Abstract :
Scale Invariant Feature Transform (SIFT) is an effective algorithm in feature detection and scene matching. In this paper, we proposed an improved Scale Invariant Feature Transform (SIFT) based on D2OG keypoints detector for better real time performance and explored the performance of 64D, 96D and 128D SITF feature descriptors on standard test datasets. Results shows that the improved Scale Invariant Feature Transform has a big progress in the real time performance and the 64D, 96D SIFT feature descriptors performs as well as the traditional 128D SIFT feature descriptor for image matching at a significantly reduced computational cost.
