Convolve

• Spatial Filters

  Spatial filters is set of spatial filters that uses the convolution mask for filtering the image.

  Options

  Spatial filters’s options are consisted of following four parts: Preset, Convlolution Mask, Additional Operation, Enhance.

  

  • Preset

    Preset is set of filters that has unique convolution mask. By default, about 30 kinds of filters are provided.

  • Convolution Mask

    Convolution mask is defined by an n by n matrix. Currently only 3 x 3 matrix is supported.

  • Addtional Operation

    Addtional Operation is used to detect edge or error of the image.

  • Enhance

    Enhance is used to addtion the result of filtering image to the original image.
