Abstract :
This paper introduces group testing for wavelet packets (GTWP), a novel embedded image compression algorithm based on wavelet packets and group testing. This algorithm extends the group testing for wavelets (GTW) algorithm to handle wavelet packets. Like its predecessor, GTWP obtains good compression performance without the use of arithmetic coding. It also shows that the group testing methodology is very flexible and can be applied in many different circumstances
