SURF Features A frequent approach to feature extraction from images is SURF (Speeded Up Robust Features) Codebook You can use the function create_codebook.m to create a codebook with k-means Histograms Write a function that creates histograms of single images by assigning the image features to clusters from the codebook and counting their frequency Object recognition Choose two distinct subsets from the images. Create a codebook from one set
