This paper implements a remote image based metering(IBM) system which capture meter image, recognizes number automatically, and send the data wirelessly through PCS data network. We use existing gas/water meter and get NTSC camera image by installing small monochrome CMOS camera on the meter closely. For remote data transfer, we use SMS (short message service) that is provided by commercial PCS network. We developed DVR(digital video recorder) for capturing meter image and character recognition algorithm. In addition, hardware and software for SMS and meter selector were developed.

We suggested new PDP packaging technology using the direct joint method, which does not need an exhausting hole and tube. The advantages of this method are simple process, short process time and time panel package. To packaging, we drew the seal line of glass frit by dispenser followed by forming the lump, which provide pumping-out path during the packaging process. And, we have performed a pretreatment of glass frit to reduce the out-gases. After which, both front and rear glass plates were aligned and loaded into vacuum packaging chamber. The 4-inch monochrome AC-PDP was successfully packaged and fully emitted with brightness of 1000 $cd/m^2$. Also, glass frit properties for pretreatment condition was investigated by AES and SEM analyses.

In the luminance and chrominance signal, luminance signal creates gray images, and is capable of making each color component compatible with monochrome system. And color components of luminance and chrominance signals are useful to encode or convert the signal because they have low correlation. Each color signal has low correlation statistically, but they are not independent of one another. Therefore, this paper proposes the watermark inserting algorithm for luminance and chrominance signal in the domain of frequency founded on wavelet, considering the interdependent characteristics of color components. Therefore, it can guarantee the robustness and invisible of digital watermark.

Recently, visual object detection and tracking has become a vital role in many different applications. It spans various applications like robotics, video surveillance, and intelligent vehicle navigation. Especially, in current situation where the use of UAVs is expanding widely, detection and tracking to soot down illegal UAVs flying over the sky at airports, nuclear power plants and core facilities is becoming a very important task. The remarkable method in object tracking is correlation filter based tracker like KCF (Kernelized Correlation Filter). But it has problems related to target drift in tracking process for long-term tracking. To mitigate the target drift problem in video surveillance application, we propose a tracking method which uses KCF, adaptive thresholding and Kalman filter. In the experiment, the proposed method was verified by using monochrome video sequences which were obtained in the operational environment of UAV.

Originally, the reference white of the NTSC system used to be CIE illuminant C of 6774K. However, that of color television receiver has been adjusted to 9300K as a result of consumer preference for a very bluish white for monochrome television. Recent studies have revealed that the preferred color temperature of display white should be 3000K or 4000K higher than that of surround illuminant. Therefore it is required to classify ambient lighting source. In this paper, a efficient method that can distinguish the ambient incandescent lamp from fluorescent lamp under television viewing condition is developed using only two color sensors, yellow and cyan. Experimental results show that the proposed method is very useful for the discrimination of ambient lighting source, fluorescent of 6000K and incandescent lamp of 3000K. The system was also tested for mixture of these light sources.

The purpose of this study is to analyze the hat fashion worn by the British royal family. The research range has been limited to hats which Elizabeth II, Camilla Parker Bowles, and Kate Middleton wore from April 29, 2011 to April 11, 2014 when Kate Middleton married Windsor Prince William and became part of the royal family. The methods of the research were: previous studies and literature about the royal family were referred to, the function and types of hats were considered, and then the plasticity of the designs seen in hat fashion of the royal family were analyzed. The results are as follows: first, the shape of the hats of the British royal family: Three-dimensional shapes(84.2%) were the most frequent, the detailed shape of the hat Canotier(33.5%), Boater(12.7%) and Bowler(10.3%) had greater frequency. Second, the color of the hats were W(13.7%), Bk(10.5%), Y(9.8%), B(9.6%), YR/PB(9.4%) and RP(9.2%) color. The Color Combination is the Monochrome Color(62.3%), Analogous Color(16.1%), Accent Color(13.2%) and Complementary Color(8.4%) were most frequent. Third, the material of the hats were Felt(44.5%) and Straw(40.3%) were used most frequently. Finally, the decoration of hats were: Flowers(25.7%), String(25.0%), Ribbon(18.4%) and Feathers(17.9%) were the most common. This study can be utilized as basic data for effective styling and design ideas in the field of total fashion.

This study is intended to develop the creative and high value-added products as well as the development of diversity for jump suit for the future by analyzing the trend and feature shown in jump suit in the modern fashion. In the research methodology, the analysis was carried out over a total of 351 work pieces on jump suit among those presented in the collection of Paris, Milan, New York and London from 2006S/S to 2013F/W as well as literature review. The aesthetic features on suit jump design introduced in the modern fashion could be characterized as the following. First, both upper and lower garments are composed with a simple array of items and the stress was put on modernity feature through minimal expression technique. The feature of solid simplicity was also given with achromatic color or neutral monochrome. Second, the feminity image was emphasized with adoption of such highlighting items as detailed add-ons, tops, camisoles and blouses that stress the organically curved streamline including silhouette, material itself, crease and drape that enable the direct and indirect exposition of human body and the expression of smooth curve in human body. Third, jump suit revealed the multipurpose feature as item available for the diverse wear such as working habiliment, sports wear, uniform, office wear and evening wear, depending on the terms and conditions. Fourth, the deconstructive characteristic appeared through integration with various items, destruction of formative structure, non-structural shape, and ambiguity in wearing method.

A new integrated coding method is proposed in this study for embedding the text information including Hangul into an image. A monochrome analog image may be quantized to a few leveled digital image and be displayed on bi-leveled output devices by using halftone processing techniques. Text data are embedded on each micro pattern. Based on this concept, the encoding and the decoding algorithm are implemented and experiments are performed. As a result, the average amount of the embedded text information is more than 8 bpp (bits per pixer) in this halftone processed image converted form a $64{\times}64$ image, i.e, corresponding to 2000 characters in Hangul, or 4000 characters in alphanumeral. using this algorithm, the integrated personal record management system is implemented.

An iterative scheme for computing the three-dimensional position and the surface orientation of an opaque object from a singel shaded image is proposed. This method demonstrates that calculating the depth(distance) between the camera and the object from one shaded video image is possible. Most previous research works on $'Shape from Shading$' problem, even in the $'Photometric Stereo Method$', invoved the determination of surface orientation only. To measure the depth of an object, depth of the object, and the reflectance properties of the surface. Assuming that the object surface is uniform Lambertian the measured intensity level at a given image pixel*x,y0becomes a function of surface orientation and depth component of the object. Derived Image Irradiance Equation can`t be solved without further informations since three unknown variables(p,q and D) are in one nonlinear equation. As an additional constraints we assume that surface satisfy smoothness conditions. Then equation can be solved relaxatively using standard methods of TEX>$'Calculus of VariationTEX>$'. After checking the sensitivity of the algorithm to the errors ininput parameters, the theoretical results is tested by experiments. Three objects (plane, cylinder, and sphere)are used. Thees initial results are very encouraging since they match the theoretical calculations within 20$\%$ error in simple experiments.> error in simple experiments.

Fractal-based monochrome image coding method can be easily applied for color image compression by splitting the color image into different primary spectral channels such as RGB, YIQ or $YC_bC_r$, and encoding each channel independently According to this method, it needs to repeat the fractal coding for each channel, so it have the problem of encoding time. In this paper, a fractal-based coder for color still image is proposed which features the enhancement of compression rate and the reduction of coding time. As the result of the experiment where the proposed algorithm is applied far color images, the compression rate is enhanced by 28 : 1 above with average PSNR value $28{\sim}29[dB]$, do not lossless encoding process using JPEG. And the encoding time is reduced by maximum 11.5 %.
