Scale Invariant Texture Analysis Using Multi-scale Local Autocorrelation Features
We have developed a new framework for scale invariant texture analysis using multi-scale local autocorrelation features. The multiscale features are made of concatenated feature vectors of different scales, which are calculated from higher-order local autocorrelation functions. To classify different types of textures among the given test images, a linear discriminant classifier (LDA) is employe...
متن کاملInvariant Features for Gray Scale Images
Invariant features are image characteristics which remain unchanged under the action of a transformation group. We consider in this paper image rotations and translations and present algorithms for constructing invariant features. After brieey sketching the theoretical background we develop algorithms for recognizing several objects in a single scene without the necessity to segment the image b...
متن کاملComputer-aided mass detection in mammography: false positive reduction via gray-scale invariant ranklet texture features.
In this work, gray-scale invariant ranklet texture features are proposed for false positive reduction (FPR) in computer-aided detection (CAD) of breast masses. Two main considerations are at the basis of this proposal. First, false positive (FP) marks surviving our previous CAD system seem to be characterized by specific texture properties that can be used to discriminate them from masses. Seco...
متن کاملExtraction of Noise Tolerant, Gray-Scale Transform and Rotation Invariant Features for Texture Segmentation Using Wavelet Frames
In this paper, we propose a texture feature extraction scheme at multiple scales and discuss the issues of rotation and gray-scale transform invariance as well as noise tolerance of a texture analysis system. The nonseparable discrete wavelet frame analysis is employed which gives an overcomplete wavelet decomposition of the image. The texture is decomposed into a set of frequency channels by a...
متن کاملMulti-scale gray level co-occurrence matrices for texture description
Texture information plays an important role in image analysis. Although several descriptors have been proposed to extract and analyze texture, the development of automatic systems for image interpretation and object recognition is a difficult task due to the complex aspects of texture. Scale is an important information in texture analysis, since a same texture can be perceived as different text...
