This study presents an experimental method of determining a two-dimensional image of the gas temperature in atmospheric DC glow corona by spectral imaging. A steady-state glow corona discharge as a partial discharge was generated by applying positive DC voltage to rod-to-plane electrode in synthetic air (N2:79%, O2:21%) at atmospheric pressure. Spectral imaging displays an image, and measures its...
Two types of hosts, 1 and 2, in which benzocrown ether units were conjugated to monocationic pyridinium and dicationic bipyridinium units, respectively, have been prepared. 1 and 2 exhibited color-to-colorless changes induced by alkali metal ion, associated with blue shift of their intramolecular charge transfer (ICT) absorptions due to the formation of a 1:1 host-guest inclusion complex. 3 and 4...
In this paper, in order to realize the image enlargement with high performance, we propose a new enlargement method, which restores high-frequency components lost in the interpolation-based methods, by using high-frequency estimation. The estimation is based on the eigenspace method proposed by Amano et al.. The proposed enlargement method can generate lost high-frequency components by using pairs...
Character recognition is a classical issue which has been devoted by a lot of researchers. Making character recognition system more widely available in natural scene images might open up interesting possibility to use as an input interface of characters and an annotation method for images. Nevertheless, it is still difficult to recognize all sorts of fonts including decorated characters such as characters...
We propose a novel background and foreground estimation algorithm in MAP-MRF approach for binarization of degraded document image. In the proposed algorithm, an assumption that background whiteness and foreground blackness is not employed differently from the conventional algorithm, and we employ characters' irregularities based on local statistics. This makes the method possible to apply to the image...
Image completion is a method for completing missing parts caused by the removal of foreground or background elements from an image in a plausible way. In the conventional method, the missing parts of an image are completed by optimizing the objective function, which is defined based on pattern similarity between the missing region and the rest of the image (data region). However, the resultant image...

Decorative characters are widely used in various scenes. Practical optical character reader is required to deal with not only common fonts but also complex designed fonts. However, since the appearances of decorated characters are complicated, most general character recognition systems cannot give good performances on decorated characters. In this paper, an algorithm that can extract character's essential...
Summary. We previously identified a 175 kDa polypeptide in Lilium longiflorum germinating pollen using a monoclonal antibody raised against myosin II heavy chain from Physarum polycephalum. In the present study, the equivalent polypeptide was also found in cultured tobacco BY-2 cells. Analysis of the amino acid sequences revealed that the 175 kDa polypeptide is clathrin heavy chain and not myosin...
