A Characterization of the Angle Defect and the Euler Characteristic in Dimension 2
The angle defect, which is the standard way to measure the curvatures at the vertices of polyhedral surfaces, goes back at least as far as Descartes. Although the angle defect has ...

An Analytical Solution to the Perspective-n-Point Problem for Common Planar Camera and for Catadioptric Sensor
The Perspective-N-Point problem (PNP) is a notable problem in computer vision. It consists in, given N points known in an object coordinate space and their projection onto the ima...

Types as Graphs: Continuations in Type Logical Grammar
Applying the programming-language concept of continuations, we propose a new multimodal analysis of quantification in Type Logical Grammar. Our approach naturally gives rise to a n...
