However, individual works have focused on sophisticated methodologies with particular sport types and there has been a lack of scalable and holistic frameworks in this field. This article proposes a solution and presents a systematic and generic approach which is experimented on a relatively large-scale sports consortia. The system aims at the event detection scenario of an input video with an orderly sequential process. Initially, domain knowledge-independent local descriptors are extracted homogeneously from the input video sequence. Then the video representation is created by adopting a bag-of-visual-words (BoW) model. The video\u2019s genre is first identified by applying the k-nearest neighbor (k-NN) classifiers on the initially obtained video representation, and various dissimilarity measures are assessed and evaluated analytically. Subsequently, an unsupervised probabilistic latent semantic analysis (PLSA)-based approach is employed at the same histogram-based video representation, characterizing each frame of video sequence into one of four view groups, namely closed-up-view, mid-view, long-view, and outer-field-view. Finally, a hidden conditional random field (HCRF) structured prediction model is utilized for interesting event detection. From experimental results, k-NN classifier using KL-divergence measurement demonstrates the best accuracy at 82.16% for genre categorization. Supervised SVM and unsupervised PLSA have average classification accuracies at 82.86% and 68.13%, respectively. The HCRF model achieves 92.31% accuracy using the unsupervised PLSA based label input, which is comparable with the supervised SVM based input at an accuracy of 93.08%. In general, such a systematic approach can be widely applied in processing massive videos generically.<\/jats:p>","DOI":"10.1145\/2168752.2168760","type":"journal-article","created":{"date-parts":[[2012,10,12]],"date-time":"2012-10-12T20:56:02Z","timestamp":1350075362000},"page":"1-29","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["A Generic Approach for Systematic Analysis of Sports Videos"],"prefix":"10.1145","volume":"3","author":[{"given":"Ning","family":"Zhang","sequence":"first","affiliation":[{"name":"Ryerson University"}]},{"given":"Ling-Yu","family":"Duan","sequence":"additional","affiliation":[{"name":"Peking University"}]},{"given":"Lingfang","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Computing Technology, Chinese Academy of Sciences"}]},{"given":"Qingming","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute of Computing Technology, Chinese Academy of Sciences"}]},{"given":"Jun","family":"Du","sequence":"additional","affiliation":[{"name":"NEC Research Labs, China"}]},{"given":"Wen","family":"Gao","sequence":"additional","affiliation":[{"name":"Peking University"}]},{"given":"Ling","family":"Guan","sequence":"additional","affiliation":[{"name":"Ryerson University"}]}],"member":"320","published-online":{"date-parts":[[2012,5]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/6046.985555"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/11744023_32"},{"volume-title":"Proceedings of the IEEE International Conference on Multimedia and Expo (ICME). 1329--1332","author":"Benmokhtar R.","key":"e_1_2_1_3_1","unstructured":"Benmokhtar , R. , Huet , B. , and Berrani , S . 2008.
