content: Hi,I have a question about this topic. I want to process a image which have taken from mobile phone's camera. Actually, I have written "android" to subject but I can also use ios platform If I have chance.I am, now, using iphone phone and windows computer. Can I write and test any project with these equipments?If It is not possble, I have only one option, I will have to work with android platform.Thus, It doesn't matter any platform for me, I must take a photo and process it (taken photo must be process like just white and black and every black dots must be determined like vector)How can I do that and where should I start? (You can also suggest book to read to me because, I am really want to read a book which is about image processing)Best Regards,Karamel

content: Yes, you can process images with Android. There are several ways to do it: you can use the standard Android API's, which, depending on what kind of image processing you want to do (and the size of the image) may or may not give you enough performance.You can also use RenderScript, which is a framework on Android especially suitable to parallel data processing (e.g. image filtering), as it will automatically use the multiple cores and the GPU to process your image. Read more about it here:https://developer.android.com/guide/topics/renderscript/compute.htmlThere are examples that come with the Android SDK that will help you get started.If you don't need the performance, then the standard Android image API's will be fine:https://developer.android.com/guide/topics/graphics/2d-graphics.htmlGood luck! (and use Google!)

What the bullshit situation for me because, Sir. Mr. Fungus said thisisirrelevant thing about electronics engineering and unfortunately, he is exactly right.I am leaving my school

content: Hi,I got your idea, I had searched it on internet, after I asked.So, why I asked it?Because, I needed to direct correctly via mentor people. There are some solutions okay but, for example, mentors say that don't look at them or don't deal with them.Starting point is the most important thing.I think, you got me.

content: Hey, I use the program Altami studio, myself I use it with Windows and to be honest I haven't tried it on ios... but I know it is a cross-platform app, let me know if it works there as well

content: The OpenCV library is by far the most popular framework for image processing, and there is an android sdk.Starting point :https://opencv.org/platforms/android/A lot of standard image processing functions are implemented, and what you want to do should take only a few linesA good starting point could behttps://docs.opencv.org/3.3.1/d3/db4/tutorial_py_watershed.htmlfor the principles at least, of course you won't use the python api on android
