On the energy leakage of discrete wavelet transform [PDF]
The energy leakage is an inherent deficiency of discrete wavelet transform (DWT) which is often ignored by researchers and practitioners. In this paper, a systematic investigation into the energy leakage is reported.

COMPARISON COMPRESSION PROPERTIES DWT WITH FB 5/3 AND FB 9/7 [PDF]
The suitability of 2-dimensional Discrete Wavelet Transform (2D DWT) as a tool in image and video compression is nowadays indisputable. Wavelet based techniques such as JPEG2000 for image compression has a lot more to offer than conventional methods in
