Basic| Module: | OpenCV |
|---|
Smoothes image using normalized box filter.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inSrc | Image | Source image. | |
|
inKWidth | Integer | 0 -  |
Smoothing kernel width. |
|
inKHeight | Integer | 0 - |
Smoothing kernel height. |
|
inAnchor | Location* | Anchor point. The NIL value means that the anchor is at the kernel center. | |
|
inBorderType | CvBorderType | Border mode used to extrapolate pixels outside of the image. | |
 |
outDst | Image | Output image. | |
Description
The operation smooths inImage with matrix of size inKWidth x inKHeight with all elements equal 1/(inKWidth x inKHeight).
Examples
 |
 |
cvBlur performed on sample image with inKWidth = 5, inKHeight = 5, inBorderType = BORDER_REPLICATE.
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | Border type can be BORDER_* except BORDER_TRANSPARENT and BORDER_ISOLATED in cvBlur. |
| DomainError | Input image must have pixel type different from Int8 and Int32 in cvBlur. |
Complexity Level
This filter is available on Basic Complexity Level.
