Web22 de jul. de 2024 · The paper presents a simple, yet robust computer vision system for robot arm tracking with the use of RGB-D cameras. Tracking means to measure in real time the robot state given by three angles and with known restrictions about the robot geometry. The tracking system consists of two parts: image preprocessing and machine learning. In … WebOne simple and efficient way to precompute this table is by observing that one interval whose length is a power of 2 can be split into 2 smaller intervals. This observation translates into the following recurrence relation: r m q [ h] [ i] = m i n ( r m q [ h − 1] [ i], r m q [ h − 1] [ i + 2 h − 1]) . Below is an example of one such ...

Bounds on Half Graph Orders in Powers of Sparse Graphs

WebLet G = (V, E) be a graph on n vertices with average degree t ≥ 1 in which for every vertex v ϵ V the induced subgraph on the set of all neighbors of v is r-colorable.We show that the independence number of G is at least log t, for some absolute positive constant c.This strengthens a well-known result of Ajtai, Komlós, and Szemerédi [1]. Combining their … Websparse pseudo-random graphs. It should be stressed that the definition of pseudo-random graphs used in this study is rather restrictive and applies only to regular graphs. It seems plausible, however, that our techniques can be used to prove Hamiltonicity of almost regular graphs (i.e., graphs in which all degrees are very close to an average ...
