Description Usage Arguments Details Value Author(s) See Also Examples

Given a convover and two images (the source and the kernel), this method performs a convolution of the two images and returns the result. Convolution is performed using the give convolver, which must be created using profitMakeConvolver.

1	profitConvolve(convolver, image, kernel, mask = NULL)

`convolver`	The convolver object that will perform the convolution. It must be created using `profitMakeConvolver`.
`image`	The source image to convolve.
`kernel`	The kernel user to convolve the image with.
`mask`	Logical; If not `NULL`, it has the same size of the source image, and indicates the pixels of the resulting image that should be part of the output (if `TRUE`), or left as `0` (if `FALSE`).

...

The output is the result of the convolution of the image and the kernel.
