Embodiment Construction

[0048] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0049] The weight-based audio attention degree calculation system provided by the present invention specifically adopts the following technical scheme, see figure 1 , the weight-based audio attention degree calculation system includes an initialization module 1, an interest sound attention degree calculation module 2, a switch module 3, an interference sound attention degree calculation module 4, and an attention degree fusion module 5.

[0050] Initialization module 1 is used to set the total number i of sound types of interest and the weight λ of each sound of interest i , if there are interfering sounds that need to be excluded, set the total number of interfering sound types j, and set the weight ω of each interfering sound j ;

[0051] Interesting sound attention degree calculation module 2, for receiving the total number i of interest sound t...

Abstract

The invention relates to the technical field for processing audio frequency signals, in particular to a weight-based system and a method for calculating audio frequency attention. The system comprises an initialization module, an interesting sound attention calculation module, a switch module, a disturbing sound attention calculation module and an attention fusion module, wherein the attention fusion module calculates the intermediate results of the modules so as to obtain the weight-based attention M of interesting sound and the weight-based attention N of disturbing sound, finally calculates to obtain the fusion attention Ma which is obtained after attention fusion and output the fusion attention. The invention has the advantages that a proper attention judgment threshold value of the audio frequency attention can be easily set under different total types of interesting sound, thereby reducing the difficulty of judging the audio frequency attention and increasing the accuracy of calculating and judging the audio frequency attention.

Description

technical field [0001] The invention relates to the technical field of audio signal processing, in particular to a weight-based audio attention degree calculation system and method. Background technique [0002] Attention is the degree of human attention to objects, while audio attention is the degree of attention to audio objects and features. Currently, existing audio attention calculation methods include top-down methods and bottom-up methods. The top-down audio attention degree calculation method is based on the fact that people have different attention degrees to specific categories of objects, such as different types of sounds such as explosions and voices in the audio, and further determine the object by classifying and discriminating the objects. Whether it is the object of concern; the bottom-up audio attention calculation method is based on human beings' attention to the characteristics of the object, such as the attention to the characteristics of energy and freq...
