Witryna15 mar 2024 · Two new encoding schemes for representation of the intensity function in a local neighborhood are presented, which are complementary to the standard local binary patterns (LBPs) and preserve an important property of the LBP, the invariance to monotonic transformations of theintensity. Expand Witryna25 mar 2011 · Histograms of Local Binary Patterns (LBPs) and variations thereof are a popular local visual descriptor for face recognition. So far, most variations of LBP are designed by hand or are learned with non-supervised methods. In this work we propose a simple method to learn discriminative LBPs in a supervised manner. The method …
