Requirements for the operation of the Video clarity detector are given in the table:
| Object images | - Image isn't noisy and isn't distorted by the artifacts of the compression algorithm
- The width and height of objects in the image must not:
- be less than 1% of the frame size (at resolutions of at least 1920x1080 pixels) or 15 pixels (at lower resolutions)
- exceed 75% of the frame size
- Speed of object movement in the image must be at least one pixel per second
- To detect an object, the duration of its visibility must be at least eight frames
- Between two frames, an object must move in the direction of a distance not exceeding its size. This condition is necessary for the correct calculation of an object track
