Title: Introduction to Face Recognition and Novel Trends.



The security field uses three different types of authentication: something you know, something you have, or something you are - a biometric. It ranges from fingerprints to retina, iris or facial characteristics. Biometrics is bound to become a part of our everyday life, playing a key role in enhancing security, residing in smart cards or passports and supporting personalized Web e-commerce services. Face recognition (FR) is one of the most attractive biometrics for a broad range of applications. As it is the way people use to recognize each other, it is one of the most easily accepted biometrics. Furthermore, it is intuitive from the user's point of view and doesn't need any contact.2-D FR has been widely studied for decades and provides relevant performances. Nevertheless, such good results can only be obtained by applying tight constraints with respect to pose, illumination and expression of the face.The major difficulty in FR is related to the existence of these three sources of variations. In this presentation, we will discuss on the possible contribution of video (i.e. dynamic features) for FR to improve performances of authentication while keeping existing advantages of face recognition from 2-D images. Combining with physiological parameters (i.e. related to the appearance) within a multimodal framework, behavioral parameters (i.e. related to head motion and facial mimics) would be helpful in the design of a person system more robust to pose, illumination and expression variations. This presentation will also include some points on very recent works on soft biometrics. It consists in extracting limited information from enrolled or even unknown persons such as gender, age, presence of eyeglasses, facial hair, color of eyes.Finally, another major issue in biometrics is the security of the system, and not only its robustness. In the specific case of face recognition, one possible attack is the replay attack, i.e. the use of an ID picture from someone else.

Title : The Past, Present, and Future of Visual Quality Assessment.



Despite great advances in digital image and video technologies and their integration in various applications, the quality of visual media is far from perfect due to many factors that can affect or impair the perceived quality of the visual media. Such factors include acquisition,processing, compression, transmission,  protection, display, printing, and reproduction.
Furthermore, recent advances in visual technologies have added new challenges to the field of visual quality assessment. This talk provides an overview of the field of visual quality assessment including past efforts, current trends, challenges, and future directions.

Title: Circular Harmonic Functions: an unifying mathematical framework  for image  restoration, enhancement, indexing, retrieval and recognition.


Ability to efficiently  co-create and share electronic media contents represents one major challenge of future internet.  To fullfill user expectations  while avoiding “Digital Divide 2.0” effects, induced by the inability to employ the new technologies, low cost,  simple to use, possibly automatic solutions for all those basic operations like image and video acquisition, restoration, enhancement, indexing and retrieval,  involved in the Networked Electronic Media chain have to be deployed in the mid term. However, computational and storage complexities  can be efficiently faced whenever we are able to employ an unified  mathematical framework for representing the  image and video  contents and fullfill the above mentioned tasks. Thus,  this contribution explores the potentialities of hypercomplete image and video representations based on Circular Harmonic Functions (CHFS).  These kinds of representations that are directly related to the Fourier’s series expansion of images when represented in a polar domain, in addition to many  relevant mathematical proporties, have the property of including in the basis set elements like edges, lines and corners, particularly relevant for the human visual system. Thus their adoption can reduce the effort paid by the user in taking control of the technlogy still assuring the optimality of  the devised solutions. In particular the subject of the talk will be the review of the mathematical properties of the Gauss-Laguerre CHFs, including the Dyadic Wavelets that can be constructed starting from them, and the main applications that have been recently realized by the author and his collaborators  in the fields of image restoration and enhancement, edge extraction, object recognition and image indexing and retrieval.   Finally a general architecture for multiview image processing and understanding based on CHFs will be discussed.

Title: Near-infrared revisited: Applications in Computational Photography and Computer Vision



Silicon-based digital camera sensors exhibit significant sensitivity beyond the visible spectrum (400-700nm). They are able to capture wavelengths up to 1100 nm, i.e., they are sensitive to near-infrared (NIR) radiation. This additional information is conventionally treated as noise and is absorbed by a NIR-blocking filter affixed to the sensor. We show that retaining instead of removing NIR information can significantly improve certain image processing and computer vision tasks. Indeed, intrinsic properties of the NIR wavelength band guarantee that images can be sharper, less affected by man-made colorants, and more resilient to changing light conditions. We illustrate the benefits of using NIR images in conjunction with standard color images in applications such as de-hazing, single and multiple illuminant detection, material classification, and skin rendering. The design of a camera than can simultaneously capture visible and NIR information on one single sensor will also be discussed.
