Convolution 3x3

The Convolution 3x3 node applies a 3 by 3 convolution kernel to an image.

Inputs and Outputs

Inputs:

• Image (Image): The input image.
• Kernel (Matrix 3x3): The kernel matrix.
• Bias (Float): The contrast bias to be added to all color channels.

Outputs:

• Output (Image): The output image.

Example

Here we create an edge-detection effect by using a convolution (displayed in the inspector panel), followed by the Black and White node.
