imgCanny2--Performs Canny Edge Detection using gradient input instead of intensity input





Image Types

stdinFloat format, Float format
stdoutPBM format


This command works exactly like imgCanny, except that instead of passing in one image whose gradient is first computed, the gradient itself in the form of two float format images (the first x and the second y) is passed in. imgSmooth and imgEdgeSynth must still be run to complete the algorithm.

Treatment of Valid Region

The output valid region is set to the valid region defined for the first image in each group with an adjustment for the kernel size.

Treatment of Minimum and Maximum Values

The minimum and maximum values are calcluated during processing.
