public class Whistles2Image extends org.jamdev.jdl4pam.transforms.FreqTransform
Transform whistles to an image. Here we extend the FreqTransform class because it contains lots of image transforms that are useful once the whistles have been converted into an image.

    • whistContours2Points

      public static ArrayList<double[][]> whistContours2Points(SegmenterDetectionGroup whistleGroup)
      Convert a list of whistle contours to a list of time and frequency points.
      Parameters:
      whistleGroup - - list of whistle contours within a detection group.
      Returns:
      an array with time (seconds from start of group) and frequency (Hz)

    • makeScatterImage

      public static BufferedImage makeScatterImage(ArrayList<double[][]> points, double[] size, double[] xlims, double[] ylims, double markerSize)
      Create a scatter image from points
      Parameters:
      points - - list of time frequency points - the points are time (milliseconds from 0) and frequency
      size - - the width and height of the image in pixels
      xlims - - the minimum and maximum time in milliseconds from 0;
      ylims - - the minimum and maximum frequency in Hz
      markerSize - - the marker size in pixels
      Returns:
      an image with y axis as frequency and x axis as time.
