Recognizing human gender plays an important role in many human computer interaction (HCI) areas. For example, search engines need an image filter to determine the gender of people in images from the Internet; demographic research can use gender information extracted from images to count the number of men and women entering a shopping mall or movie theater; a “smart building”might use gender for surveillance and control of access to certain areas. Besides these kinds of broad applications, gender recognition itself is an important research topic in both psychology and computer vision.

In psychology studies for HCI, the main focus is about how humans discriminate between males and females and what kind of features are more discriminative. A successful gender classification approach can boost the performance of many other applications including face recognition and smart human-computer interfaces. Despite its importance, it has received relatively little attention in the literature.

We have developed a system for facial gender recognition that is capable to extract from image most informative features using an approach based on genetic algorithms.

The code has been tested with Stanford Medical Student Face Database achieving an excellent recognition rate of 93.60% (200 female images and 200 male images, 90% used for training and 10% used for testing, hence there are 360 training images and 40 test images in total randomly selected and no overlap exists between the training and test images).

Human face contains a variety of information for adaptive social interactions amongst people. In fact, individuals are able to process a face in a variety of ways to categorize it by its identity, along with a number of other demographic characteristics, such as gender, ethnicity, and age. In particular, recognizing human gender is important since people respond differently according to gender. In addition, a successful gender classification approach can boost the performance of many other applications, including person recognition and smart human-computer interfaces.

We have developed an algorithm for gender recognition based on AdaBoost algorithm. Boosting has been proposed to improve the accuracy of any given learning algorithm. In Boosting one generally creates a classifier with accuracy on the training set greater than an average performance, and then adds new component classifiers to form an ensemble whose joint decision rule has arbitrarily high accuracy on the training set. In such a case, we say that the classification performance has been “boosted”. In overview, the technique train successive component classifiers with a subset of the entire training data that is “most informative” given the current set of component classifiers. AdaBoost (Adaptive Boosting) is a typical instance of Boosting learning. In AdaBoost, each training pattern is assigned a weight that determines its probability of being selected for some individual component classifier. Generally, one initializes the weights across the training set to be uniform. In the learning process, if a training pattern has been accurately classified, then its chance of being used again in a subsequent component classifier is decreased; conversely, if the pattern is not accurately classified, then its chance of being used again is increased.

The code has been tested with Stanford Medical Student Face Database achieving an excellent recognition rate of 89.61% (200 female images and 200 male images, 90% used for training and 10% used for testing, hence there are 360 training images and 40 test images in total randomly selected and no overlap exists between the training and test images).
