All of the patches have a strength input, which can be controlled in the demo by clicking on the controller block and using the strength slider in the properties panel.
TIP! If you are using gaussian blur, a more performant option is to chain two directional blurs together (one horizontal, one vertical).
Numbers in the patch names signify the size of the kernel that is used. Lower is better for performance, higher is better for quality.
Blur that accepts a vector for directional blurring. Direction vector is normalized, so any range of numbers is acceptable
General purpose convolution patches that are used as a base for the other patches.
Really good looking sharpening. Just wow. Great job.
Harsh sharpening, good for enhancing small details.
Gaussian blur. You know the one.
Boxy edge detector.
