[Q] App Development Help

Thanks for the help!

Hi,
I am trying to develop an app, with little experience of WP7, on Visual Studio Ultimate 2010, in C#. The app I am trying to develop needs to be able to take your pulse using the flash of the camera to illuminate your finger and then detect the changes in brightness to calculate it. To do this, would I be better off recording a video for like ten seconds in the background (the UI will just be text that says place your finger over the lens) or would I need to use a while loop and have it take a picture like every 40 milliseconds then have will flip through the pictures and see how often a dark spot comes up or something? Any code examples or links would be greatly appreciated. Thanks!

Well, I didn't caught the idea of the app you want to develop, but if I understood you right and you want to measure pulse by taking photos/videos of a finger, it looks like some kind of science fiction. Just imagine the accuracy needed for such calculations and how will you keep you finger still.
Talking about video: if I am not mistaken all the currently existing background agents are restricted to use Camera API, may be I'm a bit wrong here.
For learning C# for Windows Phone 7 it is good to begin from MSDN and bunch of code samples stored there or a book.
Best regards.

This is actually already being done on other smartphone platforms; hell, people are using smartphone sensors for all kinds of crazy things, including a number of medical applications.
Given that the highest pulse you're ever likely to encounter is about 240 BPM / 4Hz (250ms between beats), 40ms resolution seems more than needed. That said, that's only 25 FPS, while I believe the video camera shots at 30 FPS (33ms). However, taking pictures probably won't work so well because of the need to JPEG-compress the images after taking them (I think the camera API *always* does this, though I might be wrong). Using the video stream API seems like a much better idea.
You shouldn't need the background APIs at all; not sure why the guy above me talked about them. My understanding is that these apps just sample for a few seconds, enough to get an accurate reading.
You may get better info in the App Development sub-section of the WP7 D&H forum. That said, don't expect people to write your code for you, especially for something where there's a reasonable chance of it being a commercially viable Marketplace app. I suggest you start with MSDN, but reading the docs and looking at the examples. You can also go look up tutorials and example code online for using the video APIs.

【APP】【1.1+】【Limit free】【photo】Instant ID Photo

【APP】【1.1+】【Limit free】【photo】Instant ID Photo
HI，all
Sorry for bothering you. This is Lulu Wang, from Leqi Technology Co.,Ltd. of China.
Please allow me to introduce our APP, Instant ID Photo, a camera application which can help users to DIY their ID photos for passport, driving license, visa etc., easier, smarter and more beautiful. Now It is just available on App Store, (download promotion code: REER6EA4WTJA). We wish you could evaluate our APP to make more users know it and make it help more users.
Compared with other similar apps, our app has the following prominent characteristics deserved to be reported:
• Intellgient background/foreground segmentation using advanced deep learning technologyInstant ID photo utilizes our excellent intelligent face/hair/head/shoulder segmentation technology, which can automatically segment out the user head-shoulder part pretty well even under complex background. So the users can seamlessly replace original photo background with any color they wanted without applying any complex PS steps.
• Smart cropping
Instant ID Photo has provided almost all sizes of commly used ID photos. Users do not need to check the specifications of ID photo and crop the photo size manually. Only by one shot, our app can crop size as your wish automatically.
• Natural beautification
The embeded face beautification engine can automatically analyze the face/image information such as the age, gender, ethnicity, illumination condition etc, and make the ID photos look as nice as users really are. Of course users also can manually enlarge eyes, shrink mouth, remove the speckles, brighten skin tone etc as they wish.

Please don't create multiple threads. Use your original one and just update the OP of it.

[APP][FREE][BETA][5.+] PixelCam - Record videos with awesome effects

Hi guys!
Pixelcam is an app that allows you to apply awesome effects to your camera directly while filming or taking pictures.
I started working on this a long time ago and gave up a few times because the android Camera APIs are such a pain in the ass for developers (for me at-least).
The idea came from when I was testing out stuff in libgdx and found out about the things shaders could do in opengl.
I've been babysitting this project for too long. With the latest news from google and prisma, there is one thing left for me to do, just release it and handle the feedback like a man.
PixelCam is an app that applies effects to your camera, it allows you to record video/take pictures with opengl shaders applied directly to the output, so no post-processing is needed and the possibilities are truly endless (Or so I like to think)
I have been able to test on oneplus, samsung and huawei devices, so all crash and glitch reports are welcome, it's the only way I can fix issues and make this app better! Please give it to me raw & uncut.
The app is totally free and has no ads.
ps. the fact that it's the worst named app at this moment is just bad timing I should have released it much earlier

Thank you in advance

Sounds good

Question Photosphere - impossible so far on S22

I can't believe that making a photosphere in this day and age is impossible on the S22 Ultra.
I've not been able to create one with any software so far that I've tried. Google Street view for instance is useless because it doesn't have the ability to figure out the focal length of the lens so the stitching is a complete mess.
Does anyone know of a solution? Or am I wasting my time.
If not does anyone know of an assist app that will provide the guides (like) Google street view but save the individual pictures so I can use stitching on the PC?

