Method and apparatus for generating music file, and electronic device and storage medium

An electronic device, comprising a processor, a memory and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, performs:

• obtaining a first image;
• performing feature extraction on the first image to obtain a salient feature of the first image;
• mapping the salient feature into a musical instrument digital interface (MIDI) information coordinate system based on a position of the salient feature in the first image, so as to determine MIDI information corresponding to the salient feature;
• the MIDI information coordinate system being used for indicating correspondence between the MIDI information and time;
• and
• generating a music file based on the correspondence between the MIDI information and time;
• generating a second image corresponding to the music file;
• wherein generating a second image corresponding to the music comprises:
• receiving a second input, wherein the second input is an input for selecting a preset video template;
• determining an object video template in response to the second input;
• and
• generating the second image according to the object video template and a salient object texture map.

A readable non-transitory storage medium, wherein a program or instruction is stored on the readable storage medium, and the program or instruction, when executed by a processor, performs:

• obtaining a first image;
• performing feature extraction on the first image to obtain a salient feature of the first image;
• mapping the salient feature into a musical instrument digital interface (MIDI) information coordinate system based on a position of the salient feature in the first image, so as to determine MIDI information corresponding to the salient feature;
• the MIDI information coordinate system being used for indicating correspondence between the MIDI information and time;
• and
• generating a music file based on the correspondence between the MIDI information and time;
• generating a second image corresponding to the music file;
• wherein generating a second image corresponding to the music comprises:
• receiving a second input, wherein the second input is an input for selecting a preset video template;
• determining an object video template in response to the second input;
• and
• generating the second image according to the object video template and a salient object texture map.
