this is very slow (should use the ndk but only began working with it recently) so I have to scale down the image before which is bad for small/distant moving objects.
Email: Is not sent with Android/Intent. I use JavaMail. I had some difficulties with the libs but got it working somehow (and even more difficulties with proguard which I needed because file size is getting too large without using it).

_miha_, did you test my app? How does it stack up against yours in terms of performance?

I cant seem to find where the images are being saved on my SDcard. Epic 4G Froyo ec05 midNight Rom
I looked for the folder "Motion Recorder" and i dont see it. and theres nothing in the Gallery

zman519, since your device is basically Galaxy S type it will save in internal memory(aka 14 GB "SD card").
Please let me know if you find the folder there.

I have total 105 installs out which 35 are active. Is it considered as bad result?

UPDATE: 59 active installs out of 109 which makes it >50%. Is it good?

The Epic does not have an internal sdcard. That must be the problem. I looked around with root explorer and did not see the folder.
Sent from the Drivers Seat of my Suby txting and Driving doing 100MPH+ in a school zone! Ha.

zman519, thank you for feedback, I will fix that and let you know once the update is ready. It should not take more than half an hour.

Question to developers:
My program saves pictures to the following path:
String path = "/sdcard/Motion Recorder/TakenOn" +...
Why does it not automatically save to external sd card in the case when there is no internal sd?
UPDATE. I figured out myself. Working on update that allows user to choose between internal and external memory.

Hello dev,
I tried it on my DHD - it crashes and don't save settings.

I just updated to v0.42 which adds support for the external storage. Just go to settings and tap the checkbox. Unfortunately I have not tested the new feature on the actual hardware because I do not have one at the moment. So please, those of you who can test it please let me know if it does not work.
drast-x, Thank you for the feedback. Please give me some more details. When does it crash? After you hit the start? When you hit the start do you get the preview from the camera? Unfortunately settings do not save after the exit except contacts...
Did it happen on:Jun 11, 2011 9:32:07 PM ? I ask you this because Developer console shows me one crash that occurred at that time:
java.lang.RuntimeException: Fail to connect to camera service
at android.hardware.Camera.native_setup(Native Method)
at android.hardware.Camera.<init>(Camera.java:294)
at android.hardware.Camera.open(Camera.java:271)

Does saving pictures work on any of the phones except Epic 4g?
Thank you

I updated to v0.45
Now settings will save. Motion Recorder 0.45

Many thanks to the user of my app who sent this feedback:
"force close when start button clicked in nexus".
It turns out Nexus One (or S?) does not support either VGA or QVGA preview frames. So I had to fix this issue by requesting the supported resolutions. Very surprised by this issue. I expected that Android OS would figure this out on its own...
Thus new version 0.45.5 is supposed to fix the issue. I do not have Nexus One so I am not 100% about the fix. Those of you who are reading this and have Nexus One, please try new version!
Thank you!

Have you tried first reducing your image resolution to something ridiculously small like 32x32 and apply a DCT to keep only the low frequencies?
This might offer much better performance.
You can perform very good

[Q] Spreadtrum GT-A7100 Camera Issue

Hi,
This is my first post over here, so please forgive me if I make any mistakes..
In January I bought my first Android phone, a Spreadtrum GT-A7100 (SP6820A). It's not as bad as I thought, but I have noticed several issues with it recently.
Although the phone specifications, as well as Antutu and other system checking apps, reveal that the device has a 3.1MP camera, the photos taken using it are of very low (often VGA) quality. Also the flashlight does not sync with the shutter, so I can't take any photos in the dark. (While the images have the required resolution, 2048*1536, they are all blurred and sometimes not even recognizable.)
I tried several stock camera apks from http://forum.xda-developers.com/showthread.php?t=1333387, but none worked. (The system simply fails to recognize the new camera app when copied to /system/app. I tried 'installing' the apps, but they don't get installed.) No ODEX file was found in /system/app, so I suppose it can't be an odex problem.
I also tried to find a stock ROM, but it seems that none are available on the internet for this device. (http://forum.xda-developers.com/showthread.php?t=2149396 has a ROM for GT-A7100 with chipset mt6515_c910_ht_en_4.0_v01, but mine is mt6515_c910_ht_en_v05; the author discourages flashing the ROM on devices other than those with the given chipset.)
I'm a newbie to the Android world; can someone help me get started on fixing this issue?
Thanks!
(There's a whole lot of more issues; I'll come to them later.. )

