Research on SIFT-Based Audio Processing Technology in Music Teaching

The application of multimedia technology in the teaching field has many advantages, which can provide students with music-related pictures, videos and audio files, enrich teaching resources, enhance the vividness and vividness of music works and create a good classroom atmosphere. SIFT features are robust to changes in illumination, scale, rotation, viewing angle, occlusion and noise. Based on the above characteristics, many image retrieval methods based on SIFT and its improvements and variants have been proposed and achieved good research results. Introducing digital multimedia music production technology into music solfeggio teaching can make the teaching form vivid, standardize the teaching process, diversify the teaching content, improve the teaching quality and promote students' enthusiasm and interest in learning.
