Surface morphology and physicochemical properties induced to capillary uptake of liquids. Topography shows the surface characteristics which induced to roughness. Roughness influences the wettability and cleanability. Plasma modification (Oxygen and Ammonia) tends to play an important role in wettability of PET fabric. Wetting phenomena i.e. spreading rate, absorption rate and static contact angles are observed to indicate the intensity of hydrophilicity and hydrophobicity, before and after modification. Thermofixing modify the amplitude and porosity of yarn and that leads to change in...

This book describes a curvature-based corner detector that detects both fine and coarse features accurately at low computational cost. First, it extracts contours from a Canny edge map. Second, it computes the absolute value of curvature of each point on a contour at a low scale and regards local maxima of absolute curvature as initial corner candidates. Third, it uses an adaptive curvature threshold to remove round corners from the initial list. Finally, false corners due to quantization noise and trivial details are eliminated by evaluating the angles of corner candidates in a dynamic...
