• Intensity permutation
• local image descriptor
• zone division

Image representation through local descriptors is a research hotspot in computer vision. In this letter, we propose a novel local image descriptor based on intensity permutation and zone division. The oFAST detector is first employed to detect keypoints with orientations, and then steered patterns are applied to sample rotation-invariant points within the local keypoint patch. In the step of local patch description, intensity permutation and zone division are implemented to construct our descriptor, with the advantages of inherent robustness and invariance tomonotonic brightness changes. Our proposed algorithm performed well in the experiments on benchmark dataset for descriptor evaluation.
