An effective image shape feature detection and description method

To solve the problems of complexity and low robustness that exist in present image shape feature detection and description methods, a new image shape feature detection and description method is proposed. First, salient regions are detected using a method based on connected component. Then, a descriptor composed of Hu's moment invariants and eccentricity is used to descript the detected regions. Experiments show its effectiveness and robustness to translation, rotation and scaling.
