Research on Mars Surface Image Visual Feature Extraction Algorithm

Visual feature extraction was the basic of mars surface topography reconstruction. The deep research was done to extract mars surface image visual feature in the unstructured mars surface environment. On this basis, the paper gave the mars surface image visual feature extraction algorithm. The experimental results show that the algorithm has good adaptability to illumination change and rotation transformation of mars surface image. Meanwhile, the paper could extract the abundant visual features of mars surface image.
