The use of digital image analysis in architectural photogrammetry allows the automation of monotonous low-level tasks and makes the interpretation of facades much easier. Different segmentation methods for a computer assisted mapping of joint contours are discussed. Exemplary the application of the watershed transform is described and a combined watershedmethod will be presented, which is well ...

Extracting 3-dimensional structure from real-world imagery and rendering it from unrestricted viewpoints is an important problem in computer vision, and increasingly, computer graphics. Despite many years of research, a system that automatically recovers realistic 3-D models from images remains elusive; most practical systems require signi cant human input. However, unlike automatic algorithms,...

Abstract With international awareness of the need to decrease greenhouse gas emissions, Danish government set a target be fossil fuel-free by 2050. To achieve that, existing buildings will retrofitted with energy-saving technologies such as improved thermal insulation. In Denmark, larger mass building stock from around 1850 1940s is preservation worthy. The construction typically solid brick wa...
