Class: ConvolutionKernel.
This class can implement a general square convolution kernel, or can generate one procedurally.
The procedural Kernel generator implements a 2D gaussian shaped image sharpening (or blurring kernel). The type of sharpening performed is typically called unsharp masking. The filter weights are detemined by the formula:
2 2 2 2
-( ( dx + dy ) / (2 * sigma * radius ) )
e
where: dx = x distance from center of kernel dy = y distance from center of kernel
This creates a circularly symmetric, Gaussian shapped kernel. The filter weights are then normalized so their sum = 1.0 and to produce an output that computes:
(1+sharpness)*I - sharpness*G
where I is the original image G is the orignal image with the gausing kernel applied.
Here are some example kernels with the default sharpness factor, 0.5, for various radii:
-0.00002 -0.0006 -0.0020 -0.0006 -0.00002
-0.00006 -0.0053 -0.00006 -0.0006 -0.0189 -0.0581 -0.0189 -0.0006 -0.0053 1.0215 -0.0053 -0.0020 -0.0581 1.3210 -0.0581 -0.0020 -0.00006 -0.0053 -0.00006 -0.0006 -0.0189 -0.0581 -0.0189 -0.0006 -0.00002 -0.0013 -0.0020 -0.0013 -0.00002
Radius = 1 Radius = 2
The default kernel is:
-0.0057 -0.0419 -0.0057
-0.0419 1.1903 -0.0419
-0.0057 -0.0419 -0.0057
The sharpness typically ranges from -1 for maximum blur (makeing a standard gaussian blur), to 0 for no effect, to positive values up to about 10 for various degrees of sharpening. Values greater than 1 create a very pronounced sharpening effect. The radius can be any non-negative value. A radius of zero will perform no filtering, while successively larger values will filter lower and lower frequencies. The actual kernel size is determined by the formula:
width,height = 1 + 2*(int)radius
Thus, a radius of 1.5 (the default) will create a 3x3 kernel.
Typically the parameters you would use for:
Low Sharpen – Sharpness = 5.0, Radius = 1.5 Medium Sharpen – Sharpness = 7.5, Radius = 1.75 High Sharpen – Sharpness = 10.0, Radius = 2.0
For a Sharpen tool, the typical ranges would be 0.0 to 10.0 for Sharpness, and 1.0 to 4.0 for Radius
Blur values would be as follows:
Low Blur – Sharpness = -1.0, Radius = 3.0 Medium Blur – Sharpness = -1.0, Radius = 8.0 High Blur – Sharpness = -1.0, Radius = 32.0
For a blur tool, the Sharpness value would be fixed at -1.0, and the typical range for the user to select radius would be 1.0 to 32.0. The blur kernels generated by this class are seperable.
