The BM3D image denoising algorithm implemented in CUDA.

The dependencies are:

1. CUDA 7.5 (or newer)

2. Boost library

3. FreeImagePlus library (to read raw format input images)

4. OpenMP

5. chrono library for timing

after compiling, running command is:

./binary "image file name" "format" "input directory" "out directory"

The input images can be png files or raw input images from various cameras such as .cr2 , .arw, .nef , .rw2, .sr2 (any input format that FreeImagePlus can read). The implementation uses tiling for high resolution images to fit the GPU memory and shared memory.
