`video699.quadrangle.deque`¶

This module implements a moving convex quadrangle using the deque data structure.

Module Contents¶

class video699.quadrangle.deque.DequeMovingConvexQuadrangle(current_quadrangle, window_size=None)¶

A convex quadrangle that moves in time represented by a deque.

Parameters:	current_quadrangle (ConvexQuadrangleABC) – The latest coordinates of the moving convex quadrangle. window_size (int or None, optional) – The maximum number of previous time frames for which the quadrangle movements are stored. If `None` or unspecified, then the number of time frames is unbounded.

current_quadrangle¶: ConvexQuadrangleABC – The latest coordinates of the moving convex quadrangle.

Raises:	`ValueError` – If the window size is less than two.
