Method and apparatus for measuring color-texture distance, and method and apparatus for sectioning image into a plurality of regions using the measured color-texture distance

摘要

Color-tekseuchueo the distance measuring method and a cell decomposition of the image using this device and the method and apparatus is disclosed. This distance measuring method is a luminance difference, between given two points on the color feature space composed of the color characteristic value with that pixel of the image, the saturation difference and the given different importance respectively to the color difference, and proportional to the assigned importance brightness difference, saturation difference and the weighting to be imposed on the multi-size tekseuchueo characteristic difference and tekseuchueo between given two points on adding the color difference by calculating the color distance between the two points and, tekseuchueo feature space consisting of tekseuchueo characteristic value for the pixel stage by a coefficient to obtain a tekseuchueo distance between two points, and multiplied by the color weighting the color distance, multiplied by the tekseuchueo weighted tekseuchueo distance and adds the multiplied result to the color between the two points - the step of obtaining the tekseuchueo distance provided, and the color is more important than luminance and saturation, and the luminance is more accessible to the absolute value of the color is black, The degree to access absolute color is characterized by determination of the importance from the fact that has a random value.
