DTW: Get time along path...

Queries the selected DTW object for the time along the minimal path given the time along the "x-direction". This command is deprecated, the new commands for querying are DTW: Get y time from x time... and DTW: Get x time from y time....

Setting

Time (s)
the time along the x-direction.

Behaviour

When the input time is in the interval [xmin, xmax], the returned time will be in the interval [ymin, ymax], where [xmin, xmax] and [ymin, ymax] are the domains of the two "objects" from which the DTW-object was constructed.For all other input times we assume that the two object are aligned.

We like to have a "continuous" interpretation of time for the quantized times in the x and y direction; we make the path piecewise linear. There are two special cases:

1. The local path is horizontal. We calculate the y-time from the line that connects the lower-left position of the leftmost horizontal time block to the upper-right position of the rightmost horizontal time block.

2. The local path is vertical. We calculate the y-time from the line that connects the lower-left position of the bottommost vertical time block to the upper-right position of the topmost horizontal time block.
