This paper discusses a new method of hiding ASCII characters based on match between bit value of the randomly selected image pixel and the data bits. Bit positions in the higher nibbles of the cover image are used for data hiding at a position indicated using a 2-bit code. Simulation results on Lena, Gibbon and Cat images [1] for hiding a large set of ASCII text characters indicate that suggest...

Oracle-bone inscriptions are pioneer mature characters in China, named as china archaic “record-base”. Because oracle-bone was not smoothness, and went through thousands years, its damage is very grievous, many spots covered up pristine inscriptions. In the paper we analyse the characteristic of rubbings and try wavelet transform for removing noise of different defective rubbings of oracle-bone...

We develop, analyze and experiment with a new tool, called madmx, which extracts frequent motifs, possibly including don’t care characters, from biological sequences. We introduce density, a simple and flexible measure for bounding the number of don’t cares in a motif, defined as the ratio of solid (i.e., different from don’t care) characters to the total length of the motif. By extracting only...

Konstantinos Chorianopoulos Technical University of Crete Department of Electronic and Computer Engineering Chania 731 00 GREECE [email protected] Abstract Animated characters have been a popular research theme, but the respective desktop applications have not been well-received by end-users. The objective of this study was to evaluate the use of an animated character for presenting information ...

Characters are carefully designed shapes incorporating both the design ideas of a skilled character designer [1] and the rules related to visual appearance. The visual appearance of printed characters is the result of many interacting factors: the design intentions of the type designer, the artistic creation of the different character shapes as typeface masters, the font industrialization, rend...

A segmentation-free approach to OCR is presented as part of a knowledge-based word interpretation model. This new method is based on the recognition of subgraphs homeomorphic to previously defined prototypes of characters [16]. Gaps are identified as potential parts of characters by implementing a variant of the notion of relative neighborhood used in computational perception. In the system, ea...

What are the natural features of hand-written characters and how to arrive at them automatically? We apply independent components analysis on hand-written characters. Independent components analysis extracts the underlying statistically independent signals from a mixure of them. We expect strokes to be the independent components of handwritten characters. Our findings show that stroke-like feat...

Previous studies suggest that writing helps reading development in Chinese in both first and second language settings by enabling higher‐quality orthographic representation of the characters. This study investigated the comparative effectiveness of reading, animation, and writing in developing foreign language learners’ orthographic knowledge of Chinese and found that, for learners with existin...

Engraved characters are usually a limitation for character recognition, as their extraction is difficult due to the small contrast with the background. Nevertheless, they are present in several industrial applications and their handling may be convenient for special tasks such as traceability or quality control. We propose here an entire system from acquisition to character recognition by consi...
