As background significantly affects measurement accuracy and a detection limit in determination of the trace amounts of uranium, it is necessary to determine the impurities in the Lexan detector film for single particle measurements by thermal ionization mass spectrometry coupled with fission track technique (FT-TIMS). We have prepared various micro sizes of the blank Lexan detector film using a micromanipulation technique for uranium measurements by TIMS. Few tens of fg of uranium background with no remarkable dependency on the film sizes were observed in the blank Lexan films with the sizes from $50{\times}50\;{\mu}m^2$ to $300{\times}300\;{\mu}m^2$. Based on the determination of the uranium background in the Lexan film, any background correction is necessary in the isotopic analysis of a uranium single particle with micron sizes when the particle bearing Lexan film is dissected with less than $300{\times}300\;{\mu}m^2$ size. The isotopic analysis of a uranium particle in U030 standard material using TIMS was carried out to verify the applicability of the Lexan film to the single particle analysis with high accuracy and precision.

This study investigated the colors of the costumes and backgrounds of characters in the films "Thirst" and "Mother" from an integrated perspective. As a study method, ten scenes per film, which contained the characters and backgrounds from the start to the end of the DVDs of "Thirst" and "Mother" were examined. For integrated color analysis of the costumes and backgrounds, the colors of the captured scenes were simplified to extract representative colors, and then color palettes were presented according to the ratio of area. The colors of costumes were analyzed by recognition through the eyes based on the I.R.I. Hue and Tone 120. Furthermore, the color images of the two films were analyzed using the I.R.I. adjective image scales and the I.R.I. color image scales. The colors of the film "Thirst" were generally low in brightness and high in chroma. They are characterized by dark, gloomy toned-down background in the first half, highly chromatic vivid background in the second half, and the contrast of purple blue colors and red colors. The colors of the film "Mother" are characterized by complementary colors between background and costume colors, and various tones of blue and green colors. From the aspect of color tones, they were relatively high in brightness compared to the film "Thirst" but low in chroma. On the I.R.I. adjective image scale, contrasting adjectives were extracted simultaneously from the film "Thirst" as the adjectives were evenly distributed at hard, dynamic and static, whereas the adjectives extracted from the film "Mother" were distributed at hard and statistic. On the I.R.I. color image scale, both films were located at hard, but the film "Thirst" was located at dynamic whereas the film "Mother" was located at static.

Korean film "Swiri"(1999) as well as a popular film is the first Korean blockbuster Film. In addition, the number of viewers is very common in Korea a large ripple effect that Korea film "Swiri" in his works were selected to act as a hero and contextual significance confrontation between the two figures through the symbolic analysis of clothing styles and colors Analyzing the meaning of space and a scene in the background with the colorful costumes and would like to study. In detail, the film's central character theme and image suggesting that dramatic reversal the character's personality through the clothes I was expressed through clothing styles and colors were analyzed with symbolism. Korean film "Swiri" the film's DVD player application from the situation or story that is considered to be important psychological conflicts selected twenty-seven screens in the study were collected still images. Data collected for the effect of color contrast and color analysis technical. The center of the video footage, the film's main characters costumes and background colors of the space was to examine the significance and symbolism.

The style of a film is the element that makes audience realize director's purpose directly. As the film's spectacular background have became important it's hard to find non-wide screen film, and audience and theaters are very familiar to 1.85:1 film ratio and even wider. Nevertheless, did not follow this trend but to chose narrow film ratio and shallow focus. This film, of which the background is Nazi's concentration camp, does not allow audience to catch more information than main character Saul. It's because the director aims to make audience Saul's position in the film. This paper discuss how the style of reflects the director's intention.

In this paper, we propose an effective method to extract background components in automated vision inspection system for polarized film used in TFT LCD display panels. The test image signals are typically composed of three components such as ununiform background, random noises and target defect signals. It is important to analyze the background signal for accurate extraction of defect components. Two dimensional continuous wavelets with first derivative gaussian is used. This methods can be applied for reliable extraction of defect signal by elimination of the background signal from the original image. The proposed method outperforms over conventional FFT methods.

In 2013, Academy Award for Best Animated Short Film was granted to Walt Disney's short animation, (2012). With various aspects of its excellence, I focus on the very effective use of digital lightings and underscores for storytelling as its success factors. In this respect, this paper aims at analyzing the roles of the visual factors, especially tone, contrast, etc. created by lightings, and audio factors, especially underscores, in the film's story development. I find that can be characterized by the well-built story structure with distinct three acts. The main stream of the story is expressed with the overall mood that is created by the fine adjustments of brightness of the main light, and contrast. And the direction and the intensity of the lighting successfully describe the emotions of the characters in each scene. In addition, I find that properly chosen and positioned underscores make the development of the story more dynamic and more harmonized.

This paper proposes a new method for image composition which estimates the rotation angle of human hand and uses the reserved image in real-time camera images. First, we capture a background image and extract a interesting region by background subtraction. Next, we estimate the skin region from the interesting region and calculate the rotation angle of estimated skin region using PCA(Principal Components Analysis). Finally, we composite the reserved image for the calculated rotation angle in camera images. The proposed method can be applied to control the 3D avatar for marker-less augmented reality.

Purpose: Basic design of virtual colored overlay, film overlay, colored lenses and colored glasses for people with Scotopic Sensitivity Syndrome. Methods: I calculated sRGB and RGB values of the overlays from measured data. I evaluated the relationship between the combinational chromaticities composed of Galaxy Tab white background and film overlays and the chromaticities of pure film overlays. Results: Implementable sRGB and RGB values of the overlays is calculated. The chromaticities of film overlays are different from them with white paper background and them with Galaxy Tab's white background, but showed a certain relationship between them. Light transmittances of Intuitive Overlay are the most (59%-79%) among them and average light reflectance of Reading Ruler is least(8%). Conclusions: The sRGB values and the RGB values are directly applicable to implement assistive tools and the light transmittances are used to calculate ${\alpha}$, transparency of virtual overlay in IT devices. It is recommended to consider the chromaticity of white color in implementing virtual colored overlay in the case which the chromaticity is considerably different to theoretical chromaticity of white color.

In this paper, we propose the algorithm for making panoramic background and object tacking using pan-tilt-zoom camera. We draw an analogy relation between images for cylinder projection, rearrange of images, stitching, and blending. We can then make the panoramic background, and can track the object use the panoramic background. After generated the background, the proposed algorithm tracks the moving object. Therefore it can detect the wide area, and it tracks the object continuously. So the proposed algorithm is able to use at wide area to detect and track the object.
