Abstract: When directly applied on images with different scales, SIFT matching performance decreases significantly. In this letter, this phenomenon is demonstrated and a simple method to increase the performance of SIFT matching is proposed. The proposed method includes preprocessing the images before matching and is compared to the previously proposed solutions which only eliminate the false matches.
Bastanlar et al. REF proposed the Improved SIFT matching to increase the number of accurate matches while removing the false matches.
