I am looking for the way to get related images like Pinterest search. I have searched a lot. Most of the solution is to compare image pixel by pixel something like this. What I want is to compare the image if comparing result is more than 75% I want to show the images.
Is there any algorithm or image processing library available for Android to achieve this?
Please help to solve this. Any help would be appreciated.

I am beginner in android. I am working on porting ffmpeg to android and i am able to display the picture, which looks really odd. I am providiing the links to pictures please advice me what really went wrong in my case.
In the native code I call sws_scale function to convert image from native format to rgb 565 and I use this rgb565 frame to be displayed using canvas and bitmap in java code.
I am guessing this is interlacing problem, but not sure. Need suggestions . Please help.
How are you calling ffmpeg? I definitely agree that its an interlacing issue. Can you just pass deinterlace to it?
Long time reader never posted until now.
Im having some trouble with Android, im implementing a library called JJIL its an open source imaging library.
My problem is this i need to run some analysis on an image and to do
so i need to have it in jjil.core.image format and once those
processes are complete i need to convert the changed image from
jjil.core.image to java.awt.image.
I cant seem to find a method of doing this does anyone have any ideas
or have any experience with this?
I would be grateful of any help.

You should let others know what you found... probably you found that android.graphics.Bitmap has a getPixel(x,y) method that returns an int representing the ARGB value?
http://developer.android.com/reference/android/graphics/Bitmap.html
I have done some serious research into this and i have found that i can extract the rgb values of a bitmap image with a similar method.
But the threshold that i was using the previous library for is now not possible because i have had to abandon the use of this library.
Is there a way to use colour matrix's to threshold the image? Or better still is there an inbuilt method that would do this automatically?
Thank you for any help.
