SURF (Speeded Up Robust Features), is a feature detector, we talked about SIFT before, and SURF is sort of derivative of SIFT. SURF is based on sums of 2D Haar wavelet responses and makes an efficient use of integral images. I’ll not represent the whole story of SURF, because its idea is very similar to SIFT, so […]

I’m working on a project which is something like Bundler with my team, our aim is using different images of an object (we only have images, and know nothing about the positions these images took or parameters of cameras), to re-construct the 3-D module of the object. In this project, I used RANSAC on calculating homographies […]
