Representing Texture Images Using Asymmetric Gray Level Aura Matrices
نویسندگان
چکیده
In this paper, we present a new mathematical framework for modeling texture images. Under this new framework, we prove that the Asymmetric Gray Level Aura Matrices (AGLAMs) of a given image have the necessary and sufficient information to represent the image. Using AGLAMs, a new similarity measure is defined, which is a one-to-one metric in the sense that zero distance between two images will guarantee that the two images are the same. To the best of our knowledge, none of the existing measures has this property. Applications such as learning for image retrieval and texture synthesis can be applied using AGLAMs. The experimental results show that the new AGLAM-based distance measure outperforms existing distance measures in the above mentioned applications.

Texture Image Classification using Basic Gray Level Aura Matrices
We present a new method for texture image classification using Basic Gray Level Aura Matrices (BGLAMs). Given an unseen texture image, our approach classifies it into one of the pre-learned classes, each of which is characterized using BGLAMs. There are two stages in our algorithm: a learning stage and a classification stage. In the first stage, models of texture classes are learned from the BG...
متن کاملContent based mammogram retrieval using Gray Level Aura Matrix
Diagnosis of breast cancer in mammograms is also for specialists a difficult and error-prone task. A good opportunity to support radiologists in their decision is to find similar mammograms out of a database to compare the current case with past cases. In this work a complete content based image retrieval (CBIR) system for mass and calcification class mammograms has been implemented under usage...

This paper presents a preliminary study for mapping sea ice patterns (texture) with 100-m ERS-1 synthetic aperture radar (SAR) imagery. We used gray-level co-occurrence matrices (GLCM) to quantitatively evaluate textural parameters and representations and to determine which parameter values and representations are best for mapping sea ice texture. We conducted experiments on the quantization le...
