Problems solved by technology

[0004] At present, music art is becoming more and more diverse, but for some people who have never been exposed to professional music theory knowledge, it is difficult to create a unique piece of music by themselves, and traditional music theory teaching is also boring for children. question
Although computer image analysis technology is becoming more and more mature, there is no processing method involving the combination of music and images in the prior art, especially the method of generating music from simple pictures

Embodiment 1

[0068] A method for generating a music melody based on multi-line feature information proposed by an embodiment of the present invention includes the following steps:

[0069] (1) Set the parameters required for converting multi-line images into music: set the unit length to 100 pixels; the corresponding beat of a unit length is 1 beat / unit length; the beat frequency rhythm is 80 beats / min; the expected total music duration is 24 seconds ; The volume range is 30 decibels - 60 decibels; the pitch range is C major; the RGB value corresponding to the piano tone is #FFFFFF.

[0070] (2) According to the parameters set in step (1), the aspect ratio is 2:1 to generate an artboard with a width of 800 pixels and a height of 400 pixels, with a black brush. The time signature is four or four. draws a multi-line image such as Figure 4 shown.

[0071] (3) Extract the eigenvalues ​​in the multi-line image.

[0072] (4) Analyze the line block information within the unit length.

Abstract

The invention discloses a method, system and device for generating a music melody through multi-line feature information, and the method comprises the steps: analyzing the width of each line with unit length in a multi-line picture, the height from a center reference line, the color and other information, converting the information into the volume, tone, timbre and other numerical values in music, and synthesizing a section of music melody according to the numerical values. Through the method, audio-visual combination can be applied to the field of children music education, interests of children in music and painting art can be stimulated, and the music feeling and imagination can be cultivated.

Description

technical field [0001] The invention relates to the fields of computer image analysis and music, and in particular to a method, system and device for generating music melody based on multi-line feature information. technical background [0002] In recent years, computer-related technologies have developed rapidly, among which, the development of computer image analysis technology is particularly prominent. With the increasing maturity of this technology, the application of image analysis has become more and more extensive, such as face recognition at security check, medical image processing, and image retrieval. [0003] Music is an art form and cultural activity whose medium is a timed, regular sound wave (a type of mechanical wave). Its basic elements include strength, tonality, duration, timbre, etc. These basic elements are combined with each other to form the commonly used "form elements" of music, such as rhythm, tune, harmony, as well as strength, speed, mode, music...
