This problem is formulated as a manifold perception algorithm such that the precision position of a mobile robot is evaluated based on the distance from an obstacle, critical features or signs of surroundings and the depth of its surrounding images. We propose to accurately localize the position of a mobile robot using an algorithm that fusing the local plane coordinates information getting from laser ranging and space visual information represented by features of a depth image with variational weights, by which the local distance information of laser ranging and depth vision information are relatively complemented. First, we utilize EKF algorithm on the data gathered by laser to get coarse location of a robot, then open RGB-D camera to capture depth images and we extract SURF features of images, when the features are matched with training examples, the RANSAC algorithm is used to check consistency of spatial structures. Finally, extensive experiments show that our fusion method has significantly improved location results of accuracy compared with the results using either EKF on laser data or SURF features matching on depth images. Especially, experiments with variational fusion weights demonstrated that with this method our robot was capable of accomplishing self-location precisely in real time.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125685887","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}

Hedonic well-being refers to one's overall positive affective experiences, while eudaimonic well-being is related to having a meaningful and noble purpose for life. While people are striving to have a happy and meaningful life, their motivations can be influenced by socio-economic conditions and contexts. In this study, we analyzed words frequencies in the Google Books corpus to measure the changing needs for eudaimonic and hedonic well-being and their relationships with economic growth. Results show that the frequencies of words related to hedonic well-being decrease while those related to eudaimonic well-being increase over the years. Furthermore, when people are poor, their motivation for hedonic well-being is relatively high. The hedonic motivational strength dramatically decreases and becomes stable when income reaches at a certain level. In contrast, people have relatively low motivation for eudaimonic well-being when they are poor. The eudaimonic motivational strength dramatically increases and becomes stable when income reaches at a certain level. Our study demonstrates an example of measuring subjective well-being through analysis of digital media.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128729009","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}

The goal of this work is to build an Automatic Emotion Variation Detection (AEVD) system to determine each emotional salient segment in continuous speech. We focus on emotion detection in angry-neutral speech, which is common in recent studies of AEVD. This study proposes a novel framework for AEVD using Multi-scaled Sliding Window (MSW-AEVD) to assign an emotion class to each window-shift by fusion decisions of all the sliding windows containing the shift. Firstly, sliding window with fixed-length is introduced as the basic procedure, in which several different fusion methods are investigated. Then multi-scaled sliding window is employed to support multi-classifiers with different timescale features, in which another two fusion strategies are provided. Finally, a postprocessing is applied to refine the final outputs. Performance evaluation is carried out on the public Berlin database EMO-DB. Our experimental results show that proposed MSW-AEVD significantly outperforms the traditional HMM-based AEVD.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128745268","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}
