Description of the technology
Fast and simple editing of special video effects
Computer science, Imaging, Computer graphics
Development completed, ready for commercialization
- Motion computation in video editing involves warping or manipulations of time in order to control the chronological time of events, including delaying or slowing down some activities while advancing or speeding up others.
- The dominant method for motion computation is the iterative motion analysis proposed by Lucas& Kanade (LK), used for both parametric motion computations and object tracking. The method requires substantial computational cost.
- Our method avoids the iterative image warping used in the original method by using a single iteration.
- The multiframe alignment overcomes the high complexity or restrictive assumptions (such as small motion or large memory) drawbacks of current multiframe alignment methods
- Experimental results show improvement in both complexity and accuracy
- Implements LK with a computational cost of a single iteration without affecting the accuracy of the estimated motions. Combined with a multiframe alignment to obtain a fast and robust alignment.
- Computer vision software for the extraction and analysis of information from images
- Appropriate to online and real time applications
- Motion computation is used for applications in: medical remote examination, security visual surveillance, robotics, intelligent transportation, mixing real and virtual objects (AR/VR), moving object tracing and video analytics
