A Novel Hybrid Approach Based On A Chaotic Cloud Gravitational Search Algorithm To Complicated Image Template Matching, Weijia Cui, Yuzhu He
A Novel Hybrid Approach Based On A Chaotic Cloud Gravitational Search Algorithm To Complicated Image Template Matching, Weijia Cui, Yuzhu He
Turkish Journal of Electrical Engineering and Computer Sciences
Template matching is the process of accurately extracting the interesting regions in a source image according to reference templates. In this paper, the gravitational search algorithm (GSA) is employed as a novel search strategy for template matching. However, the basic GSA is easily trapped in a local optimum and has a poor exploitation ability. In this paper, to enhance the optimization performance of GSA, a novel cross-search strategy based on chaotic global search (CGS) and cloud local search (CLS) is incorporated into GSA. The new variant is named chaotic cloud GSA (CCGSA). CGS makes full use of the ergodicity of …

Microhabitat Partitioning Of Closely Related Sarawak (Malaysian Borneo)Frog Species Previously Assigned To The Genus Hylarana (Amphibia: Anura), Ramlah Zainudin, Badrul Munir Md Zain, Norhayati Ahmad, Shukor Mohd Nor
Turkish Journal of Zoology
Microhabitats play an important role as resources that are partitioned between phylogenetically related or ecologically similar species (i.e., a guild). This hypothesis was tested by first elucidating phylogenetically closed Sarawak frog species via DNA sequencing of the 16S rRNA mitochondrial DNA gene, and later determining their microhabitat guild and partitioning via nonmetric dimensional scale. Mitochondrial 16S gene revealed 5 monophyletic groups consisting of Hylarana erythraea + Amnirana nicobariensis, Chalcorana raniceps, Abavorana luctuosa, Pulchrana signata + P. picturata, and P. baramica + P. glandulosa + P. laterimaculata. On the other hand, microhabitat utilization grouped the frogs into 5 ecological guilds consisting …
