I am planning to make a Android App that uses 2D Haar Wavelet Transform to encode data into pictures. Can OpenCV do the transform for me? I am new to OpenCV and am seeking a java library that is able to do this.

Yes, the haarwavelet structure are actualy simple 2D filters. Filtering is implemented in OpenCV. Just look for the correct filter structure to get the desired result.

I only know the C++ - code but you can use Java bindings to reach the same result.

Just give filter2D a try, but looks like it can not implement the haar discrete wavelet transform.However, stack overflow do have an answer
