ABSTRACT Now a days, applications in the field of surveillance, banking and multimedia equipment are becoming more important, but since each application related to face analysis demands different requirements on the analysis process, almost all algorithms and approaches for face analysis are application dependent and a standardization or generalization is quite difficult. For that reason and since many key problems are still not completely solved, the face analysis research community is still trying to cope with face detection and recognition challenges. Local Binary Patterns were first used in order to describe ordinary textures[1] and, since a face can be seen as a composition of micro textures depending on the local situation, it is also useful for face description. The LBP descriptor consists of a global texture and a local texture representation calculated by dividing the image into blocks and computing the texture histogram for each one. The global is used for discriminating the most non-face objects (blocks), whereas the second provides specific and detailed face information which can be used not only to select faces, but also to provide face information for recognition[2].The results will be concatenated in a general descriptor vector, that will be later used to feed an adequate classifier or discriminative scheme to decide the face likeness of the input image or the identity of the input face in case of face recognition. I. INTRODUCTION Face detection and recognition are playing a very important role in our current society, due to their use for a wide range of applications such as surveillance, banking and multimedia[3] equipment as cameras and video game consoles to name just a few. Most new digital cameras have a face detection option for focusing faces automatically. Some companies have even gone further, like a well-known brand, which has just released a new functionality not only for detecting faces but also for detecting smiles by analyzing “happiness” using facial features like mouth, eye lines or lip separation, providing a new “smile shutter” feature which will only take pictures if persons smile. In addition, most consumer electronic devices such as mobile phones, laptops, video game consoles and even televisions include a small camera enabling a wide range of image processing functionalities including face detection and recognition applications. For instance a renowned TV manufacturer has built-in a camera to some of their television series to make a new feature called Intelligent Presence Sensor possible. The users’ presence is perceived[4] by detecting faces, motion, position and even age, in the area in front of the television and after a certain time with no audience, the set turns off automatically, thus saving both energy and TV life. On the other hand, other demanding applications for face detection and recognition are in the field of automatic video data indexing to cope with the increase of digital data storage. For example, to assist in the indexing of huge television contents databases by automatically labeling all videos containing the presence of a given individual. In a similar way, face detection and recognition techniques are helpful for Web Search Engines or consumers’ picture organizing applications in order to perform automatic face image searching and tagging. For instance, Google’s Picasa digital image organizer has a built-in face recognition[5] system that can associate faces with people, so that queries can be run on pictures to return all images with a specific group of people together. Another example is iPhoto, a photo organizer distributed with iLife that uses face detection to identify faces of people in photos and face recognition to match faces that look like the same person. After four decades of research and with today’s wide range of applications and new possibilities, researchers are still trying to find the algorithm that best works in different illuminations, environments, over time and with minimum error. II. FACE DETECTION AND RECOGNITION In most cases, these research areas presume that faces in an image or video sequence have been already identified and localized. Therefore, in order to build a fully automated system a robust and efficient face detection method is required, being an essential step for having success in any face processing application. Face detection is a specific case of objectclass detection, which main task is to find the position and size of objects in an image belonging to a given class. Face detection algorithms were firstly focused in the detection of frontal human faces, but nowadays[6] they attempt to be more general trying to solve face multi-view detection: in-plane rotation and out-of-plane rotation. However, face detection is still a very difficult challenge due to the high variability in size, shape, color and texture of human faces. Generally, face detection algorithms implement face detection as a binary pattern classification task. That means, that given an input image, it is divided in blocks and each block is transformed into a feature. Features from class face and non face are used to train a certain classifier. Then given a new input image, the classifier will be able to decide if the sample is a face or not. Face detection methods can be classified in the following categories |
