We have proposed the use of Gabor wavelet features for texture analysis and provide a comprehensive experimental evaluation of this algorithm on a large texture image database.
The basic idea is to extract features at multiple scales and orientations using a Gabor wavelet decomposition. These features compare favorably with other existing texture analysis algorithms. In particular, comparisons are made with orthogonal wavelet transform features and multi-resolution simultaneous autoregressive model features. Our experimental results indicate that the Gabor features have the best pattern retrieval performance.
» Texture features of the Brodatz album (1856 feature vectors (rows) - each containing 48 dim vector)
There are six different texture feature extraction schemes included in the evaluation:
The texture database used in the experiments consists of 116 different large texture images. Each one is 512x512 pixels and is divided into 16 non-overlapping subimages, each 128x128 pixels in size, thus creating a database of 1856 texture images. The following figure shows the demo program which is used to compare the performance of different texture features. The upper half part of demo shows the samples from the 116 texture classes, and the lower half part displays the query pattern (upper left) and its top matches from the database. They are shown in row scan order with increasing distance.
