....lossless first order entropy, simulations are carried out by varying the size of the transform. Lossless pyramid structured coding schemes based on various sizes of ULWHT are also compared with other lossless pyramid structured coding schemes such as Hierarchy Embedded Differential Image (HEDI) [3] and Reduced Difference Pyramid (RDP) 11] 2. Properties of rounding operations Floor and ceiling operations are denoted by and , which take the nearest inferior integer value and the nearest superior one, respectively. Their basic properties are summarized. ....
....to the S Transform. The results are also compared, in terms of the total lossless first order entropy, with other mean based lossless pyramid structured coding schemes such as HEDI and RDP. In this simulation, HEDI CM2 is used because it was empirically found to yield the lowest entropy in [3]. Note that HEDI CM2 and RDP have the same performance as reported in [2] The simulation results are tabulated in Table. 1. Employing 2 2 and 2 2 2 2 block sizes performs slightly better than HEDI CM2 and RDP on the majority of test images. The smallest size ULWHT (i.e. S Transform) ....

Rounding Transform and Its Application for Lossless Pyramid.. - Co Di Ng (Correct)
.... coding [1,2] is usually used for lossless image compression, pyramid structured coding is still an attractive solution due to the progressive transmission [3,4] Two pyramid structured coding methods have been studied in depth : the sub sample based methods [5 7] and the mean based methods [8 11]. The sub sample based methods mainly transmit difference images between two successive levels of the sub sample pyramid. The mean based methods such as the S Transform [8 10] and the hierarchy embedded differential image (HEDI) 11] construct a mean based pyramid by rounding the mean of the ....

The mean based methods such as the S Transform [8 10] and the hierarchy embedded differential image (HEDI) [11] construct a mean based pyramid by rounding the mean of the non overlapping block and then generating the differences between neighboring nodes of the mean pyramid to achieve good lossless compression. In recent works [12,13] more efficient compression was found using the S Transform based ....
