Embodiment 2

[0091] A facial expression recognition system based on file transfer, including a client and a server;

[0092] The client includes a main loop program module and an instruction processing module; the function of the main loop module is to wait for the client to input an instruction and send it to the instruction processing module for processing, and to display it to the client after the server sends back a relevant response; the function of the instruction processing module is to analyze the instruction and Processing instructions. like image 3 As shown, when the client is working, it keeps detecting blockages in a loop, waiting for user commands. Once a user command is detected, it immediately reads the command from stdin, and interacts with the server side according to the command in stdin.

[0093] The common module between the client and the server is the file transfer module, which is a module for sending and receiving files between the client and the server, and reali...

Abstract

The invention discloses a method and system for recognizing facial expressions based on file transmission, including acquiring facial expression images uploaded by users; system preprocessing the facial expression images; The network and the trained model perform facial expression recognition and feature matching on the preprocessed facial expression image; the recognition result is output in the form of a text file, and fed back to the user through file transmission. The invention applies a file transmission module, which is convenient for users to use; it adopts a deep convolutional neural network to extract and classify facial expression image features, can quickly and accurately recognize facial expressions, and is easy to operate, stable and reliable.

Description

technical field [0001] The invention relates to the technical fields of image processing and machine learning, in particular to a method and system for recognizing facial expressions based on file transmission. Background technique [0002] Facial expression recognition technology refers to extracting facial expression features from a given facial expression image and assigning them to a specific type of facial expression. Common facial expression categories include happy, neutral, angry, disgusted, sad, and disgusted. The research on facial expression recognition has a wide range of application values. Fast facial expression recognition helps to analyze the emotions of the recognized objects, and can realize emotional communication between machines and humans in the field of intelligent machines. Facial expression recognition can also be applied to the field of Internet interest capture. Facial expression recognition is a prerequisite for computers to understand human emot...
