Improved motion segmentation based on shadow detection / Kampel, Martin (Vienna University of Technology. Pattern Recognition and Image Processing Group) ; Hanbury, Allan (Vienna University of Technology. Pattern Recognition and Image Processing Group) ; Blauensteiner, Philipp (Vienna University of Technology. Pattern Recognition and Image Processing Group) ; Wildenauer, Horst (Vienna University of Technology. Automation and Control Institute)
In this paper, we discuss common colour models for background subtraction and problems related to their utilisation are discussed. A novel approach to represent chrominance information more suitable for robust background modelling and shadow suppression is proposed. [...]

SnakeCut : an Integrated Approach Based on Active Contour and GrabCut for Automatic Foreground Object Segmentation / Prakash, Surya (Indian Institute of Technology Madras. Department of Computer Science and Engineering) ; Abhilash, R. (Indian Institute of Technology Madras. Department of Computer Science and Engineering) ; Das, Sukhendu (Indian Institute of Technology Madras. Department of Computer Science and Engineering)
Interactive techniques for extracting the foreground object from an image have been the interest of research in computer vision for a long time. This paper addresses the problem of an efficient, semi-interactive extraction of a foreground object from an image. [...]

Intelligent CCTV for Mass Transport Security : challenges and Opportunities for Video and Face Processing / Sanderson, Conrad (NICTA (Brisbane, Austràlia)) ; Bigdeli, Abbas (NICTA (Brisbane, Austràlia)) ; Shan, Ting (University of Queensland. ITEE) ; Chen, Shaokang (University of Queensland. ITEE) ; Berglund, Erik (University of Queensland. ITEE) ; Lovell, Brian C. (University of Queensland. ITEE)
CCTV surveillance systems have long been promoted as being effective in improving public safety. However due to the amount of cameras installed, many sites have abandoned expensive human monitoring and only record video for forensic purposes. [...]

Classification of Objects and Background Using Parallel Genetic Algorithm Based Clustering / Kanungo, Priyadarshi (National Institute of Technology. Department of Electrical Engineering (Rourkela, Índia)) ; Kumar Nanda, Pradipta (National Institute of Technology. Department of Electrical Engineering (Rourkela, Índia)) ; Ghosh, Asish (Indian Statistical Institute)
In this paper, two novel strategies have been proposed to obtain segmentation of an object and background in a given scene. The first one, known as Featureless(FL) approach, deals with the histogram of the original image where Parallel Genetic Algorithm (PGA) based clustering notion is used to determine the optimal threshold from the discrete nature of the histogram distribution. [...]

Automatic Detection of Facial Midline And Its Contributions To Facial Feature Extraction / Nakao, Nozomi (Mie University (Japó). Graduate School of Engineering) ; Ohyama, Wataru (Mie University (Japó). Graduate School of Engineering) ; Wakabayashi, Tetsushi (Mie University (Japó). Graduate School of Engineering) ; Kimura, Fumitaka (Mie University (Japó). Graduate School of Engineering)
We propose a novel approach for detection of the facial midline from a frontal face image. Using midline as a guide reduces computational cost required for facial feature extraction (FFE) because the midline is capable of restricting multi-dimensional searching process into one-dimensional search. [...]

Correction for Camera Roll in a Perspectively Distorted Image : cases for 2 and 3 point perspectives / Avinash, N. (College of Engineering (Mandya,Índia)) ; Murali, S. (College of Engineering (Mandya,Índia))
We propose a method for correction of camera roll in a perspectively distorted image. Here we employ the rectification of the horizon line formed from the vanishing points in order to bring back the image rotation caused from the camera roll. [...]
