Squeezing of Color Image Using Dual Tree Complex Wavelet Transform Based Preliminary Plan

In this paper, we scrutinize the role of dual tree complex wavelet transform. This Dual tree complex wavelet transform (DT-CWT) is slightly short of shift invariant and directionally selective in two or rise up dimensions.The nature of multidimensional DT-CWT is non separable & dependent on the computationally expeditious, separable filter bank(SFB).This paper explains the designing of complex wavelet transform with directional properties and use of this designed form in squeezing of image. If we take the DT-CWT transform, then many of wavelet coefficients are approximately zero and this shows the intra sub-bands dependency. We further access the performance of SPIHT coding preliminary plan for coding of those coefficients. At last, In the results of proposed preliminary plan gives higher rate of squeezing and lower mean square error(MSE) compared to plan of DWT. Dual tree complex wavelet transform-SPIHT preliminary plan outperform DWT based preliminary plan at lower bit rates.
