Introduction Requirements for a function on pairs of points
{"Image DocumentName": "Introduction Requirements for a function on pairs of points", "Image ImageDescription": "to be a distance measure: Distances are always nonnegative. The distance between a point and itself is 0. Distance is symmetric. Distance measures obey the triangle inequality; the distance from x to y to z is never less than the distance going from x to z directly. Thus, in Euclidean geometry, the shortest distance between two points is a straight line.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
