Shadows often confound algorithms designed to solve computer vision tasks such as image segmentation, object detection and tracking. In this paper, a shadow detection and removal technique is proposed. The method requires no camera calibration or other a priori information regarding the scene. Support vector machines are used to identify shadow boundaries based on their boundary properties. Thi...

Yousif Department of Mathematics and Computer Science, Faculty of Science, Beirut Arab University, Lebanon Email: [email protected] Abstract: Arabic text classification methods have emerged as a natural result of the existence of a massive amount of varied textual information (written in Arabic language) on the web. In most text classification processes, featu...

In recent years, many probabilistic algorithms (i.e., algorithms that can toss coins) that run in polynomial time have been discovered for problems with no known deterministic polynomial time algorithms. Perhaps the most famous example is the problem of testing large (say, 100 digit) numbers for primality. Even for problems which are known to have deterministic polynomial time algorithms, these...

Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of SL(2)×SU(2)×U(1)x U(1)×U(1) quotient CFTs. Uncharged incoming wavefunctions from the “whiskers” of the extended universe can be fully reflected if and only if a big bang/crunch curvature singularity, from which they are scattered, exists. Extend...

BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

Sida is a pantropical weed that can be annual or perennial. Several species have been identified in Indonesia. cordifolia, S. rhombifolia, alnifolia, rhomboidea, acuta, glutinosa, and mysorensis were chosen for this study because they are representative of the extensively spread This aims to update taxonomic information on genus A phenogram was created using data derived from scoring 70 morphol...
