This paper proposes a new method of image thresholding by using cluster organization from the histogram of an image. A new similarity measure proposed is based on inter-class variance of the clusters to be merged and the intra-class variance of the new merged cluster. Experiments on practical images illustrate the effectiveness of the new method. 2006 Elsevier B.V. All rights reserved.

The feasibility of sparse signal reconstruction depends heavily on the inter-atom interference of redundant dictionary. In this paper, a semi-blindly weighted minimum variance distortionless response (SBWMVDR) is proposed to mitigate the inter-atom interference. Examples of direction of arrival estimation are presented to show that the orthogonal match pursuit (OMP) based on SBWMVDR performs be...

Face expressions are a rich source of social signals. Here we estimated the proportion of phenotypic variance in the brain response to facial expressions explained by common genetic variance captured by ∼ 500,000 single nucleotide polymorphisms. Using genomic-relationship-matrix restricted maximum likelihood (GREML), we related this global genetic variance to that in the brain response to facia...

Inter-satellite links (ISLs) can improve the performance of Global Navigation Satellite System (GNSS) in terms precise orbit determination, communication, and data-exchange capabilities. This research aimed to evaluate a simulation-based processing strategy involving exploitation ISLs determination Galileo satellites, which are not equipped with operational ISLs. The estimation process is first...

macrophomina phaseolina is an important soil-borne pathogen causing charcoal rot in many important crop plants including sesame, in iran. a total of 60 isolates of m. phaseolina were collected from the main sesame producing regions in ten provinces of iran. the genetic diversity among m. phaseolina populations was estimated using inter-simple sequence repeat (issr), focusing particularly on geo...

In order to investigation of chromosomal variation in various populations of Aegilops cylindrica from northwest of Iran, the karyotype of each populations was prepared using aceto-iron-hematoxilin staining and different chromosomal characteristics were measured. The results showed that the karyotype of these populations consisted of seven pairs of metacentric, three pairs of submetacentric and ...
