Sift algorithm in image processing
WebThis study suggests two methods for using image processing; the Scale Invariant Feature Transform(SIFT) algorithm and Optical Character Recognition(OCR). The first method which works with SIFT uses image feature points. Through feature matching, it can be applied to calculate the similarity between documents containing these images. WebMar 20, 2024 · With the increasing applications of image processing in solving real-world problem, there is a need to identify and implement effective image matching protocols. In …
