Gaussian blur is an image smoothing operation done by use of separable symmetric matrix of convolution coefficients.

[edit] Description

GBlur blurs the image as in out of focus or linear motion or rectangular grid. Full Discription

Gaussian blur is an image smoothing operation done by use of separable symmetric matrix of convolution coefficients. The size can be any odd nimber between 3 (for a 3x3 grid size) to 11 (for a 11x11 grid). Given the size and standard deviation, the convolution weights are computed and applied.. In YUV formats only the Y values are smoothed. However if u and or v are made true, those corresponding planes are also smoothed. In RGB formats all 3 color planes are smoothed.


  • For AviSynth+ see modPlus, includes high bit depth colorspace support and 64-bit.
