In the modern era.of a.growing popula.ion, it is a.duous for huma.s to monitor every a.pect of sports, events occurring a.ound us, a.d scena.ios or conditions. This recognition of different types of sports a.d events ha. increa.ingly incorpora.ed the use of ma.hine lea.ning a.d a.tificia. intelligence. This resea.ch focuses on detecting a.d recognizing events in sequentia. photos cha.a.terized by severa. fa.tors, including the size, loca.ion, a.d position of people’s body pa.ts in those pictures, a.d the influence a.ound those people. Common a.proa.hes utilized, here a.e fea.ure descriptors such a. MSER (Ma.ima.ly Sta.le Extrema. Regions), SIFT (Sca.e-Inva.ia.t Fea.ure Tra.sform), a.d DOF (degree of freedom) between the joint points a.e a.plied to the skeleton points. Moreover, for the sa.e purposes, other fea.ures such a. BRISK (Bina.y Robust Inva.ia.t Sca.a.le Keypoints), ORB (Oriented Fa.T a.d Rota.ed BRIEF), a.d HOG (Histogra. of Oriented Gra.ients) a.e a.plied on full body or silhouettes. The integra.ion of these techniques increa.es the discrimina.ive na.ure of cha.a.teristics retrieved in the identifica.ion process of the event, hence improving the efficiency a.d relia.ility of the entire procedure. These extra.ted fea.ures a.e pa.sed to the ea.ly fusion a.d DBsca. for fea.ure fusion a.d optimiza.ion. Then deep belief, network is employed for recognition. Experimenta. results demonstra.e a.sepa.a.e experiment’s detection a.era.e recognition ra.e of 87% in the HMDB51 video da.a.a.e a.d 89% in the YouTube da.a.a.e, showing a.better perspective tha. the current methods in sports a.d event identifica.ion. © 2024 The a.thors.
