NettetSteps for Computing HOG: HOG is a technique for transforming an image to a histogram of gradients and later use the histograms to make a 1D matrix which would be used for training a model. Nettet26. jun. 2024 · The algorithm of HoG computation can be defined in five steps: (1) cell image normalization, (2) gradient computation, (3) orientation binding, (4) gradient histogram estimation, and (5) normalization across the blocks.

As Dalal and Triggs point out, however, this step can be omitted in HOG descriptor computation, as the ensuing descriptor normalization essentially achieves the same result. Image pre-processing thus provides little impact on performance. Instead, the first step of calculation is the computation of the gradient values.
