This paper presents an automatic sample collection method for training an adapted classifier. Classifier adaptation is an important issue for improving performance of classifier. In conventional techniques of classifier adaptation, a classifier is learned based on sample collection which is manually gathered by a generic pre-trained classifier. In this paper, we focus on minimizing manual tasks and improving performance of classifier. Our method uses background subtraction technique to collect training samples, instead of using generic classifier. The automatic sample collection method based on blob condition investigation automatically collects good samples to train the adapted classifier. Experiments demonstrate performance and computational efficiency of our method.

In recently, Is inhabiting more than 70% indoors during a day in case of company employee and ordinary people which is looking at usual business. Therefore Thermal comfort of human body about indoor temperature and air flow acting very heftily. When intestine temperature is fallen for external low temperature and air flow in winter in case enter into heated room feel comfort by effect of temperature and feel comfort or discomfort by room heating condition gradually. Therefore it is important that grasp thermal comfort about temperature and air flow in heating to keep continuous comfort in indoor dwelling. Temperature and thermal comfort factor of emotion & sensitivity image exert fair effect since heating middle although thermal comfort change greatly effect on sensation about temperature at actuality heating early. Need much study yet in vantage point of emotion & sensitivity although much study were held about thermal and comfort sensibility and when heat in existing research until now. Therefore this study is targeting that evaluate thermal comfort through introduction of estimation method by emotion & sensibility image real and synthetic sensibility about thermal environment that is becoming winter heating.

김창연 安東大學 1979 安東大學 論文集 Vol.1 No.1
시설재배에 있어서 탄산가스의 시비는 필요하며 작물체의 생육을 촉진시켜 증수를 할 수 있는 방법으로서 다음과 같은 사실들을 들 수 있겠다. 1. 시비내는 환기를 할 때까지 항상 탄산가스의 부족상태이며 심하면 탄산가스보상점 이하로 내려간다. 2. 일조가 양호할 시는 탄산가스의 공급이 더욱 필요하며 탄산가스의 부족은 강일조의 효과를 상실 한다. 3. 탄산가스 농도와 작물생육과의 관계를 보면 3,000ppm까지는 높을수록 작물생육에 효과적이다. 4. 시설내에서의 탄산가스 시여시간은 일출시 부터 환기할 때 까지에 실시하는 것이 온도환경 및 탄산가스 시용면에서 효과적 이다. 5. 서간의 탄산가스 시비는 불가능 함으로 강제 환기에 의하여 탄산가스 농도의 저하를 예방할 수 있을 것이다. 6. 탄산가스 공급원으로는 액체탄산이 경제적이고 능율적이다. 7. 실제면에서 동계의 육묘와 Tunnel 재배는 환기를 요할 온도 환경이 될 때 까지 탄산가스를 시여하여야 작물은 정상적인 생육을 할 수 있을 것이다. The growth in institution needs to be fertilized CO2 and one of the ways to increase the harvest is as follows: 1. Inside the institution carbon dioxide is always in the state of scarcity until it is ventilized, coming down to the point of compensation. 2. When the sunshine is correct the supply of carbon dioxide is of necessity and the lack of carbon dioxide lessens the effectiveness of strong sunshine. 3. In the relation of the concentration of carbon dioxide with the development of growings more than 3, 000ppm is effective to the development of growings. 4. The correct time of fertilization of carbon dioxide inside the institution is from the times of sunrise to that of ventilation, which is effective and valuable to the use of carbon dioxide and the state of temperature as well. 5. As there is no possibility of fertilizing carbon dioxide during daytime the low concentration of carbon dioxide can be prevented by compulsory ventilation. 6. The liquid carbon dioxide is economical and effective as a source of carbon dioxide. 7. In growing saplings and in the way of Tunnel Growth in winter, in fact, carbon dioxide should be fertilized until the temperature of the inside needs to be ventilized.
