We conduct a comparative study between GAs and the enumeration method and give relevant analysis in the end of this paper.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122113250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, histogram of oriented gradient (HOG) is a quite popular algorithm for person detection in visible imagery. We implement the pedestrian detection in infrared imagery with this algorithm by adjusting the parameters. Simultaneously, we have increased some other geometric characteristics, such as mean contrast, which is used as features for the detection. After analyzing the property of the infrared imagery, which is designed to meet the shortfall of the HOG in infrared imagery, the combined vectors are fed to a linear SVM for object/non-object classification and we get the detector at the same time. After that, the detection window is scanned across the image at multiple positions and scales, which is followed by the combination of the overlapping detections. At last, a pedestrian is described by a final detection, and we have detected the pedestrians in the thermal imagery. Experimental results with OSU Thermal Pedestrian Database are reported to demonstrate the excellent performance of our algorithms.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117215754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that emotion elicited after learning can affect memory consolidation. However, many prior studies were based on animal studies. Furthermore, it is unclear whether the effect of emotion can extend to reconsolidation of different aspects of memory for an event. This study therefore examined the effect of post-learning emotion, elicited by video clips, on reconsolidation of memory for item memory and source memory for Chinese words. On day 1 participant learned a list of neutral, positive and negative Chinese words, and took immediate test of free recall. On day 2 (24 hours after the session in day 1) they returned to the laboratory, took a test of free recall for memory reactivation, and then watched a 3-min neutral, positive, or negative video clips for emotion elicitation. On day 3 (24 hours after the session in day 2), they returned to the laboratory and took a test of cued-recall. The results showed that whether negative nor positive, that was elicited after reactivation of memory through the paradigm of recalling, could affect the reconsolidation of both item memory and source memory. However, that item memory for emotional words were significantly better than for neutral words, whereas source memory for emotional words did not significantly differ from that for neutral words. This finding indicating that emotion has differential effects on item memory and source memory.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128317830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
