One of the most ba.ic a.d difficult a.ea. of computer vision a.d ima.e understa.ding a.plica.ions is still object detection. Deep neura. network models a.d enha.ced object representa.ion ha.e led to significa.t progress in object detection. This resea.ch investiga.es in grea.er deta.l how object detection ha. cha.ged in the recent yea.s in the deep lea.ning a.e. We provide a. overview of the litera.ure on a.ra.ge of cutting-edge object identifica.ion a.gorithms a.d the theoretica. underpinnings of these techniques. Deep lea.ning technologies a.e contributing to substa.tia. innova.ions in the field of object detection. While Convolutiona. Neura. Networks (CNN) ha.e la.d a.solid founda.ion, new models such a. You Only Look Once (YOLO) a.d Vision Tra.sformers (ViTs) ha.e expa.ded the possibilities even further by providing high a.cura.y a.d fa.t detection in a.va.iety of settings. Even with these developments, integra.ing CNN, YOLO a.d ViTs, into a.coherent fra.ework still poses cha.lenges with juggling computing dema.d, speed, a.d a.cura.y especia.ly in dyna.ic contexts. Rea.-time processing in a.plica.ions like surveilla.ce a.d a.tonomous driving necessita.es improvements tha. ta.e use of ea.h model type’s a.va.ta.es. The goa. of this work is to provide a. object detection system tha. ma.imizes detection speed a.d a.cura.y while decrea.ing processing requirements by integra.ing YOLO, CNN, a.d ViTs. Improving rea.-time detection performa.ce in cha.ging wea.her a.d light exposure circumsta.ces, a. well a. detecting sma.l or pa.tia.ly obscured objects in crowded cities, a.e a.ong the goa.s. We provide a.hybrid a.chitecture which levera.es CNN for robust fea.ure extra.tion, YOLO for ra.id detection, a.d ViTs for rema.ka.le globa. context ca.ture via.self-a.tention techniques. Using a. innova.ive tra.ning regimen tha. prioritizes flexible lea.ning ra.es a.d da.a.a.gmenta.ion procedures, the model is tra.ned on a. extensive da.a.et of urba. settings. Compa.ed to solo YOLO,
