Retrieves the motion ratio of a cell on the grid.


Declaration
function MotionDetector_CellMotionRatio(x, y: LongInt): Double;


double __fastcall MotionDetector_CellMotionRatio(int x, int y)


Function MotionDetector_CellMotionRatio(x As Long, y As Long) As Double

Description

Used to retrieve the motion ratio (cell's moved pixels count / cell's total pixels count) of the cell specified by its x and y coordinates. The return value will be in the 0...1 range.
The x and y coordinates are zero-based index, from 0 to MotionDetector_GridXCount -1 and 0 to MotionDetector_GridYCount -1.
