Motion compensation in computing, is an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation … Se mer Motion compensation exploits the fact that, often, for many frames of a movie, the only difference between one frame and another is the result of either the camera moving or an object in the frame moving. In reference to a video … Se mer The following is a simplistic illustrated explanation of how motion compensation works. Two successive frames were captured from the movie Se mer In global motion compensation, the motion model basically reflects camera motions such as: • Dolly — moving the camera forward or backward • Track — moving the camera left or right Se mer In motion compensation, quarter or half samples are actually interpolated sub-samples caused by fractional motion vectors. Based on the … Se mer In MPEG, images are predicted from previous frames (P frames) or bidirectionally from previous and future frames (B frames). B frames are more complex because the image sequence must be transmitted and stored out of order so that the … Se mer Block motion compensation Block motion compensation (BMC), also known as motion-compensated discrete cosine transform (MC DCT), is the most widely used motion … Se mer Motion compensation is utilized in Stereoscopic Video Coding In video, time is often considered as the third dimension.

Nettet16. sep. 2024 · Dynamic positioning (DP) for station-keeping control keeps the position and heading of the vessel constant regardless of environmental disturbances from wind, waves and currents. If the point of interest on the vessel has a significant vertical offset, it will be influenced also by the roll, pitch and heave motions. Although such motions are … NettetThe heave motion to waves of a semi-submersible of simple geometry can be evaluated by treating the vessel as a collection of slender members on which the loading can be calculated using the Morison equation with deep-water linear wave theory. In this particular derivation, the clamping and wave-induced drag forces are neglected for …
