Abstract
This paper presents a novel method of determining the overlapping area in advance to accelerate the SIFT (Scale Invariant Feature Transformation) algorithm. The SIFT algorithm can achieve high accuracy in image matching, however, it can be time-consuming when processing large images. The proposed method in this paper pre-selects the overlapping area of input images to speed up the feature extraction of SIFT. This improvement of SIFT can greatly reduce the processing time without affecting the accuracy.
