Abstract :
In this letter, a novel and computationally inexpensive analytic mean square error (mse) distortion rate (D-R) estimator for SPIHT which generates a nearly exact D-R function for the two- and three-dimensional SPIHT algorithm is presented. Utilizing our D-R estimate, we employ unequal error protection and equal error protection in order to minimize the end to end MSE distortion of the transform domain. A major contribution of this letter is the simple and extremely accurate analytical D-R model which potentially improves upon pre-existing methodologies and applications that rely on an accurate and computationally inexpensive D-R estimate.
