Abstract
A method is presented for classifying each pixel of a textured image, and thus for segmenting the scene. The "texture energy" approach requires only a few convolutions with small (typically 5x5) integer coefficient masks, followed by a moving-window absolute average operation. Normalization by the local mean and standard deviation eliminates the need for histogram equalization. Rotation-invariance can also be achieved by using averages of the texture energy features. The convolution masks are separable, and can be implemented with 1-dimensional (vertical and horizontal) or multipass 3x3 convolutions. Special techniques permit rapid processing on general-purpose digital computers.

Automated analysis of MR image of hip: geometrical evaluation of the Legg-Calve-Perthes disease.

TL;DR: The AHI appears to be the best discriminant attribute (maximum between-class variance ratio) and cross-validation tests indicate that it can at most reduce the parameters to five (AHI, CC'D, DHF, DCF and VCE).

Stratified squamous epithelial biopsy image classifier using machine learning and neighborhood feature selection

TL;DR: A machine learning based automatic oral squamous cell carcinoma (OSCC) classifier named as Stratified Squamous Epithelial Biopsy Image Classifier (SSE-BIC) is developed to categorize H&E-stained microscopic images of squamous epithelial layer in four different classes: normal, well- Differentiated, moderately-differentiated and poorly- differentiated.

TL;DR: In this paper, the success rates of Haar, Daubechies-6 and Coiflet-6 wavelet transforms are estimated based on first-order statistics on the entire image.

Textural Features for Image Classification

TL;DR: These results indicate that the easily computable textural features based on gray-tone spatial dependancies probably have a general applicability for a wide variety of image-classification applications.

Textured Image Segmentation

TL;DR: In this article, texture energy is measured by filtering with small masks, typically 5x5, then with a moving-window average of the absolute image values, leading to a simple class of texture energy transforms, which perform better than any of the preceding methods.
