Netteton the level of detail. For instance, the blurring that results from the pyramid computation removes some of the grain caused by the splash of mud in Figure 1. That grain would confuse the HOG detector at ﬁner scales. Practical Aspects: Variants of HOG. The description above is one interpretation of the original paper [1] on HOG. The first step of calculation in many feature detectors in image pre-processing is to ensure normalized color and gamma values. 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.
