SaliencePoints

The module SaliencePoints takes a list of image coordinates and convert it into a saliency map that is suitable as input to the SaliencyMap module. The list must be coded as rows with (x,y)-values. The column with the coordinates can be set using the select parameter. A column with saliency values can optionally be selected using the select_salience parameter. If the COUNT input is connected it indicates the number of rows in the input to use.
