Optimized fixed point implementation of a local stereo matching algorithm onto C66x DSP
Proceedings of the 2014 Conference on Design and Architectures for Signal and Image Processing, 2014 Stereo matching techniques aim at reconstructing disparity maps from a pair of images. The use of stereo matching techniques in embedded systems is very challenging due to the complexity of the state-of-the-art algorithms.

Greedy algorithms for dirac mixture approximation of arbitrary probability density functions
2007 46th IEEE Conference on Decision and Control, 2007 Greedy procedures for suboptimal Dirac mixture approximation of an arbitrary probability density function are proposed, which approach the desired density by sequentially adding one component at a time. Similar to the batch solutions proposed earlier, a distance measure between the corresponding cumulative distributions is minimized by selecting the ...

A consistent approximation of the total perimeter functional for topology optimization algorithms [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2022 This article revolves around the total perimeter functional, one particular version of the perimeter of a shape Ω contained in a fixed computational domainDmeasuring the total area of its boundary∂Ω, as opposed to its relative perimeter, which only takes into account the regions of∂Ω strictly insideD.

Efficient by Precision Algorithms for Approximating Functions from Some Classes by Fourier Series
Кібернетика та комп'ютерні технологіїIntroduction. The problem of approximation can be considered as the basis of computational methods, namely, the approximation of individual functions or classes of functions by functions that are in some sense simpler than the functions being ...

Randomized Strategies for Robust Combinatorial Optimization
, 2018 In this paper, we study the following robust optimization problem. Given an independence system and candidate objective functions, we choose an independent set, and then an adversary chooses one objective function, knowing our choice. Our goal is to find

Algorithms for DC Programming via Polyhedral Approximations of Convex Functions
, 2023 There is an existing exact algorithm that solves DC programming problems if one component of the DC function is polyhedral convex (Loehne, Wagner, 2017). Motivated by this, first, we consider two cutting-plane algorithms for generating an $ε$-polyhedral underestimator of a convex function g.
