WebJan 1, 2024 · Therefore, affine invariant feature extraction is avaluable technology in the field of image recognition. Inspired by bio-visualmechanism, an affine invariant for object recognition method based on a fusionfeature framework is proposed in this study, which employs geometry descriptorand double biologically inspired transformation (DBIT). WebEven though this notion is intriguing in its simplicity, little is known about affine invariant points. At the same time, these are fundamental invariants of convex sets. They are, for instance, useful to characterize properties of symmetry or of non-symmetry of convex bodies (e.g., [13] and [14]). le chat chinchilla
