I will not believe my son is disordered. What is impaired and disordered is a society where, in order to gain some level of understanding and acceptance of differences, a child has to be considered abnormal.
The Contrast Sensitivity Function
Prepared by Peter Wenderoth
Imagine that you are driving a car in a very thick fog. Objects which are normally easily seen, like black writing on a white billboard, will be hard to see because the black writing and the white background will both be greyish. That is the difference between whites and blacks - contrast - will be reduced
Abstract
The Earth Mover's Distance (EMD) between two weighted point sets (point distributions) is a distance measure commonly used in computer vision for color-based image retrieval and shape matching. It measures the minimum amount of work needed to transform one set into the other one by weight transportation. We study the following shape matching problem: Given two weighted point sets A and B in the plane, compute a rigid motion of A that minimizes its Earth Mover's Distance to B. No algorithm is known that computes an exact solution to this problem. We present simple FPTASs and polynomial-time (2+ε)-approximation algorithms for the minimum Euclidean EMD between A and B under translations and rigid motions. Earth Movers Distance
