Rotating Kernel Transformation (Lee & Rhodes)
The Rotating Kernel Transformation convolves an image with several orientations of a kernel.
For a line-kernel, straight lines are emphasized. For larger kernels, it becomes computationally expensive.
The zip-archive contains 5 files:
1) rktfilt.m ... function for filtering
2) rktkern.m ... for creating a kernel
3) rkttest.m ... script for testing the example
4) rktexample.mat ... sample image
5) example.png ... example screenshot
Please use
'help rktfilt' or 'doc rktfilt',
'help rktkern' or 'doc rktkern'
for help.
