jit.fastblur

Optimized blur/sharpen

Description

The jit.fastblur object performs several special-case convolution blur/sharpen operations on incoming matrices. Although it is less flexible than the jit.convolve object, the jit.fastblur object will be quicker and easier to set up for the equivalent convolution, in most cases.

Matrix Operator

matrix inputs:1, matrix outputs:1

Information for Jitter Matrix Operator (MOP) messages and attributes to this object

Attributes

Name	Type	g/s	Description
center	float		The mathematical weighting of the center pixel when performing convolution (default = 1.)
mode	int		The kernel shape (default = 0 (row)) 0 = row 1 = column 2 = cross 3 = diagonal 4 = square
range	int		The number of pixels from the center pixel of the convolution kernel to its edge (default = 1)
ring	float		The mathematical weighting of cells adjoining the center pixel when performing convolution (default = 1.)
ripple	float		The scaling applied to outer cells when performing convolution (default = 1.) The second ring of pixels is scaled by this factor in relation to the ring attribute when performing convolution, while the third ring is scaled in relation to the second.
