Abstract The Niagara Escarpment is a geological feature located in southern Ontario, Canada, and the northeastern United States, comprising highly fractured sandstone, shale carbonates deposited during Ordovician Silurian periods. Differential erosion of strata has generated steep cliff face which bisects city Hamilton, Ontario. Geological fractures are widespread escarpment result formation un...

Three-dimensional (3D) building façade model reconstruction is of great significance in urban applications and real-world visualization. This paper presents a newly developed method for automatically generating 3D regular from the photogrammetric mesh model. To this end, contour tracked on irregular triangulation, then local tree based topological relationship employed to represent structure Su...

Introduction: Cuboid dislocations in isolation are rare injuries often associated with high energy mechanisms, but here we present a case of college football player low mechanism that underwent surgical treatment. Case Report: We report an 18-year-old who injured his left foot after tripping over dog and falling down the stairs. His injury was initially missed, he later found to have cuboid dis...

In this Master thesis project, we tackle the problem of 3D indoor scene understanding from a single image. Following existing approaches, we parameterize the problem as one of estimating the faces of a 3D cuboid. Towards this goal, we propose a generative model of the scene, which takes advantage of sophisticated image features while utilizing a simple prior learned from the statistics of room ...

This paper is concerned with the development o f an expert system which determines the best grasp configuration t o pick up a rectangular box. This two level system first chooses from a predetermined set of grasps, the ones best suited for the task using a set of rules. and then computes a quality index for each possible configuration. The program is written in LISP and was tested for many diff...

Engineering industry requires line drawings for manufacturing, machining and production of engineering equipments/objects. The generation of these paper-based drawings or computerized drawings is a complex and time consuming task. Conventionally, these drawings contain three two dimensional (2D) orthographic views, namely top, front and side of an object. Modern trends in engineering industry r...

Reconstruction from a single view of architectural scenes is possible thanks to the automatic identification of structural perspective elements in the view. Reliable and accurate reconstruction depends strongly on a robust estimation of vanishing points. In this paper we compare different approaches for estimation of vanishing points, and we justify our choice of Danish estimator. The intersect...
