Abstract :
Due to the invariance to scale and rotation, image matching method based on Log-Polar transformation has been extensively applied in target detection and location. This paper analyses the effect on image matching accuracy from variation of scale and rotation, and proposes a modified image matching method based on analysis of data reliability for matching, this method can eliminate the interference from invalid data and improve the image matching performance. Experiments show that this method has better performance in accuracy.
