procedure filter2D(dst: TIEVisionImage; kernel: TIEVisionImage; anchor: TIEVisionPoint); overload; safecall;
procedure filter2D(kernel: TIEVisionImage; anchor: TIEVisionPoint); overload; safecall;
Description
Convolve an image with the kernel.
First overload places the result into destination object.
Second overload updates the current image.
| Parameter | Description |
| dst | Container for the destination image |
| kernel | Convolution kernel (or rather a correlation kernel), a single-channel floating point matrix. To apply different kernels to different channels, split the image into separate color planes using splitPlanes and process them individually |
| anchor | Anchor of the kernel that indicates the relative position of a filtered point within the kernel. The anchor should lie within the kernel. The special default value (-1, -1) means that the anchor is at the kernel center |
Note: You can use
assignIEVisionImage to reflect this methods changes in the associated bitmap
