Image Coding with Contourlet/Wavelet Transforms and SPIHT Algorithm - An Experimental Study
We investigate the error resilience of the image coded with the wavelet/contourlet transform and the SPIHT algorithm. We experimentally verify the behaviour for two scenarios: partial decoding (as with scalable coding/transmission) and random sequence errors (as with transmission errors). Using a number of image quality metrics, we analyze the overall performance, as well as differences between each transform. We observe that error difference between transforms varies with length of decoded sequence.
