Number Local binary pattern: An Extended Local Binary Pattern

An extension of local binary pattern, named Number Local binary pattern (NLBP), is presented for texture analysis. First, the method divides the patterns into uniform and non-uniform according to the uniform measure. Second, the non-uniform pattern is further divided into different groups based on the numbers of `1´ bits and `0´ bits. The experiment shows that NLBP achieves a good texture discrimination compared with the state of the art methods such as Uniform Local Binary Pattern (ULBP) and Extended Local Binary Pattern (ELBP).
