cv_bilateralfilter

Bilateral Filtering the Input Image

Calling Sequence

img_ret=cv_bilateralfilter(image,d,sigmaColor,sigmaSpace)

Arguments

image

Input Image

d

Diameter of each pixel neighborhood that is used during filtering

sigmaColor

Filter sigma in the color space. A larger value of the parameter means that farther colors within the pixel neighborhood will be mixed together, resulting in larger areas of semi-equal color.

sigmaSpace

Filter sigma in the coordinate space. A larger value of the parameter means that farther pixels will influence each other as long as their colors are close enough. When d>0 , it specifies the neighborhood size regardless of sigmaSpace . Otherwise, d is proportional to sigmaSpace.

img_ret

Returned Image after filtering

Description

Provides Bilateral Filtering to Input image

This filter can reduce noise of the image while preserving the edges. The drawback of this type of filter is that it takes longer to filter the input image.

Examples

img_ret=cv_bilateralfilter(input_image,2,75,75)
