In the m.dern era of a growing population, it is arduous for hum.ns to m.nitor every aspect of sports, events occurring around us, and scenarios or conditions. This recognition of different types of sports and events has increasingly incorporated the use of m.chine learning and artificial intelligence. This research focuses on detecting and recognizing events in sequential photos characterized by several factors, including the size, location, and position of people’s body parts in those pictures, and the influence around those people. Com.on approaches utilized, here are feature descriptors such as m.ER (m.xim.lly Stable Extrem.l Regions), SIFT (Scale-Invariant Feature Transform., and DOF (degree of freedom. between the joint points are applied to the skeleton points. m.reover, for the sam. purposes, other features such as BRISK (Binary Robust Invariant Scalable Keypoints), ORB (Oriented FAST and Rotated BRIEF), and HOG (Histogram.of Oriented Gradients) are applied on full body or silhouettes. The integration of these techniques increases the discrim.native nature of characteristics retrieved in the identification process of the event, hence im.roving the efficiency and reliability of the entire procedure. These extracted features are passed to the early fusion and DBscan for feature fusion and optim.zation. Then deep belief, network is em.loyed for recognition. Experim.ntal results dem.nstrate a separate experim.nt’s detection average recognition rate of 87% in the Hm.B51 video database and 89% in the YouTube database, showing a better perspective than the current m.thods in sports and event identification. © 2024 The Authors.

Wild cotton species can contribute a valuable gene pool for agronom.cally desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system.is required to achieve transform.tion based goals. The present studies aim.d at optim.zing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction m.dia were tested with varying concentrations of horm.nes in which sucrose was used as nutritional source. Different explants (hypo-cotyls, cotyledon, root) were used to check the regeneration of both local cotton plants and wild relatives using T & G m.dium. BAP m.dium. CIm.m.dium. Em.S m.dium. and cell suspension m.dium. Different stages of em.ryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transform.tion m.thods.
