Unsupervised Image Segmentation Using Textural Features

Abstract—In this study, a method was developed for the segmentation of the texture patterns in images containing multi-texture pattern. To distinguish these textures from one another, the image was divided into sections, and the textural features of each section were extracted using Gabor filters and gray level cooccurrence matrices. These features were analyzed using AGNES clustering algorithm and each section was assigned to a cluster. Segmentation was performed by marking as many different textural sections as the number of clusters formed on the actual image. The performance of the developed method was tested using the images obtained from Describable Textures Dataset database. The method made 37 correct segmentations for 40 images. In images with two different texture patterns, there were no incorrect segmentations. In 3 of the 32 images with three or four different texture patterns, incorrect segmentation was performed. Due to the sectioning of the image, borders between the texture patterns could not be precisely distinguished.
