Extracting spatial arrangement of structural textures using projection information

摘要

A new algorithm is proposed which extracts the spatial arrangement information of texture elements in structural textures. In the proposed algorithm, using projection information in several directions obtained from the texture image, two directions which determine the texture structure and parallelogram grid which isolates texture elements are extracted accurately. The isolated texture elements are analyzed and used to synthesize a texture image. Computer simulation shows that the proposed method can extract the correct spatial structure of the structural texture even when the texture image is highly corrupted by additive noise. Furthermore, the selected spatial arrangement information is shown to be a very effective feature in texture classification.
