人脸自发表情识别毕业论文

本科毕业设计做人脸情绪识别难度大。

一般来说还是挺大的，得看你想做到什么程度了，有这个想法挺好，看个人情况做吧。情绪识别原本是指个体对于他人情绪的识别，现多指AI通过获取个体的生理或非生理信号对个体的情绪状态进行自动辨别，是情感计算的一个重要组成部分。

注意事项：

情绪识别研究的内容包括面部表情、语音、心率、行为、文本和生理信号识别等方面，通过以上内容来判断用户的情绪状态。

情绪是综合了人的感觉、思想和行为的一种状态，在人与人的交流中发挥着重要作用。情绪是一种综合了人的感觉、思想和行为的状态，它包括人对外界或自身刺激的心理反应，包括伴随这种心理反应的生理反应。在人们的日常工作和生活中，情绪的作用无处不在。

The interaction between man and computer activities of daily life is increasingly becoming an important part of, especially in recent years, with the rapid development of computer technology to study the habits of the new line interpersonal communication interpersonal interaction techniques become very active at the same time also made encouraging progress, these studies include face recognition, facial expression recognition, gesture recognition, etc.. Gesture is a natural, intuitive, easy to learn human-computer interaction means. Manual directly as computer input devices, human-computer communication between the middle of the media will no longer need, the user can simply define an appropriate gesture to the surrounding machine control, therefore, gesture recognition is a human and robot interaction an important tool, but also human-computer interaction, virtual reality, an important component. However, the gesture itself, the diversity, ambiguity and the staff is a complex deformation body and the visual is inherently uncertain, coupled with staff is a complex deformation of their body and visual discomfort qualitative, making vision-based gesture recognition is a very challenging interdisciplinary research topic. This article focuses on the general context of gesture segmentation and the use of BP neural network to recognize the gesture. Gestures are defined in advance, and the input to the neural network was trained, and then collected through the use of color image opencv extract-based skin color, the color images from complex background, hand in the image, further processing and enter the neural network identification.
