I'm an undergraduate student and I am currently trying to find suitable topic for my bachelor thesis. The broader topic I've selected is "Image processing on GPU", so basically I'll be developing image processing algorithms specifically for GPU.
The problem is, I need to do a novel approach, not reinvent a wheel. There's so much going on in image processing, lately on GPUs as well, that I'm having trouble finding a suitable area that hasn't been researched in this way and which isn't above my capabilities as an undergraduate.
The question is, can you point me in a direction what are current research areas in image processing that could benefit from GPU implementation? I'd love to do something for medical or astrophysical applications, but I'm open to other areas as well.
