Apps Android Image Processing

[stutech123]

I want to perform various image processing functions such as threshold,equalize etc on the image i capture from the camera...What should i use in order to do that?
Also,when i installed the app in my phone, after clicking the pic, the next screen appears, and after clicking the button for performing other functions, force close comes up...what could be the reason,because my code works fine without the camera portion...

We need to see both the Exception throwned in Logcat and the code that produces the exception

Well,I m not executing it using the emulator because I can't use the camera through that.so I don't know what exception is gettin thrown...
