Digital Image Processing (DIP) with Khoros 2

Khoros Bugs and Suggestions

At the time this course was released the following known bugs exists. These will be corrected in future releases of khoros.

Linear operator does not implement circular convolution and has a bug in linear convolution.
solution: extend pad the image with 0 for linear convolution and extend replicate the image for circular convolution.
afterwards extracts the proper portion from the resultant image.
Linear operator has a bug when the input image has width 1.
solution: replicate the width to 2, apply the convolution and then extract a single width.
Linear operator has a bug when performing correlation. The origin of the kernel is reflected.
solution: use explicitly the reflected value for the kernel origin.
Histogram operator does not generate a cumulative histogram as output.
solution: use convolution to create the cumulative histogram from the histogram.
