Introduction to Histogram of Oriented Gradients (HOG)

NettetThe histogram of oriented gradients (HOG) is a feature descriptor used in computer vision and image processing for the purpose of object detection. The technique counts occurrences of gradient orientation in localized portions of an image. NettetStep1: In HOG, we divide the image into smaller cells. Step2: Compute histogram for each cell using the gradients and orientations of the pixels. Step3: Put these histograms together to create the feature vector, which creates a single, distinctive histogram for each face from all the little histograms. I have tested the code on sample images.

Short answer is: you can't apply Trilinear Inerpolation. Let's start with 2x2x2 blocks. Each block, is represented by it's centre pixel ( 1,2,3,4 in ugly yellow on my sketch). Each pixel is located at the corner of a cell. A pixel (the red dot), will be shared by up to 4 blocks that overlap.
