The results are also compared with the standalone JPEG, JPEG2000 and SPIHT algorithms, as shown in figure 2 and figure 3.
it is clearly evident from the figure that reconstructed different images show better quality of the image for proposed scheme (figure 4) compared to that of SPIHT scheme (figure 4 (d)) as the PSNR values achievable for proposed scheme is much higher than that of SPIHT scheme.
The Table 4 results show that the SPIHT scheme provides moderate or low complexity level.
The Modified SPIHT algorithm for multiwavelet differs from the ordinary SPIHT algorithm by the way in which the subsets are partitioned and significant information is conveyed which is shown in a tree structure, called spatial orientation tree, defines the spatial relationship on the hierarchical pyramid, how spatial orientation tree is defined for multiwavelet coefficients.
In order to quantitatively examine the performance of these compression algorithms on UWB signals, the JPEG2000 and SPIHT algorithms are applied to UWB signals used for breast cancer classification.
Este metodo establece valores de la tasa de compresion para ciertos niveles de calidad en las tres tecnicas utilizadas bajo la norma DICOM: JPEG, SPIHT y JPEG2000, utilizando imagenes comprimidas en JPEG, para luego ser procesadas en JPEG2000, con la misma calidad de imagen.
Lossless compression of volumetric medical images with improved three-dimensional SPIHT algorithm.
The quantization method used to generate the result in this paper is the SPIHT [15].
Pallam shetty (2011) entropy coding by EBCOT and SPIHT is better than other methods because whole input stream is encoded as one code after sequential check of all input symbols.
For encoding the base color U, the 9 by 7 wavelet filter and SPIHT coding are used.
With an extension of EZW, SPIHT algorithm was introduced by Amir and Pearlman in (6).
The former have been researched and applied widely, as for example EZW, SPIHT and SPECK for volumetric medical data [6]-[9].
