Robustness to photometric transformations and invariance under geometric transformations are two crucial criteria that a shape descriptor must satisfy. In this direction, orthogonal moments have proved their performance since the image can be reconstructed from its descriptor. However, these conventional moments deal only with binary and gray-level images. Recently, the algebra of quaternions have been widely used in combination with these moments in order to describe color images. In this… CONTINUE READING
