Unsharp Masking-Based Image Enhancement of Nanodispersed 10O.O6 Liquid Crystal Compound

The main motto of the image enhancement in image processing is to process an image with suitable technique and to provide better visibility for a specific application. Novel image processing techniques are required to identify key features like transition temperatures, clear phase identification in the liquid crystalline images. Characterization and mesomorphic behavior in pure and 1% ZnO nanodispersed liquid crystalline N–(p–n–decyloxybenzylidene)–p–n–hexyloxy anilines, 10O.O6 compounds, are carried out using a polarizing microscope and images are preserved for enhancement. Both the compounds exhibit NACIG phases, and the transition temperatures of the 1% ZnO nanodispersed 10O.O6 are reduced compared with pure 10O.O6. Further, in this work, a novel image enhancement technique of combined unsharp masking is proposed on pure and 1% ZnO nanodispersed 10O.O6 liquid crystalline compounds for better visibility of phases at transition temperatures. The proposed method is used to identify the uniform regions and to detect the defects which may not be clearly observed from polarizing microscope.
