WebBased on this study, new approach (Volume-SIFT) to remove unreliable keypoints detected by SIFT algorithm is proposed. Furthermore, to keep keypoints detected at large scale and near face boundaries, we propose Partial-Descriptor-SIFT (PDSIFT) approach. Comparisons between feature based ap-proaches and holistic approaches are also given. We ... WebScale-Invariant Feature Transform (SIFT) SIFT is a computer vision algorithm to extract features from an image. Extracted features from multiple images can be compared, and the same feature on all images can be extracted. Applications for this algorithm include object recognition, image stitching, gesture recognition as well as photogrammetry.
