CV_Blur function to blur image using normalised box filter dst = CV_Blur(srcimg,ksize_width,ksize_height,anchor_x,anchor_y,border_type) srcimg : Source image. ksize_width, ksize_height : blurring kernel size. anchor_x, anchor_y : x,y coordinates of anchor point border_type : border mode used to extrapolate pixels outside of the image. This function can be used for blurring image using normalised box filter. Image can be of any depth and have any no of channels. border_type can be : BORDER_REPLICATE: aaaaaa|abcdefgh|hhhhhhh BORDER_REFLECT: fedcba|abcdefgh|hgfedcb BORDER_REFLECT_101: gfedcb|abcdefgh|gfedcba BORDER_WRAP: cdefgh|abcdefgh|abcdefg BORDER_CONSTANT: iiiiii|abcdefgh|iiiiiii This is curretly dummy function. It provides no functionality but is required for providing support for generating C code for OpenCV CV_Threshold, CV_CvtColor Siddhesh Wani
