ABSTRACT: By using wavelet packet, the image can be decomposed both in the low frequency part and high
frequency part. Wavelet packet analysis technology has been used in image processing as a new time-frequency
analysis tool. In this paper, by using wavelet packet to decompose image and proper threshold to process the
coefficients of the wavelet ...
