Sift algorithmus
WebScale-invariant feature transform (SIFT) is a broadly adopted feature extraction method in image classification tasks. The feature is invariant to scale and orientation of images and robust to illumination fluctuations, noise, partial occlusion, and minor viewpoint changes in the images. These characteristics are important for mitosis detection ... WebSep 10, 2024 · 1. SIFT feature is a local feature of image. It keeps invariant to rotation, scale scaling, brightness change and stable to a certain extent to view angle change, affine transformation and noise. 2. Distinctiveness is good and abundant in information.
