The application of computer multimedia technology in film and television post-production

Computer multimedia technology has brought unprecedented innovation to the film and television production industry.Multimedia technology in film and television post-production mainly focuses on two aspects of image processing and audio processing, this paper selects the skin color enhancement and voice enhancement for further research.Adaptive skin color enhancement method is proposed, IMCRA-OMLSA audio enhancement method is selected, and relevant experiments are designed to compare this paper's method with other classical skin color enhancement and voice enhancement methods respectively, and the effectiveness of this paper's method in skin color enhancement and audio enhancement is examined through the results of subjective and objective evaluation.The accuracy and F1 value of this paper's adaptive skin color detection method are 0.961 and 0.945, respectively, and the performance of skin color detection is good.The adaptive skin color detection method in this paper has the best performance with a comprehensive evaluation score of 6.81.In the objective evaluation of speech enhancement, the PESQ, STOI, WSS, and RMSE values of IMCRA-OMLSA method in this paper are 2. 03, 72.36, and 38.06, respectively, which are all optimal results.On subjective evaluation, the MOS value of IMCRA-OMLSA method is 1.88 which is the highest value.IMCRA-OMLSA method has the best performance for speech enhancement.
