Improving LBP and its variants using anisotropic diffusion
This is an incremental improvement for texture classification in computer vision.
The paper tackles texture recognition by proposing a preprocessing step using anisotropic diffusion to improve local feature descriptors, showing that this approach leads to improved texture recognition results.
The main purpose of this paper is to propose a new preprocessing step in order to improve local feature descriptors and texture classification. Preprocessing is implemented by using transformations which help highlight salient features that play a significant role in texture recognition. We evaluate and compare four different competing methods: three different anisotropic diffusion methods including the classical anisotropic Perona-Malik diffusion and two subsequent regularizations of it and the application of a Gaussian kernel, which is the classical multiscale approach in texture analysis. The combination of the transformed images and the original ones are analyzed. The results show that the use of the preprocessing step does lead to improved texture recognition.
