Analysis for a 16 bit image
For a panel size of 4 ,
bits in original image : 4x4x16
bits in compressed image : 32
Compression Ratio : 8
Original ImageBMP size : 9098 bytes 
JPEG File ( ImageMagick )JPEG Size : 1080 bytes Time taken : about 0.5 secs 

Fractal CompressionCompression at Panel Size 4FIF file size : 1036 bytes , zipped : 996 Time taken : about 5 seconds The FIFZIP file is smaller compared to the JPEG file ! Decoded at Panel Size 4 Panel Size 8 
Original Images 

Compression at Panel Size 2FIF size : 4108 bytes , zipped : 3449Time taken : about 8 secs Decoded at Panel Size 2 Panel Size 4 Panel Size 8 One can observe the difference between the Fractal Decoded images and the zoomed images. Fractal decoded images appear to show much detail then their corresponding zoomed counterparts.
