Class Summary Class Description BaseDenseHog<I extends ImageBase<I>>Base calss for dense HOG implementations. DescribeDenseHogAlg<Input extends ImageBase<Input>>Implementation of the Histogram of Oriented Gradients (HOG)  dense feature descriptor. DescribeDenseHogFastAlg<Input extends ImageBase<Input>>A variant on the original Histogram of Oriented Gradients (HOG)  in which spatial Gaussian weighting has been omitted, allowing for cell histograms to be computed only once. DescribeDenseHogFastAlg.Cell DescribeDenseSiftAlg<D extends ImageGray<D>>Computes
SIFTfeatures in a regular grid across an entire image at a single scale and orientation.
