Class SoGaborFilteringProcessing2d

  • All Implemented Interfaces:

    public class SoGaborFilteringProcessing2d
    extends SoImageVizEngine
    SoGaborFilteringProcessing2d image filter. The SoGaborFilteringProcessing2d engine makes filtered images thanks to Gabor filters, which are well known for localisation in frequency and space. All these filters are made in the Fourier Space (frequency space). Gabor filters recover this space.

    For a number of angles and a number of frequences , we can define filters of Gabor :

    • for the angles ,
    • and the frequencies . being the Nyquist frequency.

    The frequency responses are: where , , , and being the centered and normalized coordinates.

    File format/default:

    GaborFilteringProcessing2d {

      inImage NULL
      frequencyNumber 4
      angleNumber 4
