Image processing without deep learning or machine learning

Question

I am working on my graduation project and was wondering if there is a way to work on a disease detection project or an image processing project without deep learning or machine learning i have been looking for quite a long time but came with nothing.

Answer 1

Computer Vision and found some promising methods that I could use to find:

1. SIFT
2. SURF
3. Template Matching
4. Image Gradients
5. Canny Edge Detection
6. Histogram of Oriented Gradients
7. Hough Line Transform
8. Hough Circle Transform
9. Gabor Filters

I experimented with all the methods using Python OpenCV.
