9 p, 217.0 KB Dempster-Shafer's Basic Probability Assignment Based on Fuzzy Membership Functions / Boudraa, Abdel−Ouahab (IRENav. Ecole Navale (Brest−Armees, França)) ; Bentabet, Ayachi (Sherbrooke University. Department of Mathematics and Computers Sciences) ; Salzenstein, Fabien (ULP Strasbourg. Laboratoire Phase) ; Guillon, Laurent (IRENav. Ecole Navale (Brest−Armees, França))
In this paper, an image segmentation method based on Dempster-Shafer evidence theory is proposed. Basic probability assignment (bpa) is estimated in unsupervised way using pixels fuzzy membership degrees derived from image histogram. [...]

10 p, 133.8 KB Robustness of a Blind Image Watermark Detector Designed by Orthogonal Projection / Jin, Cong (Huazhong University of Science and Technology (Wuhan, Xina). Institute for Pattern Recognition and Artificial Intelligence) ; Peng, Jiaxiong (Huazhong University of Science and Technology (Wuhan, Xina). Institute for Pattern Recognition and Artificial Intelligence)
Blind digital watermarking, which can detect watermark without using the original image, is a key technique practical intellectual property protecting systems and concealment correspondence systems. In this paper, we discussed a blind detection method for the digital image watermark. [...]

11 p, 304.6 KB Automatic instrument localization in laparoscopic surgery / Climent, Joan (Universitat Politècnica de Catalunya) ; Marés, Pere (Universitat Politècnica de Catalunya)
This paper presents a tracking algorithm for automatic instrument localization in robotically assisted laparoscopic surgery. We present a simple and robust system that doesn't need the presence of artificial marks, or special colours to distinguish the instruments. [...]

17 p, 2.1 MB An Interactive Algorithm for Image Smoothing and Segmentation / Carneiro de Andrade, Marcos (Centro de Desenvolvimento da Tecnologia Nuclear (Belo Horizonte, Brasil))
This work introduces an interactive algorithm for image smoothing and segmentation. A non-linear partial differential equation is employed to smooth the image while preserving contours. The segmentation is a region-growing and merging process initiated around image minima (seeds), which are automatically detected, labeled and eventually merged. [...]
