The Radon transform-based analysis of bidirectional structural textures
In this work directional structural textures that consist of mostly straight lines are considered and the Radon transform-based approach to their directions detection is suggested. Problems of the detection of bidirectional structures are set forth in terms of image reconstruction from projections. In the proposed algorithm, using tomographic criteria of optimal decomposition of the texture image into a sum of two ridge functions, two directions determine the texture structure, are extracted. The selected two projections are jointly most informative and contain main features of regularly arranged bidirectional structures.
