Venkatesh, YV and Parthasarathy, M (1995) Principal components of Gabor decomposition for texture segmentation. In: Proceedings of Second Asian Conference on Computer Vision: ACCV '95, Vol.3, 5-8 December 1995, Singapore, pp. 762-766.Full text not available from this repository.
The paper deals with the problem of texture boundary detection or, equivalently, texture segmentation of images. A novel Gabor function-based technique has been proposed to solve the problem for a wide variety of textural images. The Gabor framework (involving bi-orthogonal functions) enables the decomposition of the image into multiple, independent layers containing spatial and spectral information with minimal uncertainty. This is believed to result in a better localization of textural boundaries than is possible using the methods (of the literature) not based on Gabor decomposition. An attempt is made to optimize the number of layers needed for image reconstruction by invoking the method of principal components. Using this set of `optimal' layers, a clustering algorithm has been used to group elements of the image having similar gradient values in this set of optimal layers. For lack of space, all the details are omitted, and only two examples are given in the final form in order to demonstrate the superiority of the proposed technique.
