Abstract
Disclosed is a global motion vector estimation method, which is applicable to both static and dynamic image pickup systems by employing filter recursive integration to select blocks of high characteristic value for calculation of local motion vector, and then using the blocks to directly calculate the global motion vector, so that complication and load of calculation are significantly reduced without negatively affecting the precision of result.
