تغییرات جدید الگوی دودویی محلی و طبقه بندی و قسمت بندی تصاویر بافتی بستر دریا

Texture analysis plays an important role in image processing. Considering the extraordinary appearance texture sonar images, texture analysis are good choices for analysis of acoustic seabed images. Local binary pattern (LBP) operator is a very efficient and multi-resolution texture descriptor. It acquires appropriate information from the illumination and moods of images. Despite many developing of the LBP have proposed, but they are sensitive to noise. Also sometimes they lead to describe different structural patterns with same binary codes, which would reduce their ability to differentiate. This paper proposes an overview in provided LBP methods which includes several of the newer ones. Then it proposes a robust framework of binary pattern as completed robust LBP to overcome the inefficiency of all types of LBP which the value of the central pixel replace whit average value of intensity values of 3*3 square adjacent. Proposed approach is a quick tool with high accuracy in the classification of the seabed images. The comparison of simulation results with other known methods indicates the effectiveness of the proposed algorithm.
