Convolution (DE: Faltung): In digital image processing convolutional filtering plays an important role in many important algorithms in edge detection and related processes.
PixIsight provides 3 tools for convolution:
- Convolution
- LarsonSekania
- UnsharpMask
- gconv(): is a function of PixelMath - performs a convolution of the specified image with a Gaussian filter and generates a new image with the convoluted contents
In contrast to convolution, deconvolution attempts to restore the original image.
