Embodiments described herein provide a system and method for generating a binary descriptor representing an image patch (). The method includes determining a first specified number of features within an image patch (), performing mean intensity difference tests for the first specified number of features, and generating a binary string of the first specified number of features for the image patch () based on the mean intensity difference tests. The method includes dividing the image patch () into a number of sub-patches (), and, for each sub-patch (), determining a second specified number of features within the sub-patch (), performing mean intensity difference tests for the second specified number of features, and generating a binary string of the second specified number of features. The method also includes transforming the binary strings for the image patch () and the sub-patches () into a binary descriptor representing the image patch ().
