Abstract:Based on the local binary patterns, a new improved method for extract local texture is introduced, namely local ternary patterns. This extraction method can be used to remove the shadow of movement. The background is modeled with adaptive gaussian mixture models, to get the background and foreground object. Then the intensity property is used to obtain the probable-shadow blocks. The shadow detected is improved based on the similarity of texture represented by LTP between shadow region and corresponding region in the background. Finally, the shadow can be removed accurately. The experimental results show that the algorithm can inhibit partition noise, and accurately remove the shadow of the movement.
