paraschistura prokofiev, 2009 is a newly described genus based on osteological characters, but detailed information for all species of the genus is not available. to describe osteological characteristics of the endemic species of paraschistura nielseni , twelve specimens were collected from the shapur river of persis basin which drains to the persian gulf and their osteological characteristics ...

Plant leaf detection and segmentation are challenging tasks for in-situ plant image analysis. Here, a novel scheme is proposed to detect individual leaves accurately determine shapes in natural scenes. A skeleton-extraction method was developed by analysing local features of skeleton pixels. Approximate positions were determined according the main skeleton. Sub-images containing only single tar...

A mathematical morphology based approach for color image indexing is explored in this paper. Morphological signatures are powerful descriptions of the image content in the framework of mathematical morphology. A morphological signature (either a pattern spectrum or a differential morphological profile) is defined as a series of morphological operations (namely openings and closings) considering...

The alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. Each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. The p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. The skeleton be considered as a r...

Parallel programming is very interesting today. Many employment can be individuate for this technology. For example in physical processes modeling or in the simulation of cardiac dynamics. It is clear that heavy load computational applications are appropriate for test parallel programming and parallel architectures. In the Polytechnic of Bari our research group, cooperating with Italian Space A...

Existing skeletonization methods operate directly on the binary image ignoring the gray-level information. In this paper we propose a new method for the skeletonization of handwritten characters that uses graylevel information and capitalizes on their elongated pattern properties. The method controls the development of the skeleton while iteratively binarizing the gray-level image. Two types of...

To address the difficulty of locating picking point a tea sprout during intelligent automatic famous tea, this study proposes method to obtain information on basis Shi-Tomasi algorithm. This can rapidly identify sprout’s and its coordinates. Images sprouts in garden were collected, G-B component was segmented using Otsu The region interest set with lowest contour as center. characteristics buds...

The paper describes a newly presented hybrid method for high efficiency in script image feature extraction. The recognition rate was about 82% for very large number of scripts per class. However, it has reached even 100% in some cases with a smaller number of scripts per class. The system contains two projectionbased methods for image characteristics extraction presented by very simple feature ...

Natural visual images are typically composed of multiple objects, which need to be segregated from each other and from the background. The visual system has evolved to capture a great variety of cues that allow a meaningful segmentation of the visual input. One of these cues is connectedness. Connected image regions are likely to belong to a single visual object, whereas disconnected image regi...

formerly the turkmenian stone loach was the only member of the genus metaschistura based on osteological characters. but recently, it is placed in the genus paraschistura based on mtdna coi data. to provide a detailed description of the osteological characteristics of paraschistura cristata (berg 1898), ten specimens of p. cristata were collected from the hari river basin in iran and their oste...
