摘　　要：提出了基于噪声检测的开关矢量中值滤波,在噪声检测阶段根据噪声的定义将标量检测和矢量检测结合在一起,有效地提高噪声检测的准确性;由于采用开关矢量滤波,滤波过程只对在标量预检测中被检测出的噪声像素进行,可大大减少计算量并能较好地保持图像的细节和边缘,而且在滤波过程中不会出现新的颜色。A detail-preserving adaptive switching vector median filter is proposed in the paper.To improve the degree of accuracy of noise detection,scalar detection and vector detection is combined.Using switching vector median filter,filtering is used only if the pixel is noise during the scalar detecting.This method is computationally efficient and provides excellent balance between noise attenuation and detail preservation.Besides,the method ensures the original color.
