Towards Understanding the Formation of Uniform Local Binary Patterns

Figure 21

Percentage share of runs level 2 permutations among images 1–4 in various permutation neighborhoods. The bar corresponding to uniform patterns indicates the occurrence frequency of runs level 2 patterns among uniform patterns only. It can be observed that the average frequency of runs level 2 permutations increases compared to the a priori model in all neighborhoods and even further when the uniform patterns are considered.
