SIFT is known as local features that has robustness against rotation, scale and illumination changes of the images. However, in matching by the original SIFT, there is a problem that the keypoints on edges often become false recognition. We had therefore presented a method for alleviating 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 only by 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. However, there is a problem from the viewpoint of computational complexity. Therefore, we try to develop faster implementation of the proposal by using GPGPU. We accelerated the filtering process by CUDA which causes heavy increase in computation time, and confirm its faster processing. |
