Image to apply custom convolution kernel

Kernel Size

Size of the convolution matrix

Kernel Values *

Matrix values (left to right, top to bottom). For 3x3: 9 values, for 5x5: 25 values, etc.

Intensity

Strength of the convolution effect (0.1-10.0)

Normalize Kernel

Normalize kernel so that sum of all elements equals 1 (except for edge detection)

Output Mode

Additional processing on the output
