基于卷积神经网络的人脸表情识别

Facial Expressions Recognition with Convolutional Neural Networks

Subodh Lonkar

摘要:

几个世纪以来,人类已经发展并获得了许多沟通方式。但几乎没有一个能像面部表情那样自然和本能。另一方面,神经网络已经席卷全球。毫不奇怪,计算机视觉领域和面部表情识别问题并没有保持不变。虽然广泛的技术已被应用,实现极高的精度和准备高度鲁棒的FER系统仍然是一个挑战,由于在人脸的异质细节。在本文中,我们将深入研究如何利用神经网络(更具体地说,卷积神经网络(CNN))来实现面部表情识别系统(FER)。我们采用深度学习和计算机视觉的基本概念,采用各种架构,微调其超参数并使用各种优化方法进行实验,并在不使用任何额外训练数据的情况下,在FER2013数据集上展示了70.10%的最先进的单网络准确度。

英文摘要:

Over the centuries, humans have developed and acquired a number of ways to communicate. But hardly any of them can be as natural and instinctive as facial expressions. On the other hand, neural networks have taken the world by storm. And no surprises, that the area of Computer Vision and the problem of facial expressions recognitions hasn't remained untouched. Although a wide range of techniques have been applied, achieving extremely high accuracies and preparing highly robust FER systems still remains a challenge due to heterogeneous details in human faces. In this paper, we will be deep diving into implementing a system for recognition of facial expressions (FER) by leveraging neural networks, and more specifically, Convolutional Neural Networks (CNNs). We adopt the fundamental concepts of deep learning and computer vision with various architectures, fine-tune it's hyperparameters and experiment with various optimization methods and demonstrate a state-of-the-art single-network-accuracy of 70.10% on the FER2013 dataset without using any additional training data.
