Spatial-temporal local binary pattern (STLBP) has been widely used in dynamic
texture recognition. STLBP often encounters the high-dimension problem as its
dimension increases exponentially, so that STLBP could only utilize a small
neighborhood. To tackle this problem, we propose a method for dynamic texture
recognition using PDV hashing and dictionary learning on multi-scale volume
local binary pattern (PHD-MVLBP). Instead of forming very high-dimensional LBP
histogram features, it first uses hash functions to map the pixel difference
vectors (PDVs) to binary …
