1. In my script, the image compare was invoked as:

   label = "Image compare"
   image1 = "/home/mukta/image1.png"
   image2 = "/home/mukta/reimage1.png"
   TestImage.compare(label, image1, image1, metric='PSNR')
   TestImage.compare(label, image1, image2, metric='PSNR')
   TestImage.compare(label, image1, image1, metric='MSE')
   TestImage.compare(label, image1, image2, metric='MSE')

   The output in the log file was:
   2005.11.18 20:43:10     Image compare:  Failed - inf dB
   2005.11.18 20:43:10     Image compare:  Failed - 32.2696 dB
   2005.11.18 20:43:10     Image compare:  Failed - 0 dB
   2005.11.18 20:43:10     Image compare:  Failed - 2.54674e+06 dB

2. The version of ImageMagic is 6.2.5.
   $compare -version
    Version: ImageMagick 6.2.5 10/18/05 Q16 http://www.imagemagick.org

3. Also, when I run the compare command on the commandline, it gives me an 
   output whose length is 3 and hence TCImage.compare() returns the result as 
   'failed'.
   $compare -metric "PSNR" ./image1.png ./reimage1.png z.png
   $32.2696 dB
   $48,48,PNG
   $
