This research examines the performance of sliding window, hidden Markov Model (HMM) and conditional random field (CRF) as the first layer classifier to segment the input video into a sequence of motion primitive label. The second layer classifier is stochastic error-correcting context-free grammar, built based on dance master knowledge, to parse the sequence of labels, builds a parse tree, and computes the accumulated dance score. The dataset for this research is captured using one Kinect camera. The training dataset is: 212 samples of 12 motion primitive samples and seven videos of Pendet dance performance. From 5-fold cross-validation, accuracy of sliding window, HMM, and CRF are 0.63, 0.79, and 0.86 respectively. This result shows that CRF achieves higher performance as a dance motion primitive recognizer than HMM as proposed by [1]. The CRF model achieves 0.88 of accuracy when motion feature is all skeleton joint angular coordinates as proposed by [2] but increases to 0.93 if the motion feature is only upper-body joint coordinates. Stochastic error-correcting context-free grammar is chosen as dance choreography model. The experiment using synthetic sequence label with cost factor ci=1 and error-sequence labels up to 50 percent shows the grammar can tolerate the input label sequence error up to 25 percent. The experiment using Pendet dance performances show that the average dance score is 79.3. The low dance score is due to several factors including: dance skill variation, unstable basic gesture repetition, high cost contributed by replacing deletion and substitution of local error by insertion operation, duration variation due the absence of timing guideline of body part motions, and limited training dataset to capture possible basic gesture variations.","PeriodicalId":145771,"journal":{"name":"2014 IEEE 3rd Global Conference on Consumer Electronics (GCCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115438183","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 present study investigated response of electroencephalogram to acute aerobic exercise with low intensity after performing mental tasks and compared with that to sustained rest for the same duration. The mean amplitude of the alpha wave in the low frequency band (8-10 Hz, low-alpha wave) showed significant decrease between the mental arithmetic and the resting state prior to the mental tasks over the entre scalp with a focus on the occipital lobe, while that of the alpha wave in the high frequency band (10-13 Hz, high-alpha wave) did not show such reduction. The weighted mean frequency with amplitude of the alpha wave (8-13 Hz) was increased at the occipital lobe during the mental tasks due to the increase of the weighted mean frequency of the low-alpha wave. The amplitudes of the alpha, low-alpha and high-alpha waves were beginning to be increased after the onset of an acute exercise; significant difference in the high-alpha wave was seen between the entire duration of the exercise and the resting state prior to the tasks. Moreover, the weighted mean frequency of the high-alpha wave showed the increase during the most of the duration of exercise, whereas that of the low-alpha wave almost stayed during the exercise. Such modulation in amplitude and frequency was immediately deteriorated after the end of the exercise and became comparable to the modulation by the sustained rest in 10 minutes after the exercise. The observation obtained suggests that the mental calculation mainly reduced the amplitude and increased the frequency of the low-alpha wave, while the aerobic exercise increased the amplitude and frequency of the high-alpha wave. Increase of the high-alpha wave during the exercise may reflect an activation of serotonergic system.","PeriodicalId":145771,"journal":{"name":"2014 IEEE 3rd Global Conference on Consumer Electronics (GCCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125618932","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}
