Metacarpal phalangeal joint; index finger of hand shown in Figure 1.

Comparison of JPEG DCT vs. wavelet compression. Image fidelity is better maintained with JPEG DCT compression at comparable compression ratios.

   

   
   
A:  Wavelet image,  Q =  99,  compression ratio = 12:1.     
   
   
B:  JPEG image,     Q=  7.0,  compression ratio = 10:1.
   
   
C:  Wavelet image,  Q =  98,  compression ratio = 18:1.
   
   
D:  JPEG image,     Q=   32,  compression ratio = 19:1.
