Denote a particular R-table for a shape S by R(ɸ). Simple transformations to this table will allow it to detect scaled or rotated instances of the same shape. For example, if the shape is scaled by s and this transformation is denoted by T s. then T s [R(ɸ)] = sR(ɸ) i.e., all the vectors are scaled by s.
For more complicated shapes in the plane (i.e., shapes that cannot be represented analytically in some 2D space), the Generalised Hough transform [13] is used, which allows a feature to vote for a particular position, orientation and/or scaling of the shape using a predefined look-up table.The Hough transform accumulates contributions from all ...
A typical example of RDD-centric functional programming is the following Scala program that computes the frequencies of all words occurring in a set of text files and prints the most common ones. Each map , flatMap (a variant of map ) and reduceByKey takes an anonymous function that performs a simple operation on a single data item (or a pair ...
A convenient property of CSG shapes is that it is easy to classify arbitrary points as being either inside or outside the shape created by CSG. The point is simply classified against all the underlying primitives and the resulting boolean expression is evaluated. [6] This is a desirable quality for some applications such as ray tracing. [6]
