Embodiment Construction

[0032] Such as figure 1 Shown is a flow chart of a method for generating music based on complex network images of the present invention, the method includes the following steps:

[0033] Step 1: Extract the gray-scale code array corresponding to the region of interest of the gray-scale image, and multiply three consecutive adjacent gray-scale codes in the gray-scale code array to obtain a gray-scale product array;

[0034] The background color of the original image and other non-interesting areas are ignored by some rendering or comparison and judgment methods to prevent the final music from being unchanged. For example, in a face image with a white background, the white background must be omitted to ensure that the grayscale matrix is ​​not sparse. This step is essentially to extract effective information on the picture. Among them, the grayscale code array corresponding to the region of interest of the extracted grayscale image is specifically:

[0035] Step 1.1: remove t...

Abstract

The invention discloses a method for generating music by an image on the basis of a complex network. The method comprises the following steps that: 1: extracting a gray code corresponding to a regionof interest of a gray image, and multiplying three continuously adjacent gray codes in a gray code array to obtain a gray product array; S2: according to a MIDI (Musical Instrument Digital Interface)pitch range, carrying out mold processing on elements in the gray product array, and obtaining a range interval and a pitch floating number so as to generate a pitch sequence; S3: taking the pitch, the length and the strength of notes in existing music as basic attributes to code note nodes, and forming a note network by the connecting edges of the note nodes; and S4: carrying out node migration on the pitch sequence generated by the image in the note network so as to generate the music. By use of the method for generating the music by the image, the complex network and knowledge rendered by amusic theory are applied to enable the music to be finger-popping and beautiful.

Description

technical field [0001] The invention belongs to the technical field of complex networks, and relates to a method for generating music based on complex network images. Background technique [0002] Since Michael Small constructed a single-note musical network and analyzed its structural properties, music research based on complex networks has attracted more and more attention. The changeable research direction and rich research content have brought about many innovative achievements in this cross-field, and the method of automatic music generation has more ways and deeper development. By analyzing a variety of different music playlists, Buldu et al. summarized the way of searching through music style, and applied the relationship between music style and music retrieval as an information source to the music recommendation engine. Cano et al. built an artist relationship network and proposed some designs for music navigation and optimization recommendations. Xie Zhigang and o...
