Nettetthat if the image of the person is significantly smaller than that then resolution might be insufficient to detect it reliably, so it is not even worth trying. The person could of course occupy a bigger part of the image. Because of this, one analyzes not only the original image, but also those in a pyramid of images: A 128 by The 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. This method is similar to that of edge orientation histograms, scale-invariant feature transform descriptors, and shape contexts, but differs in that it is computed on a dense grid of uniformly spaced cells and uses overlapping local contr…
