matlab simulation in Territories

Matlab simulation in Territories:

Matlab simulation in Territories The lifting step scheme to decompose the test images with four levels of decomposition in all three dimensions.matlab simulation in Territories We created a layered output bit-stream whose reconstruction quality progressively improves up to lossless reconstruction. For the case of, we employed four levels of decomposition in all three dimensions.

We losslessly coded the sub-bands using code-blocks and precincts to group coefficients describing the same region at the same decompositionmatlab simulation in Territories level. The dimensions of the code-blocks and precincts were selected to match the dimensions of the code-cubes employed in our proposed method, as tabulated in column. For each test sequence,

we created a layered output bit-stream whose reconstruction quality progressively improves up to lossless reconstruction. We employed the method to define a VOI according to the VOI coordinates tabulated in column In the case of the GSB method, we matlab simulation in Territoriesempirically selected the scaling value that produces the VOI quality most similar to the VOI quality attained by our proposed method, while still allowing for decoding of partial background information at different bit-rates.

The selected scaling values for the test sequences are tabulated in column values of the VOI and background of the test sequences after decoding at a variety matlab simulation in Territories of bit-rates It can be seen that, for all test sequences, the proposed method achieves higher PSNR values for the VOI and background than those achieved by the GSB method.

Even though the GSB method allows for decoding matlab simulation in Territories of partial background information in conjunction with the VOI, this partial information is determined by manually selecting a scaling value for the background coefficients, which may affect the coding performance.
