Camera-based character recognition has a possibility to realize a variety of applications and has been paid attention. However, character images are often taken from different angles and characters tend to be distorted. In such a case, recognition accuracy becomes worse. Therefore, we must find some methods to deal with this problem. In this paper, we experimentally evaluate some affine-invaria...

the expansion of grey- black pottery tradition in the iranian plateau, on the basis of iron age theory of cultural dynamism, was emerged by the end of the 2nd millennium bc. such a pottery tradition is regarded as a cultural sign to point migrants who entered in the iranian plateau from the northern outside of caucasus the major. according to the theory, the migrants passed the river valley of ...

This paper presents the analysis of similarity between local decisions, in the process of alphanumeric hand-prints classification. From the analysis of local characteristics of handprinted numerals and characters, extracted by a zoning method, the set of classification decisions is obtained and the similarity among them is investigated. For this purpose the Similarity Index is used, which is an...

The synthesis of existing fonts with characters represented by parametrized structure elements requires determining a set of font-specific global and local parameters. Parameters comprise, for example, the widths of vertical stems, horizontal bars and curved elements, the spacing between vertical stems, the relative position of the junction between arches and vertical bars and serif measures. T...

This paper presents a novel local threshold algorithm for the binarization of document images. Stroke width of handwritten and printed characters in documents is utilized as the shape feature. As a result, in addition to the intensity analysis, the proposed algorithm introduces the stroke width as shape information into local thresholding. Experimental results for both synthetic and practical d...

abstract more than %90 of natural silk in world is produced by means of mulberry silkworm (bombyx mori l.). therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. for this purpose, an experiment was conducted with five mulberry varieties (kenmochi, kairyonase, ichinose, shinichinose and local varieties) during two seaso...

Here in this article, there is an attempt to pay attention to the importance of people characters (traditional and civil) in the improvement of urban management due to the sustainable urban development. The deduction of this article in that people characters can play an important role in the process of developing and improving the operation of urban management by paving the way far participatio...

How are Chinese characters recognized and represented in the brain of skilled readers? Functional MRI fast adaptation technique was used to address this question. We found that neural adaptation effects were limited to identical characters in bilateral ventral visual system while no activation reduction was observed for partially overlapping characters regardless of the spatial location of the ...

This paper presents a selective local thresholding method of a camera based document image for applying character segmentation. It is very difficult to binarize a camera based document image due to inconsistent lighting condition. It makes difficulties of character extraction and recognition. A selective local thresholding method in character region can reduce illumination effect and extract pr...
