The communication complexity of a two-variable function f(x, y) is the number of information bits two communicators need to exchange to compute f when, initially, each knows only one of the variables....
Let x, y {0, 1} n. Persons A and B are given x and y respectively. They communicate in order that both find the Hamming Distance d(x,y). Three communication models, viz, deterministic, e-error and e-r...
Let x, y {0, 1} n. Persons A and B are given x and y respectively. They communicate in order that both find the Hamming Distance d(x,y). Three communication models, viz, deterministic, e-error and e-r...
There are several data product characterization methods to describe LiDAR data quality. Typically based on guidelines developed by government or professional societies, these techniques require the st...
We consider the classic clique (or, equivalently, the independent set) problem in two settings. In the streaming model, edges are given one by one in an adversarial order, and the algorithm aims to ou...
We develop a new technique for proving lower bounds in property testing, by showing a strong connection between testing and communication complexity. We give a simple scheme for reducing communicatio...
Measurement results of the signals emanating from both IF and LO ports of a double balanced mixer are presented, and, thus, it is shown that the linearization of the output in a down-converting mixer ...
In this paper, a joint complexity-distortion optimization approach is proposed for the real-time H.264 video encoding under the power-constrained environment. The power consumption is first translated...
Motion estimation is the most computational intensive part of H.264 video coding. The motion estimation of H.264 includes int eger motion estimation and fractional motion estimation. In this paper, a ...
This paper presents a novel B-picture coding based on block-wise adaptive motion accuracy (BAMA) with lowcomplexity motion compensation (MC). BAMA is able to adaptively select the motion accuracy for...
We consider the communication complexity of finding the longest increasing subsequence (LIS) of a string shared between two parties. We prove tight bounds for the space complexity of randomized one-p...
In this paper, a low-complexity 8x8/4x4 Adaptive Blocksize Transform (ABT) scheme is tentatively proposed for the Chinese Audio and Video coding Standard (AVS)1.In the proposed ABT scheme, an integer ...
This paper first analyses the relationship between performance and complexity of several state-of-the-art coding algorithms for high resolution videos. Based on the coding efficiency comparison under ...
Owing to the great computation complexity of the ME (motion estimation) in video coding, a lot of fast ME algorithms have been proposed in literature. Most of them are designed based on a given hypoth...
In H.264/AVC, an integer 4×4 transform is used instead of traditional float DCT transform due to its low complexity and exact reversibility. Combined with the normalization for the integerr transform...
