Rotation Invariant Texture Classification Using Gabor Wavelets
A method of rotation invariant texture classification based on spatial frequency model is developed. Features are derived from the multichannel Gabor filtering method. The classification performance is first tested on a set 1440 samples of 15 Brodatz textures rotated in 12 directions (0 to 165 in steps of 15 degrees). For the 13-class problem reported in [13] we got better classification with o...
متن کاملTexture Classification Based on Gabor Wavelets
This paper presents the comparison of Texture classification algorithms based on Gabor Wavelets. The focus of this paper is on feature extraction scheme for texture classification. The texture feature for an image can be classified using texture descriptors. In this paper we have used Homogeneous texture descriptor that uses Gabor Wavelets concept. For texture classification, we have used onlin...

It also points to the literature and connections with related methods. The unnnishedness of the research in this area becomes clear from the discussion of some extra issues and from a short list of practical a...
متن کاملRotation and Scaling Invariant Texture Classification Based on Gabor Wavelets
In this paper, an efficient texture classification method is proposed, which not only considers the effect of rotation, but also is scaling invariant. In our method, the Gabor wavelets are adopted to extract local features of an image, and the statistical property of the intensity values is used to represent the global feature. Then, an adaptive circular orientation normalization scheme is prop...
متن کاملSpherical Wavelets: Texture Processing
Wavelets are a powerful tool for planar image processing. The resulting algorithms are straightforward, fast, and efficient. With the recently developed spherical wavelets this framework can be transposed to spherical textures. We describe a class of processing operators which are diagonal in the wavelet basis and which can be used for smoothing and enhancement. Since the wavelets (filters) are...
