A descriptor is a vector of values, which somehow describes the image patch around an interest point. It could be as simple as the raw pixel values, or it could be more complicated, such as a histogram of gradient orientations.

WebOct 27, 2024 · The dominant approach for learning local patch descriptors relies on small image regions whose scale must be properly estimated a priori by a keypoint detector. In other words, if two patches are not in correspondence, their descriptors will not match. A strategy often used to alleviate this problem is to “pool” the pixel-wise features over log … WebIn this paper, a novel benchmark is introduced for evaluating local image descriptors. We demonstrate limitations of the commonly used datasets and evaluation protocols, that lead to ambiguities and contradictory results in the literature. Furthermore, these benchmarks are nearly saturated due to the recent improvements in local descriptors obtained by learning …

The neighborhood of a pixel is given in the form of P number of neighbors within a radius of R. It is a very powerful descriptor that detects all the possible edges in the image. The proposed work used P = 8 and R = 1 with uniform LBP ( Eq. 13.12 ).
