Automatic Contours Generation from Stereopaired Photographs

Fast Generation of multiresolution surfaces from Contours

Surface reconstruction from contours is an important problem especially in medical applications. Other uses include reconstruction from topographic data, or isosurface generation in general. The drawback of existing reconstruction algorithms from contours is, that they are relatively complicated and often have numerical problems. Furthermore, algorithms to generate multiresolution surface model...

Automatic Segmentation of Aerial Photographs

Automatic discrimination of actinic keratoses from clinical photographs

BACKGROUND AND OBJECTIVE Actinic keratoses (AK) are common premalignant skin lesions that can progress to invasive skin squamous cell carcinoma (sSCC). The subtle accumulation of multiple AK in aging individuals increases the risk of sSCC development, and this underscores the need for efficient treatment and patient follow-up. Our objectives were to develop a method based on color texture analy...

Semi-automatic Road Extraction from Digital Aerial Photographs

By means of the progress in photogrammetry; it is now possible to produce the maps of huge areas more quickly and economically but the production steps are still expensive and time consuming. In recent years, parallel to the development in photogrammetry, more effective methods are researched to make available digitizing line features like roads full automatically or semi-automatically from dig...

Semi-automatic registration of 3D orthodontics models from photographs

In orthodontics, a common practice used to diagnose and plan the treatment is the dental cast. After digitization by a CTscan or a laser scanner, the obtained 3D surface models can feed orthodontics numerical tools for computer-aided diagnosis and treatment planning. One of the pre-processing critical steps is the 3D registration of dental arches to obtain the occlusion of these numerical model...
