Deep Convolutional Neural Network for Age Estimation based on VGG-Face Model
This work addresses age estimation for applications like security or marketing, but it is incremental as it adapts an existing model to a related task.
The paper tackled age estimation from unconstrained face images by using a deep CNN pre-trained for face recognition on the Adience database, resulting in improved performance and overcoming overfitting.
Automatic age estimation from real-world and unconstrained face images is rapidly gaining importance. In our proposed work, a deep CNN model that was trained on a database for face recognition task is used to estimate the age information on the Adience database. This paper has three significant contributions in this field. (1) This work proves that a CNN model, which was trained for face recognition task, can be utilized for age estimation to improve performance; (2) Over fitting problem can be overcome by employing a pretrained CNN on a large database for face recognition task; (3) Not only the number of training images and the number subjects in a training database effect the performance of the age estimation model, but also the pre-training task of the employed CNN determines the performance of the model.
