Creating a model, instead of just making measurements, is a common task in photogrammetry today. Methods can vary depending on the requirements, data availability, and type of scenery. The amount of user input is one major differentiating factor. The methods discussed in this paper align closely with a typical workflow for urban mapping from aerial photographs.

This paper presents the historic scenery of calculus of variations (CV), one of the central tools of theoretical physics, and its relashionship with genetic programming (GP) algorithms, a search method with would be considered a numerical solution for the method of variations.

The main objective of this work is to determine the reading performance of operators’ under different viewing angles of a desktop computer. The effects of text/background color, viewing distance and character size on the speed of reading were investigated. The text and/or the background color combination were varied, with constant luminance contrast. Performance was recorded in terms of words p...

When a surface is viewed through a partially-transmissive material, the optical contributions of the two layers in a given viewing direction are collapsed onto a single intensity in the projected image. If a computer vision system is to recover the scene correctly, it must be able to decompose or scission the image intensity into the separate contributions of the two material layers (see Fig. 1...

This paper extends previous work on the interpretation of line drawings of curved objects to include objects with tangential edges and surfaces. We present a catalogue of labelled junctions and show that the existence of a legal global labelling can be determined in linear time. However, minimising the number of invisible vertices necessary to produce a legal global labelling is shown to be NPh...

For presenting virtual objects in a real space, mixed reality (MR) technique is very effective to simulate an overview of a scenery. In interior design, for instance, the coordinates of the arrangements and the colours of the items need to be determined based on various layout plans. We propose a new framework for interactively arranging and rendering virtual objects in real space by manipulati...

This paper develops a theoretical and technological foundation for a new kind of interactive map, the augmented scene, that overlays acquired imagery of the environment on a perspective model of the surface in real time. The ground position and viewing direction of users are computed automatically, freeing them from the map orientation process. We define augmented scenes, propose some applicati...

r(lt(i), l gt t ) = { 1− ‖lt(i)−l gt t ‖2 η , if ‖lt(i)− l gt t ‖2 <= η −1, otherwise (1) where η equals the distance from the center of a viewing angle to the corner of its corresponding NFoV, i.e., √ 32.752 + 24.562 = 40.9 if we define NFOV as spanning a horizontal angle of 65.5◦ with a 4 : 3 aspect ratio. When lt == l gt t , the reward is 1, which is the maximum reward. When ‖lt(i) − l t ‖2 ...