[Q] Good mobile phone cameras

I'm a photographer who wants to get good quality images when they have to be shot with a mobile phone (maybe because it's the only camera I have with me at the time). The camera isn't the most important thing I consider when selecting a phone, but it's still important.
Megapixels are not that important to me - even if I was to display my images on a 1000 x 1000 display screen, that image would have only 1000 x 1000 = 1000000 pixels..... 1 megapixels. Unless I want to print or crop my photos, I might as well use a 1 megapixel camera. Bottom line for me, 4 or 5 megapixels is more than I need.
The quality of an image depends on many more things, the quality of the lens, the camera sensor, the ability of the camera-phone to focus properly, the software that determines the camera settings (ISO speed, shutter speed, f/stop), and the software that processes the image that has been captured, creating the image file that gets stored on the phone. (I realize a lot of the above is not too important to most people - they just want to capture a snapshot, possibly apply filters to the photo to give it a different look, and send it to friends or social networking sites. Fortunately, there are lots of "apps" that do this very nicely.) What I'm concerned with, is the quality of the captured image, not how it might be modifed.
My question here, is to ask what is the best way to do threethings:
First, to take control of the camera, and adjust the settings manually (ISO speed, shutter speed, lens aperture, focusing distance).
Second, to save the image to a file as an un-compressed file, even if this makes the file size very large, and
If possible, to save the image data, in "raw" format, so that all the information from the camera sensor is saved in a file.
It is unlikely that a mobile phone can process an image as well as a dedicated computer. Anyone who has ever worked with "raw" images knows how much hidden detail is included in those files, much of which is lost as soon as the files are saved as "jpg" images. I'd like to be able to do that, but maybe it's too much to ask for - for that to happen, the camera would need to save the "raw" file, and the camera manufacturer would need to release the information on how a computer program could "read" that data.
I've been doing some of the above, using the app "Camera FV-5". On my HTC One Google Edition, it seems to help get images that might be as good as what the phone hardware allows. What I would really like though, is a way to capture ALL the data from the camera sensor as a photo is taken, transfer it to my computer, and use a program such as Lightroom or Photoshop to transform that "raw" data into the best image possible from the captured data. I know this isn't possible using the standard camera functions, but I was thinking that maybe I could somehow get the camera data by using some "development" features.
Any suggestions?

[Q] Issues with .RAW Camera Setting in SlimKat Unofficial 2.3

Sorry if this should go in the SlimKat forum, but I figured it is a 4.4 issue, possibly not specific to SlimKat.
I was messing with my camera settings the other day taking some photos, and I came across the option to change from .jpeg to .raw. I changed to .raw hoping to review later and see if I could improve the photos. I took several photos in .raw format, but now I cannot view them. At first they appeared as just gray boxes in the photo gallery (which was my first clue), and then I thought i would just transfer them to my computer and i would view/process them there.
However, I am completely unable to view these photos. I have installed RawDroid on my phone, but it will not view the files (actual or thumbnail). I have also tried several different programs on my Windows 7 PC (File Explorer, Corel Paintshop 6, Paint Shop Pro, and even Irfanview) - none of them will display the photos. I know there is data there - each file is about 10.2MB in size; I just can't get them to display no matter what I try. I am extremely disappointed because there are at least 4 of the files that I would really like to keep.
Any ideas on how I can get the photos to display? I have searched Google and the forums here to no avail. I cannot seem to find anyone or an article on this particular issue.
And, as I said, my apologies if this should go in the SlimKat forum - Mods, please move if necessary.

HELP: Losing EXIF on Edited Files?!?

Hi guys,
I use the Z5 for a lot of photos and some of the edits I do it on the camera itself because the app is powerful enough - I use the Built-In Photo editor instead of the Google Photos.
I am facing two issues and I was wondering if there is any solution under Android 5.0 or if the newly released update could solve any of the issues below:
- Edited photos as saved under Local Storage as opposed to SD Card, where original photos are saved. Not so bad but I need to move them periodically back to SD Card. Not sure why this happens because I am using all native photo apps (Sony Camera + Album + Photo Editor)
- Big Issue: edited photos completely lose EXIF info, like time taken and camera info. Big time problem for photographers. What is going on here?
Any help would be greatly appreciated!
PS. The phone runs extremely well and stable, so I was NOT planning to update to 6.0 for the fun of it, but I need a solution for the issues below.

Any one else facing this issue with the EXIF file?
This morning I updated to Android 6.0 via Sony PC Companion 2.1 and tried editing a photo and same issue with saved file losing EXIF data. This is a bit ironic coming from a phone marketed as a Camera phone.
Any help regarding this would be greatly appreciated!
Thanks
