Hi,

Here is the flight of a drone through the forest...

What is "temporal disparity"?

In the context of stereoscopic vision or image matching, disparity
(typically spatial) measures the difference in position of a single
point across two images (e.g., left and right).

When applied to the temporal domain, temporal disparity therefore
refers to:
- The positional difference of a point or feature between two
consecutive images in a video sequence, reflecting motion or
temporal change.
- A metric used in computer vision to estimate optical-flow or
3D structure from image sequences.

Measuring optical-flow between successive images matched over time
— by estimating projective dominant motion — reveals "tem
poral
disparity".

Best regards,
