| Problem: Video compression algorithms have become very common these days. Videos on internet, DVDs as well as game kinematics widely use well documented techniques. However, there are very few tools available for measuring the quality of a video sequence produced by an encoder. These tools are used on encoded sequences. If there were a way to control an encoder with an algorithm evaluating the quality of a video sequence, then the encoder could generate a high quality video sequence with maximum compression. |
| Motivation: DVD, Internet, game kinematics, home video, etc. |
| Approach: The approach used aims to attach a video quality evaluation module to an encoder to enable the latter to vary the compression ratio to be used. |
| Challenges: This type of program is very rare. The main challenges involve the difficulty of evaluating the quality of a video sequence as well as performing modifications directly within a video encoder. |
| Applications: DVD, Internet, game kinematics, home video, etc. |
| Expected results: The expected result is a compressed video sequence whose quality is such that if a lower rate of compression had been used, the human eye could not detect any loss of quality in the video sequence. |
