Optimization of Classroom Teaching Quality Based on Multimedia Feature Extraction Technology

Introduction

The key to educational reform and innovation lies in classroom teaching. Only by actively building students' enthusiasm can the quality of classroom teaching be effectively improved (Nie, 2020). With the rapid development of computer networks, multimedia technology has been widely used in the field of education, which has changed traditional teaching methods and enhanced students' interest in learning (Deng, 2022). The use of multimedia technology in teaching can make scientific problems dynamic, simple, and real; can constantly stimulate students' interest in learning; and can cultivate their innovative consciousness and ability (Zang, 2021). Multimedia network video teaching is a digital network teaching resource. With the development of multimedia technology, video teaching resources have become increasingly rich (Wang & Moulin, 2007). A popular area of research is how to quickly retrieve and utilize teaching video resources in order to maximize their benefits (Gu & Li, 2021).
