We present algorithms for the automatic delineation of lung fields in chest radiographs. We first develop a rule-based scheme that detects lung contours using a general framework...
We study in this paper the problem of polyhedron scanning which appears for example when generating code for transformed loop nests in automatic parallelization. After a review of...
Global illumination simulates all transfers of light in a scene. The results of the simulation are then used to generate photo-realistic images. Scenes with diffuse surfaces only c...
Abstract. Patch based approaches have recently shown promising results for the recognition of visual object classes. This paper investigates the role of different properties of pat...

Generally, low frequency domain may be useful to embed a watermark in an image. However, if a watermark is embedded into low frequency components, blocking effects may occur in the...
