The discrete wavelet transform (DWT) plays a central role in a number of signal and image processing applications. The lifting scheme is a new algorithm proposed for the implementation of the wavelet transform. It can reduce the computational complexity of DWT involved with the convolution implementation. The lifting scheme consists of the following three steps Split, Predict and Update step. In conventional Lifting Scheme based DWT, complete image is divided into two parts that is even and odd image pixels. One even and one odd image pixel leads to PREDICT and UPDATE steps. In Piecewise Lifti...
