Abstract

In this paper, we suggest a new direct method for image segmentation using texture and color information combined through a mutivariate linear discriminant algorithm. The color texture is computed in nine 3?3 masks obtained from each 3?3?3 spatio-spectral neighborhood in the image using the classical Haralick and pressman texture features. Among these 9?28 texture features the best set was extracted from a training set. The resulting set of 10 features were used to segment an image into four different regions. The resulting segmentation was compared to classical color and texture segmentation methods using both box classifiers and maximum likelihood classification. It compared favourably on the test image from a Fastred-Lightgreen stained prostatic histological tissue section based on visual inspection. The classification accuracy of 97.5% for the new method obtained on the training data was also among the best of the tested methods. If these results hold for a larger set of images, this method should be a useful tool for segmenting images where both color and texture are relevant for the segmentation process.
