Mpeg sequences

Here we present some image sequences in MPEG format that illustrate results of attical techniques.

Tom Tight et Dum Dum

The following MPEG examples use sequences from Tom Tight et Dum Dum. This is about the only real movie sequence that I have found that is suitable and has appropriate copyright. Please suggest other examples.

These are of the longest continuous sequence of frames in the Tom Tight set. There is one other of equal length, but of distractingly lower quality.
They are designed for 30fps NTSC, but you are likely to want to do some frame-by-frame stepping.
The strength is shown in the bottom-left corner, with the frame number in the bottom-right. The strength of the enhancement is varied with the intention of illustrating effects.
The strengths shown are not recommendations, and in some cases are obviously too strong.
Note that a feature of the video compression software is that it can take a frame or two for the output to fully catch up with sudden changes in a portion of the picture. Or, to put it another way, beware of comparing two frames too closely.

The sequences

Time sequences (3.5M). This shows an original sequence of frames, an enhanced version, and the same for the central portion of the picture.
Sequences of varying strength (6.5M). This shows the effect on one frame of changing the strength. The results with some fixed strengths are compared with the original image.
Sequences with partial images shown together (2M). This shows two time sequences together, one for the original images, the other for the results with a fixed strength.
