ABSTRACT
Analysis of textures is performed with finite number of grains in exploring the statistical properties that are obtained experimentally and analyzed for gray level coocurrence features. The article attempts novel method in analysis of liquid crystalline mesogen exhibiting nematic texture with image processing techniques for variety of features and its relevance to the texture quantitatively. The texture possesses orientation property with rod like molecules along the director where the centre of symmetry coincides with centre of gravity. The nematic texture is obtained for p-azozyanisole is thermotropic liquid crystal which is monotropic that experience the same texture in both heating and cooling process. The results of measurements reveal that it has minimum energy associated with clusters formed during the transition with low energy and entropy responsible for first order transition along with relevant attributes responsible for texture in the entire process.
