SRP. (a) Represents pixel value in 1st Square ring (S) at j th position. (b) Pixel values and differences are extracted in five different patterns from image patch size of \(5 \times 5\) pixels followed by computation of local sorted descriptors (\({x}^{Glob}\), \({x}^{Sqr}\), \({x}^{Circ}\), \(\Delta ^{Ang}\) and \(\Delta ^{Rad}\)) using Eq. (7). Feature functions (\(f_{S}\), \(f_{G}\), \(f_{C}\), \(f_{A}\) and \(f_{R}\)) are obtained and horizontally concatenated to build SRP feature descriptor. (c) Proposed 3D SRP approach.
