What is the meaning of smoothing in image processing?

Image smoothing is a digital image processing technique that reduces and suppresses image noises. In the spatial domain, neighborhood averaging can generally be used to achieve the purpose of smoothing. Commonly seen smoothing filters include average smoothing, Gaussian smoothing, and adaptive smoothing.

What do you mean by optical flow?

Optical flow is a technique used to describe image motion. It is usually applied to a series of images that have a small time step between them, for example, video frames. Optical flow calculates a velocity for points within the images, and provides an estimation of where points could be in the next image sequence.

What is optical flow on a drone?

“Optic flow is the apparent motion of objects caused by your own motion; as you descend to the ground a downward-pointing camera will see objects on the ground looming larger as it approaches them,” he explained.

Which optical flow method is most accurate?

At present, supervised methods are the most successful category of deep learning methods for optical flow with respect to accuracy and efficiency.
