The authors proposed the texture unit-based texture spectrum approach in 1990, which has been used for texture analysis, including texture characterization, texture classification, texture edge detection, and textural filtering. One of the most important disadvantages related to this method is the large number of texture units (6,561) and its redundancy. This paper aims at simplifying the origi...

Texture is one of the visual features used in Content Based Image Retrieval (CBIR) to represent the contents of the image with respect to the characteristics brightness, color, shape, size, etc. Texture is a property that represents spatial distribution of an Image. Texture can be defined as a repetition of an element or pattern in a problem space. Texture analysis can be used for classificatio...

Osteoporosis is a bone pathology inducing an increased fragility of the skeleton. With the lengthening of the duration of life, this pathology is going to concern an increasing population. A better knowledge of the quality of the bone structure can help a best prevention of the fracture risk. The bone mineral density is not the unique factor to determine the quality of the bone structure. The t...

Ultrasound imaging is commonly used for breast cancer diagnosis, but accurate interpretation of breast ultrasound (BUS) images is often challenging and operator-dependent. Computer-aided diagnosis (CAD) systems can be employed to provide the radiologists with a second opinion to improve the diagnosis accuracy. In this study, a new CAD system is developed to enable accurate BUS image classificat...

Age-related Macular Degeneration (AMD) is a leading cause of legal blindness. As the disease progress, visual loss occurs rapidly, therefore early diagnosis is required for timely treatment. Automatic, fast and robust screening of this widespread disease should allow an early detection. Most of the automatic diagnosis methods in the literature are based on a complex segmentation of the drusen, ...
