HIGHLIGHTS
- who: Wannan Zhang from the SchoolSouth University have published the article: An improved SIFT algorithm for registration between SAR and optical images, in the Journal: Scientific Reports Scientific Reports of 23/01/2023
- what: The aim of feature extraction stage is to obtain a sufficient number of relevant point features uniformly distributed in the image and scale space, while the block strategy obtains uniform point features in the whole space by extracting the feature points of each regular grid. The authors propose an improved SIFT algorithm for optical and SAR image registration.
