High-resolution infinite level uniform scalar quantizers are considered for the two cases when cell midpoints and cell centroids are used as reconstruction levels. First, it is shown that asymptotically, as the cell size goes to zero, midpoints induce the same MSE as centroids. Hence, they ...
In this paper, the design procedure of the piecewise uniform scalar quantizer having segments with widths that form a geometric progression is presented. The proposed quantizer design optimization for the Laplacian source of the unit variance is performed by optimizing the distortion in respect to the...

Another, less restrictive class of uniform quantizers is called uniform threshold quantizers, whereby the thresholds are set to be uniformly spaced and the quantizer levels are allowed their optimum points of the centroids of the intervals. The principles that follow are true for both kinds of uni...
