【摘要】 针对彩色图像的细节丰富和边界明显特点,提出了基于像素类型的局部自适应滤波方法。该方法首先检测彩色图像的边界点,再按照设定参数选择自动选择局部灰度平稳区,然后根据选定领域范围内像素的统计特性来判断中心像素的类型。结合邻域大小和像素类型,设计了不同的滤波模板。该方法不需人为选定待滤波区域,对噪声适应性强,且运算时间短,效果明显。更多还原

【Abstract】 According to characteristics of color images,a simple local adaptive filtering algorithm based on pixel style is proposed.In the filtering process,the edge pixels of color image is detected first;then local gray level me-adow based on specified parameter is selected,finally,the pixel style is determined by statistic characteristic of the selected local area.Different filter templates are designed according to the bulk of selected area and pixel type.更多还原
