A new image is selected as a new keyframe.
To increase or decrease the amount of time between a keyframe and a neighboring keyframe:
Homographies are estimated for the new keyframe and each of a plurality of previous keyframes for the planar object that are spatially distributed.
In one embodiment, Previous Keyframe is available only if a keyframe exists earlier in the project.
For example, loopOut("cycle", 1) loops the segment bounded by the last keyframe and second-to-last keyframe.
A key frame, once established, is compared to a next frame (18) to determine whether the next frame should be designated another key frame.
A difference between the real second key frame (F4) and the imaginary second key frame (F4’) is compressed and coded in a differential coder (DE).
A method and system for embedding a message in compressed content comprising at least one key frame and at least one non-key frame, the method comprising embedding a message in the at least on key frame.
The first image and the position and the orientation of the object to be tracked in the first image define a key image.
The second image and the corresponding position and orientation of the object to be tracked can be stored as a key image.
Every signature contains a key image — a kind of fingerprint of the secret key.
Every signature contains a key image a kind of fingerprint of the secret key.
From this collection of key frames a current key frame (212) is displayed whose associated portion comprises a present position of the position indicator (206).
The invention relates to a method of coding an image portion of an image of a video sequence, at least one image of the video sequence being a key image.
Base on the corresponding point information, an imaginary second key frame (F4’) is generated.
A key frame extractor (204) may extract a key frame from the video data automatically based on a set of criteria.
Branches comprise a key image or key word printed on an associated line.
The branches, which are comprised of a key image or keyword, which is drawn or printed on its associated line.
The branches comprise a key image or key word drawn or printed on its
The branches comprise a key image or key word drawn or printed on its associated line
