Up for a more complex challenge?
Download both the CLIc Library and the CLIc template project. And compile the CLIc template project using CMake. Then modify the project to apply a 2D Gaussian Blur operation to an image.
Guideline and Troubleshooting can be found in the CLIc project documentation.
The current CLIc template project executable is configured to take an input .tif filename and an output .tif filename as parameters.
