Abstract We introduce a greedy algorithm optimizing arrangements of lines with respect to property. apply this the case simpliciality: it recovers all known simplicial in very short time and also produces yet unknown arrangement 35 lines. compute (certainly incomplete) database combinatorially complex hyperplanes up 50 Surprisingly, contains several examples whose matroids have an infinite spac...

Plane segmentation is an important step in feature extraction and 3D modeling from light detection and ranging (LiDAR) point cloud. The accuracy and speed of plane segmentation are two issues difficult to balance, particularly when dealing with a massive point cloud with millions of points. A fast and easy-to-implement algorithm of plane segmentation based on cross-line element growth (CLEG) is...

This paper proposes an effective color-difference-based (ECDB) interpolation algorithm for color filter array (CFA) image demosaicking. A CFA image consists of a set of spectrally selective filters which are arranged in an interleaved pattern such that only one color component is sampled at each pixel location. To improve the quality of reconstructed fullcolor images from CFA images, the ECDB a...

The use of commercial flowsheeting programs enables straight-forward rigorous, but user hidden, mathematical formulations chemical processes. optimization such black-box models is a challenging task due to nonconvexity, absence accurate derivatives, and simulation convergence failures which can prevent classical procedures from continuing the search. Here, we present an framework based on exten...

This paper focuses on the evaluation of an ideal midsagittal plane (iMSP) extraction algorithm. The algorithm was developed for capturing the iMSP from 3D normal and pathological neural images. The main challenges are the drastic structural asymmetry that often exists in pathological brains, and the sparse, nonisotropic data sampling that is common in clinical practice. A simple edge-based, cro...

Energy efficiency is considered as a critical requirement for wireless sensor networks. As more wireless sensor nodes are equipped with multi-cores, there are emerging needs for energy-efficient real-time scheduling algorithms. The T-L plane-based scheme is known to be an optimal global scheduling technique for periodic real-time tasks on multi-cores. Unfortunately, there has been a scarcity of...
