The "MaskedConvolve" operation extends JAI's convolve operator by providing
the option to select which source and or destination pixels are included in processing
using an associated ROI object.
Constant that can be used for the minCells parameter to require
all non-zero kernel cells to overlap with unmasked source image
cells for convolution to be performed for a terget cell
Constant that can be used for the minCells parameter to specify
convolution will be performed for a terget cell if any non-zero kernel
cells overlap with unmasked source image cells.
