The invention relates to low power object detection hardware, a method, a computer readable medium and an apparatus. The low-power object detection hardware comprises: an array of hardware scan windows for storing pixel values or pixel block values based on two-dimensional sample windows of an image, configured to store pixel values or pixel block values based on different two-dimensional sample windows of the image at different times; computer vision feature calculation hardware configured to calculate one or more computer vision features based on one or more comparisons of pixel values or pixel block values stored in the hardware scan window array, wherein each of the one or more comparisons comprises a comparison between a value of a pixel or block of pixels and a value of another pixel or block of pixels within a two-dimensional sample window of the image; and a classifier configured to receive the one or more computer visual features calculated by the computer visual feature calculation hardware and dete
