Preface

ICISP 2010, the International Conference on Image and Signal Processing, was

the fourth ICISP conference, and was held in Trois-Rivi`eres, Qu´ebec, Canada.

Historically, ICISP is a conference resulting from the actions of researchers of

Canada, France and Morocco. Previous editions of ICISP were held in Cherbourg￾Octeville (France), Agadir (Morocco), and Agadir (Morocco) in 2008, 2003 and

2001, respectively. ICISP 2010 was sponsored by EURASIP (European Associa￾tion for Image and Signal Processing) and IAPR (International Association for

Pattern Recognition).

The response to the call for papers for ICISP 2010 was encouraging. From

165 full papers submitted, 69 were finally accepted (54 oral presentations, and

15 posters). The review process was carried out by the Program Committee

members; all are experts in various image and signal processing areas. Each

paper was reviewed by atleast two reviewers, and also checked by the conference

Co-chairs. The quality of the papers in these proceedings is attributed first to

the authors, and second to the quality of the reviews provided by the experts.

We would like to thank the authors for responding to our call, and we thank the

reviewers for their excellent work.

We were very pleased to be able to include in the conference program keynote

talks by three world-renowned experts: Yann Lecun, Silver Professor of Com￾puter Science and Neural Science, The Courant Institute of Mathematical Sci￾ences and Center for Neural Science, New York University (USA); Theo Gevers,

Associate Professor, Faculty of Science, University of Amsterdam (The Nether￾lands); and Leo Grady, Senior Member of Technical Staff with Siemens Corporate

Research in Princeton, New Jersey (USA).

We would like to thank the members of the Local Organizing Committee for

their advice and help. We would also like to thank Olivier Lezoray for preparing

the proceedings and the remote sites of the Universit´e de Caen Basse-Normandie

located in the Manche for their support. We are grateful to Springer’s editorial

staff for supporting this publication in the LNCS series.

Finally, we were very pleased to welcome all the participants to this confer￾ence. For those who did not attend, we hope this publication provides a good

view into the research presented at the conference, and we look forward to meet￾ing you at the next ICISP conference.

Abstract. Face hallucination produces high-resolution facial images

from low-resolution inputs. In this paper, we propose a facial-parts-based

face hallucination method. Since our goal is face recognition rather than

face reconstruction, the contour information of facial-parts(such as eyes)

is important. This method reconstructs facial parts as entities instead of

dividing them into small blocks. We obtain the contours of facial parts

by using the Active Appearance Model(AAM), and transform training

images based on contours. We confirm that the proposed method signif￾icantly enhances face recognition performance.

Keywords: face hallucination, contour of facial-parts, Active Appear￾ance Model.

1 Introduction

Surveillance cameras are becoming more and more common in places such as

banks, stores, and parking lots. In most cases, however, the face sizes are very

small because the cameras are configured to capture very wide views. The low

resolution of these face images is a primary obstacle to effective face identification

and recognition. To gain the detailed facial features needed for recognition, it

is necessary to process the low-resolution image captured so as to generate a

high-resolution face image. This technique, called face hallucination, was first

proposed by Baker and Kanade[1].

A number of learning-based image hallucination techniques that generate a

high-resolution image from one low-resolution image have been proposed re￾cently. They employ a training database consisting of pairs of high- and low￾resolution image samples to output hallucinated high-resolution faces. These

methods are based on either global models or the patch approach. Wang and

Tang[2] developed an efficient scheme based on a global-model-based face hal￾lucination method. They use PCA to express the input face image as a linear

combination of low-resolution training face images, and the final high-resolution

image is synthesized by replacing the low-resolution training face images with

their high-resolution counterparts; the same combination weights are used. Un￾fortunately, their technique ignores local details to focus on global information,

so the resulting images are unclear and lack detailed features.
