Smoke and fire have different shapes and colours. This article suggests a fully connected system which is used two features using Adaboost algorithm for constructing a strong classifier as linear combination. We calculate the local histogram feature by gradient and bin, local binary pattern value, and projection vectors for each cell. According to the histogram magnitude, this paper applied adapted weighting value to improve the recognition rate. To preserve the local region and shape feature which has edge intensity, this paper processed the normalization sequence. For the extracted features, this paper Adaboost algorithm which makes strong classification to classify the objects. Our smoke detection system based on the proposed approach leads to higher detection accuracy than other system.

Crop Protection Products (CPPs) are a useful weapon in our fight against the pests, diseases and weeds that harm or destroy our food. To be effective CPPs need to exhibit some persistence. The consequence of this is that residues of the original material or its metabolites may remain on food and thus there is a potential for the intake of such residues. The issue of CPP residues in food is an emotional subject and is rarely debated rationally or supported by scientific facts. Media headlines like “Poison in our food” or “These days enough Pesticides (CPPs) are sprayed onto vegetables to turn you into one” are testimony to the high level of emotion that surrounds the subject of CPP residues in food. Recent surveys of consumers have indicated that more than 80 percent view CPP residues in food as a “serious hazard”. This significantly exceeds concerns over drugs, hormones in meat, nitrates in food, irradiated foods, food additives, or artificial colours.

Scandinavia consists of Norway, Sweden, Denmark, Finland, Iceland and Lapland, all linked by historical and geographical ties. In this respect, the objective of this research was to clarify the folk costume of the Scandinavia. Scandinavia many skilled handicrafts are practised, such as leatherwork, silverwork and embroidery. The most popular colours are yellow, blues, reds, greens and white. For women the costume consist of a blouse with a bodice, skirt and apron, over which is worn a jacket or shawl, accompanied by a headdress. Their accessories may be jewellery, belts, kerchiefs and separate pockets. For the men, the costume is a shirt, trousers or breeches, worn with a waistcoat and jacket, neck scarf, and topped with a hat or cap. And the Lapps, both men and women, wear woollen shirts beneath their blue-skirted tunics, and blue trousers. It is one of the most ancient of the costumes worn in western Europe, due to its total suitability to their way of life.

This article presents a reformulation of the Grey Edge framework for colour constancy. Colour constancy is the ability of a visual system to perceive objects' colours independently of their scenes' illuminants. Colour constancy algorithms try to estimate the colour of an illuminant from image values. This estimation can later be used to correct the image as though it were taken under a white illuminant. The modification presented allows the framework to incorporate image-specific filters instead of the commonly used edge detectors. A colour constancy algorithm is proposed using PCA and FastICA linear component analyses methods for the construction of such filters. The results show that the proposed method improves the accuracies of the Grey Edge framework algorithms whilst on the other hand, achieving comparable accuracies with the state-of-the-art methods, but improving their time efficiencies.

This research has been studied the influence of Song Dynasty mode upon clothes and ornaments of Korea Dynasty by Seo Gung's (徐競) 『SunWhaBongSa KoryoDoKyung』(宣和奉使高麗圖經) and in Korea Dynasty period, by Buddhist picture. The clothing of the Song Dynasty was quite reserved and conservative, fewer variations and quiter colours thus conveying a feeling of simplicity and naturalness. Their clothings were no more luxurious than the clothing of Dang Dynasty. We had read that when Seo Gung visited Korea for month, and then it is in Emperor Injong's reign(A.D. 1123). Korea women's clothes and ornaments were followed by Song dynasty's clothing pattern as much as the took notice of Korea women's clothing. Korea DoKyung showed Song women's clothing that whal clothing that whal clothing (華衣), Yuansam(圖經) were Korea women's a ceremonial dress and so, Koryo women's clothing were very influenced by Song's mode. The conclusion of the research are as follows found out that Korea women's a ceremonial dresses were similar to Song's.

This Study aims to evaluate the interior atmospheres of atrium by glass colours. For the purpose, the 1/50 scale model of one-sided atrium was made and images of interior atmospheres were pictured under clear sky conditions. And then, questionnaire surveys were conducted on K university students in department architecture engineering. The survey results were analyzed by SPSS program. Frequency and correlation analysis were performed. As results, clear glass is chosen as the most preferred glass colour in any seasons. And, green and blue glasses are preferred in the order. And then, it is revealed that the main variables affecting satisfaction of interior atmospheres are a little changed by thermal senses of seasons. These variables are "bright", "neat", "warm", "comfort", "stable", "active", "static", "elegant" and "cool" through correlation analysis.

In comparison with CCFL, LED can have more various colours. The research into BLU to raise colour reproducibility is actively proceeding by using RGB LED. On this study, Direct BLU was designed by white LED and RGB LED. According to the result of the experiment, the colour uniformity degree of BLU model using white LED is better than RGB LED BLU. On the other hand, the colour reproducibility of RGB LED BLU is better than white LED. The research showed that the uniformity of white LED is 81.7%and RGB LED is 70.01%.

천연 염재인 감 및 감나무 잎에서 추출한 염액에 견직물을 염색한 후, 매염제의 종류에 따른 K/S값, 염색성을 측정하였고, 견직물의 천연염색성과 물성을 검토한 결과 다음과 같은 결론을 얻었다. 1. 색상은 각각의 매염제에 따라 다르게 나타났으며, 후매염법이 K/S값이 크게 나타났다. 2. 감 열매가 감잎보다 짙은 남청색을 나타내었다. 3. 추출액의 농도가 높을수록 농색으로 변하였다. 4. 매염제의 종류에 따른 매염량을 측정한 결과, FeSO$_4$ 매염제가 우수한 염착량을 나타내었다. 5. 감에 의한 천연염색에 있어서 강연도와 인장강도의 물성에는 큰 변화가 없었다.

In this paper, computerized BEAM was implemented for the space domain analysis of EEG. Transformation from temporal summation to two-dimensional mappings is formed by 4 nearest point interpolaton method. Methods of representation of BEAM are two. One is dot density method which classify brain electrical potential 9 levels by dot density of gray levels and the other is colour method which classify brain electrical 12 levels by red-green colours. In this BEAM, instantaneous change and average energy distribution over any arbitrary time interval of brain electrical activity could be observed and analyzed easily. In the frequency domain, the distribution of energy spectrum of a special band can easily be distinguished normality and abnormality.
