returns a saliency map for image.

Details and OptionsDetails and Options

  • ImageSaliencyFilter returns a single-channel image where pixel intensities represent a saliency measure for the input image.
  • ImageSaliencyFilter is typically used to focus on regions of an image that have features that stand out as different. A higher saliency value is taken to be more important.
  • ImageSaliencyFilter works on images with an arbitrary number of channels.
  • Possible settings for the Method option are:
  • "Itti"saliency based on color, intensity, and orientation
    "IttiColor"color map of the Itti algorithm
    "IttiIntensity"intensity map of the Itti algorithm
    "IttiOrientation"orientation map of the Itti algorithm
    "HistogramContrast"saliency based on mean color difference to image pixels
    "SpectralResidual"saliency based on the residual of the log spectrum
    "ImageSignature"saliency based on foreground estimation
  • The Itti algorithm is based on human visual saliency. For all methods based on this algorithm, calculations are performed in the RGB color space.
  • For all Itti-based methods, different scales of the image are compared with each other. With Method->{"method",{σ1,σ2,},{step1,step2,}}, scale is compared with coarser scales for all j. The default setting is .
