    • PURPOSE: An image boundary clarification apparatus and a method thereof are provided to improve reliability of a depth map, by calculating a weighted value using random walk probability and applying the calculated weighted value to a bilateral filter. CONSTITUTION: A block separation part separates an image into a block unit of fixed size (S710). A random walk weight calculator calculates cost value, and calculates a weighted value by subtracting the calculated cost value (S730). A filtering part filters the image, by calculating an average among adjacent pixels by using the calculated weighted value (S740). [Reference numerals] (AA) Start; (BB) End; (S710) Divide an image into a block unit; (S720) Calculate cost value; (S730) Calculate weighted value; (S740) Equalize the value of adjacent pixels
    • 目的:提供一种图像边界澄清装置及其方法,以通过使用随机游走概率计算加权值并将计算的加权值应用于双边滤波器来提高深度图的可靠性。 构成:块分离部将图像分割成固定尺寸的块单位(S710)。 随机步行权重计算器计算成本值,并通过减去计算出的成本值来计算加权值(S730)。 滤波部分通过使用计算的加权值计算相邻像素之间的平均值来对图像进行滤波(S740)。 (附图标记)(AA)开始; (BB)结束; (S710)将图像划分为块单位; (S720)计算成本值; (S730)计算加权值; (S740)相邻像素的值相等
