WebTry to compare each descriptor from the first image with descriptors from the second one situated in a close vicinity (using the Euclidean distance). Thus, you assign a score to each descriptor from the first image based on the degree of similarity between it and the most similar neighbor descriptor from the second image. Web1 Jan 2024 · RootSIFT is an enhanced SIFT descriptor. SIFT has been the widely used technique for feature extraction due to its invariance to scale, rotation, illumination, viewpoint and translations. So the enhancement to SIFT to detect drowsy features has made an outcome more likely.
