Sift descriptor matching
WebApr 16, 2024 · Step 1: Identifying keypoints from an image (using SIFT) A SIFT will take in an image and output a descriptor specific to the image that can be used to compare this image with other images. Given an image, it will identify keypoints in the image (areas of varying sizes in the image) that it thinks are interesting. WebHere the SIFT local descriptor was used to classify coin images against a dataset of 350 images of three different coin types with an average classification rate of 84.24 %. The …
