[fullName,metricName] = metricsSaveImage(figNum) Author: ImagEval Purpose: Save the metric image of the metrics window to an image file. The metricImage contains the currently computed metrics image. The image is saved in a TIFF file format. This routine adjusts the values so they fit in the TIFF scale. To save the data without adjustment, use menuSaveData. This writes the data into a Matlab file along with auxiliary information.
