Abstract
A method and system for compression encoding a video signal representative of a plurality of image frames which include a starting frame, an ending frame, and at least one intermediate frame, provides for identifying key points of at least one object in the starting and ending frames. For each object, a mathematical transformation is determined which estimates a representation of the corresponding key points in each intermediate frame by mapping the feature points from the starting frame to the ending frame. The representation of the object in the starting frame and the mathematical transformation are encoded and multiplexed to form an object bit stream. Each object bit stream produced in response to a set of image frames is then multiplexed to form an image bit stream. A signal-to-noise ratio can be scaled by adjusting the number of feature points identified, which in turn allows the compression ratio to be selectively changed.
