high speed wiki:
htSpeed is an Internet video conference software that uses a proprietary artificial intelligence algorithm to remove unimportant information from images. It claims to be able to transmit 30 frame/s live video over a typical ADSL connection with little time lag.Using a unique codec based on pixelwise compression, instead of mpeg-type, frame-based compression, SightSpeed essentially only transfers the pixels that experience a change of state on screen. If the background does not change much, it will not be updated very frequently, except for where change does occur.

shape wiki:
>For other uses, see Shape (disambiguation). In geometry, two objects are of the same shape if one can be transformed to another (ignoring color) by dilating (that is, by multiplying all distances by the same factor) and then, if necessary, rotating and translating. Dilation changes the size but not the shape; rotation and translation preserve both size and shape.
