Using Python and openCV to create a difference of Gaussian filter

SIFT SIFT (Scale Invariant Feature Transform) is one of the underlying concepts in Structure from Motion photogrammetry, which plays a large part in my Masters research. To better understand how the process works I am working through the process manually, calculating all of the intermediate steps along the way. The first (of 4) phases of… Read more »
