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.
