Abstract
The video stabilization method can generate output data for an output frame from input data of an input frame according to a perspective transform of a transform matrix. The input data used for the perspective transform can be obtained from a buffer of a predetermined depth. The transform matrix can be altered when the input data required for the transform exceeds the depth of the buffer.
