Inheritance diagram for canny_Filter:
This filter uses the canny method to detect the edges of an image.
The process includes the following steps:
An edge from this filter is a 0 value and a non-edge is 255.
The Gaussian mask can be turned on or off using canny_Filter::enableGaussian() or canny_Filter::disableGaussian().
The Sobel approximation can also be turned off, but this turns of the canny computation as well. Toggling the Sobel/Canny code is done with canny_Filter::enableSobelApprox() and canny_Filter::disableSobelApprox().
Supports the following formats:
The canny_Filter is a custom filter for Phission that outputs thicker lines than the OpenCV canny filter does.

Make timing part of the phFilter class ???
verify all the algorithms in the canny_Filter
Output thin lines? or ar ethe thick ones good ?
When > 8bit channels are supported, make sure that the edge/non-edge values are appropriate minimum/maximum values
add example application code that shows how the processed images were output