Samsung used to have a camera plugin that allowed you to capture several images and stich them together. I could do it on my S8+ and Note 8. It was a little clunky, but it produced decent results.
Samsung stopped supporting it after the Note/S 9 series because I couldn't do it on my Note 10+. It wasn't a widely used feature.
Here are some PC and Mac apps that can do 3D image stitching. Not all are free.

Hi Gernerttl,
Thanks for your reply.
Yes I had this feature on my Note 4 which did deal with spherical panoramas (or photospheres ) and it did a great job.
As I say the problem with apps that do this now fail on some smartphones due to the focal length of the lenses and the ineptitude of the software in failing to find out what that fl is.
So whilst Google and other software are good at guiding you in covering the whole sphere the stitching is poor and sadly they are so basic that they don't make the separate photos available so you can export them.
The link you gave is for stitching software and that isn't the problem for me.
Ideally I'd like to find software that would work on the phone but if not I'd like to find software that would provide the guiding process of covering the sphere and save the separate tiles so I can then put them into the stitching software.

Yes I was working off that list actually as searches are so limited this is about the only thing that comes up.
Google view and one of the others proved exactly the same - Google obviously implemented that companies version into their street view.
One is for IOS only and I have not tried (but will) the last two even though they appear to have less regard for settings. I'll look at some of the Android stitchers too in case some offer the assist to take the photos. Most expect you to already have taken them with adequate overlaps but as you can imagine doing a whole sphere and making sure you are tracking what you have covered so far is a pain.
Thanks for the help I will try the offerings here but unless they photosphere offerings allow you to change camera lens FL they will assume a standard lens and fail. I'm surprised developers did not think of this as it's a complex process and I would have thought it'd have been essential.

You're welcome. I'm not sure it'll get fixed anytime soon. Not until OEMs figure out how to make a camera module that can implement an optical zoom with ultra-wide to super-telephoto focal lengths using one lens.

Hehe, well finally I've worked my way through all the pathetic offerings. All the apps are kiddy type apps which have no complexity whatsoever, most just do circular panos and the stitchers were even worse refusing to deal with anything but circular panos.
Sadly disappointing.
I think the only solution is to get a 360 standalone camera, these do video which I'm not interested in, so expensive and the quality isn't up to the camera on the S22 Ultra. [sigh 2023 - that's what we get - LOL)

Gcam has a photosphere plug in, I've just tried it seems ok, but maybe you've already tried?

No, I had a link to a table of models and versions (somewhere) and when I checked there wasn't a gcam version for the S22 range.
Can you tell me which one you installed?
My version is also with Exynos chip if that matters.

Not sure if I can link it but Google gcam s22 ultra and its the getdroidtips link but I've just checked and I'm using snapdragon model.

OK, thanks

You can capture (for now) 360° photos with Street View app from Google.

As per my first post. Done that - it fails to stitch properly.

Unfortunately 360 image capture has, for the most part, gone back to being a niche genre. The Samsung 360 camera plugin worked pretty well. Then Samsung dropped support for it when it decided to market and produce a 360 camera. Unfortunately, Samsung's foray into producing 360 image capture didn't last that long. Because the market is small, it was already saturated with devices made by Ricoh, Go Pro, Insta360, etc.

Thank you . Will give that a try.
I actually tried Google view outside and it failed on top and bottom stitching unlike when I tried it indoors where it failed to stitch almost everything.
Hopefully this will be better.!!

Yeah, I recently got fired up because I bought a DJI mini 3 pro and the spherical panos on that are superb.
Got to thinking about them again and having access to panos on the ground.
Which makes me also wonder about the viewer.
Gallery on my S23 works fine if the meta shows a pano. I get a 360 photo button when it's recognised and it will display with several options.
I sent this to my friend and he has the S20 and his Gallery doesn't seem to support pano viewing at all.
Found that strange since I had the viewer on my Note 4 many years ago and the S20 isn't very old at all.
Oh well.
