Device Enables Computer to Identify Whether User is Male or Female

April 7, 2011 - PRLog -- A report from Science Daily, published yesterday, says that Researchers from the Computational Intelligence Group at the University in Madrid, have developed a system that analysis a video signal in real time and calculates the gender of the faces pictured in the images.This way, a computer can determine whether the faces pictured in the images or videos belong to a man or a woman.

Devices can be built to measure television or advertising video audiences by gathering demographic information about spectators. The new device is also useful for conducting market research at shopping centers, stores, banks or any other business using cameras to count people and extract demographic information. Another application is interactive kiosks with a virtual vendor, as the device automatically extracts information about the user, such as the person's gender, to improve interaction.

The developed technique is applicable in devices that have low computational resources, like telephones or intelligent cameras. The invention is a device equipped with a camera that captures digital images and is connected to an image processing system.The image processing system trims each face detection image to the size of 25x25 pixels. An elliptical mask, designed to eliminate background interference, is then applied to the image, and it is equalized and classified.

One of the major research areas in informatics is the development of machines that interact with users in the same way as human beings communicate with each other. This research is a step further in this direction.
