Efficient rotation‐invariant histogram of oriented gradient descriptors for car detection in satellite images

Cars can appear at any orientations in satellite images, but the widely used traditional histogram of oriented gradient (HOG) features is not rotation‐invariant. Recently, a rotation‐invariant HOG descriptor using Fourier analysis in polar coordinators has been proposed and has shown good performanc...
