The Moment Invariants and Its Appliance of Image Retrieval Based on Shape Features
Zirui Zhang · Journal of Changchun University of Science and Technology · 2009
The method of generating trigonometric function is suggested as a new efficient way to derive various moment invariants,and it describes an extraction method of global shape feature of image based on Hu moment invariant and the correlative algorithm. The experimental results illuminate that the shape features extracted by this approach is,rotation and scaling to be which is translation rotation and soale invariance.
