Question
Which technique is used to detect and analyze regions of an image or video frame that exhibit motion?a.Pretrained models b.Template matching c.Segmentation d.Optical flow
Solution
The technique used to detect and analyze regions of an image or video frame that exhibit motion is d. Optical flow.
Here's a step-by-step explanation:
-
Optical flow is a concept in computer vision that refers to the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer (an eye or a camera) and the scene.
-
It's used to track the movement of pixels in an image or video frame over time, which can be used to determine the speed and direction of the tracked objects.
-
This technique involves comparing the intensity of pixels in a specific region of one frame with the corresponding region in the next frame. If the intensity is different,
