Defines types and functions to handle the HOG operation.

HOG (Histogram of Oriented Gradients) extracts local gradient orientation histograms to capture shape/edge information for detection or description tasks. This operator computes per-pixel gradients, accumulates orientation histograms over spatial cells, normalizes them across overlapping blocks, and outputs the CHW formatted feature tensor from an RGB8p input image.
