TLDR
In this article, the texture energy approach requires only a few convolutions with small (typically 5x5) integer coefficient masks, followed by a moving-window absolute average operation.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.read more

Comparative Analysis of Region of Interest of Different Sizes for Breast Density Classification
TL;DR: It has been observed that a square shaped ROI having size of 200 × 200 pixels is optimal and it should be taken from the central breast region immediately behind the nipple, as this region is the densest region of the breast excluding pectoral muscle.

Automated cloud classification using a ground based infra-red camera and texture analysis techniques
TL;DR: In this article, a ground-based infrared (8-14 μm) imaging device mounted on a pan/tilt unit for capturing high spatial resolution sky images was used to extract 45 separate textural features using statistical and spatial frequency based analytical techniques.

Refining Region Estimates
TL;DR: No parameters are required, the technique is invariant under constant scalings of the image intensities, and it is relatively insensitive to the position and topology of the initial segmentation.

On Textures: A Sketch of a Texture-Based Image Segmentation Approach
T. Hermes,A. Miene,P. Kreyenhop +2 more
TL;DR: In the context of this work, a new approach of domain- independent texture segmentation is presented, which is implemented by a combination of region and edge-oriented segmentation methodes.

A new improved Laws-based descriptor for surface roughness evaluation
TL;DR: In this paper, a new descriptor that allows to classify turned metallic parts based on their superficial roughness is proposed, which is based on a vision system that calculates the actual roughness by analysing texture on images of machined parts.

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.
