4(a)) consists of images with overlapping ellipse-shape objects that are uniformly randomly scaled, rotated, and translated. Three subsets of images were generated to represent different degrees of overlap between objects. The dataset consists of 150 sample images divided into three classes of ...
There is nothing particularly interesting in the Plane and Ray primitives, except maybe the Intersects() function, otherwise these classes are much like any other structs/classes typically found to represent a ray and plane. The Code (2): How the Classes are Used in the Demo Application Befor...
b) We put emphasis on the object classes in building twins that represent electrical elements (light switch, light, speaker, socket, elevator button), safety elements (emergency switch, smoke alarm, fire extinguisher, escape sign), plumbing system elements (pipe), and other objects with useful ...
A relate matrix that would therefore represent our first example of two lines that intersect on a line would be: ' 1*1***1** ' -- Identify road segments that cross on a line SELECT a.id FROM roads a, roads b WHERE a.id != b.id AND a.geom && b.geom AND ST_Relate(a.geom...
That is, we have found the correspondence between the 2D and 3D 5-tuples. A different view of the 5-tuple will give rise to a different line in 3D, but still passing through the same point. To recognize objects we thus look for instances in which lines obtained from the image pass ...
With the path object, we can represent any 2d shape we want. Another constraint that we have on the cross-sections is that we only support cross-sections without any holes. In conclusion, we support any cross-section that can be defined as a sequence of vertices in 2D space. 4.5 ...
lines320and331,333,335, and337represent corresponding region paths and form the regions or partitions of converted PMP300b.Since each planar map partition is by definition a simply connected region, a mean value coordinates evaluation or the like can be performed as usual. The conversion of a ...
lines are drawn on the scale points on the ground measuring line to the CV in the preset embodiment of FIG. 1 and to measuring points MP in FIG. 2. At the point where these lines cross the picture ground line, they represent the scaled points on the picture ground line that are scaled...
The sectors I, III and V respectively represent the roll-off areas at the label box, the gripper cylinder and the adhesive application roller. The sectors II, IV and VI respectively represent the intervening intermediate areas. The diagram shows that in all the regions, the angular velocity ...
