Generates an alpha channel using only convolution matrix operations.
The output is clamped in 0-1 range and black/white inversion is available.
This tool is also very useful when applied multiplicatively over a background to recover details.
The 'Influence' parameter allows you to control how much each of the red, green, and blue channels contributes to the result of the matrix operations
