Gauss-Laguerre keypoints descriptors for color images
Andrey Serdjevich Krylov, Dmitry V. Sorokin · 2011
Keypoints descriptors construction algorithm for color images is introduced. The algorithm is based on multiscale Gauss-Laguerre circular harmonic functions expansions of each image color component. The color components are obtained from color invariance model derived from Kubelka-Munk photometric reflectance theory. The matching results of proposed algorithm confirm the importance of color information for keypoints descriptors construction.
