One of the typical methods to extract the features of images is SIFT. SIFT has advantages of robustness in rotation, scale change and illumination change of the images. However, in matching by the original SIFT, there is a problem that the keypoints on edges often become false recognition. This paper therefore presents a method for decreasing this problem by apply Bilateral filter instead of Gaussian filter that is used for smoothing process in SIFT. Bilateral filter does not decide a weight by only using distances between pixels, but also considers brightness differences of pixels, and in the location where a large pixel difference is observed, it keeps edges by reducing the weight. By using this method , the amount of information of image differences increases and improvement of correspondence accuracy is expected. The experiments investigate different characteristics of our proposal to the original SIFT; differences of smoothed images, feature point extraction and SIFT features. In addition, they also verify performance improvement of our proposal in searching corresponding points. |
