I am too ambitious last week. I was planning to implement HOG on GPU, but now I am still trying to upload image to device and compute gradient image which is used for compute HOG. Still not familiar with CUDA APIs, though we have done homework2 for practice. I just had two mid-exams this week. Now I can concentrate on the final project. Overall, I just made little progress last week. I need to catch up and get well prepared for next week's presentation.
