Embodiment Construction
[0134] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0135] like figure 1 As shown, the present invention includes (1) preprocessing step; (2) feature extraction step; (3) multiclass support vector machine training step; (4) identification step.
[0136] This embodiment is based on the four music emotion databases established by Cyril, Pompeu Fabra University, Spain, etc., including four emotions of happiness, sadness, excitement, and excitement. There are 100 digital music files for each emotional music in the database, and the duration of each music file is 60 seconds. Divide each type of emotional digital music file in the database into two parts according to the ratio of 9:1, one part is used as a sample training data set, and the other part is used as a data set to be identified.
[0137] 1. Preprocessing steps
[0138] After the digital music files to be recognized and the digital music files in ...

The invention relates to a recognition method of digital music emotion, belonging to the field of computer pattern recognition; the recognition method solves the problem that the existing recognition method of digital music emotion can not recognize sampling-based digital music format, the sorting technology based on a multi-class support vector machine is adopted, acoustic characteristic parameters and music theory characteristic parameters are combined, so as to carry out emotion recognition of digital music; the recognition method comprises the following steps: (1) pretreatment; (2) characteristic extraction; (3) training the multi-class support vector machine; (4) recognition. The music emotion is classified into happiness, impassion, sadness and relaxation, the emotion recognition iscarried out based on a sampling-based digital music format file, the common acoustic characteristics in the speech recognition field are not only extracted, and a series of music theory characteristics are extracted according to the theory characteristics of music; meanwhile, the sorting method based on the support vector machine is adopted, the leaning speed is rapid, the sorting precision ratiois high and the recognition efficiency is improved.
Description
technical field [0001] The invention belongs to the field of computer pattern recognition, and in particular relates to a digital music emotion recognition method. Background technique [0002] Now, people hope that computers have human intelligence, so that the communication between man and machine is as smooth as the communication between people, so that the computer can play a greater role. As an important part of human intelligence, emotional intelligence is considered to be an essential and even the most critical factor for a person to succeed. Therefore, in order for a computer to have human intelligence, it must have emotional intelligence. [0003] Music is the art of sound, and its most obvious feature is its strong emotional color. Many thoughts and feelings that cannot be accurately described in language can be expressed through music. The emotion recognition problem of digital music is to hope that computers can also identify the emotional factors carried by di...
