Abstract
A simple and efficient method of subband coding of digital images
is reported. First, a technique for designing symmetric short tap
filters is presented, and it is shown that such filters can be easily
implemented by using simple arithmetic operations (e.g. addition and
multiplication). By applying the above filters, the input image is
decomposed into four bands, which are then coded by using arithmetic
coding in combination with discrete PCM coding of the lowest band and
PCM coding of higher bands. Simulation results demonstrate that by using
the method mentioned above good quality pictures can be obtained in the
range of 0.7 to 0.8 bits/pel
