Proposed Content Based Medical Image Retrieval Using Texture Descriptor

Texture is an innate property of all surfaces referring to visual patterns not resulting from the presence of a single color or intensity. Albeit being intuitively obvious, texture lacks a precise definition. Humans often distinguish textures with properties like periodicity, directionality, granularity, and randomness. Because of the importance and usefulness of texture information, various texture representations for diverse application areas in pattern recognition and computer vision have been extensively researched over the last decades and these achievements are now being adapted also to Content Based Image Retrieval applications (Manjunath and Ma 1996). Generally, an image can be considered to be composed of a number of salient regions with different texture patterns and the properties of these regions can be used in image indexing. Hence texture is an important feature that can be considered for any image representation.
