BilateralFilter
The BilateralFilter block reduces unwanted noise by blurring the input image while keeping the edges sharp.
Library
ComputerVision/Images/Filters
Description
To achieve this, the BilateralFilter finds the weighted average of the neighborhood around the pixel (GaussianBlur), then considers blurring only nearby pixels and pixels with similar intensity to the central pixel. In doing so, the BilateralFilter block preserves edges where pixels have large intensity.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
diameter | Diameter | Specifies the diameter of the pixel neighborhood used during filtering. | Scalar | |
sigmaColor | Sigma Color | Determines the range of pixel values such that pixel value x will be replaced with similar pixel values. This results in large areas of semi-equal pixel values. The larger the filter value, the stronger the effect on the image, which makes the image appear smoother and more cartoonish. | Scalar | |
sigmaSpace | Sigma Space | Determines the range of pixel values such that pixel value x will be replaced with similar pixel values. This results in large areas of semi-equal pixel values. The larger the filter value, the stronger the effect on the image, which makes the image appear smoother and more cartoonish. | Scalar | |
externalActivation | External activation | This parameter defines if the block receives or inherits an external activation. When External Activation is used, an additional activation port is added to the block. Default is OFF. | Number | 0 |
