plotSalientLocation

PURPOSE ^

plotSalientLocation - plots the attended location into an existing figure.

SYNOPSIS ^

function plotSalientLocation(winner,lastWinner,img,params,varargin)

DESCRIPTION ^

 plotSalientLocation - plots the attended location into an existing figure.

 plotSalientLocation(winner,lastWinner,salParams,shapeData)
    Plots the winning location into the current figure. 
    Depending on the settings in salParams, the contour of the 
    attended region or a circle centered at the attended location 
    is drawn in yellow. If there is a valid lastWinner, 
    a red line connects lastWinner with winner.
       winner: the attended location in image coordinates.
       lastWinner: the previously attended location (-1 for none).
       salParams: structure with saliency parameters.
       shapeData: structure array with information on the attended 
          region from estimateShape.

 plotSalientLocation(winner,lastWinner,salParams)
    If no shapeData are passed, a circle is drawn at the attended
    location.

          contrastModulate, emptyMap, defaultSaliencyParams.
