  • Global movement image stabilization systems and methods
    Patent number: 11494881
    Abstract: A method of global movement image stabilization may include calculating a global motion group parameter with respect to first and second sequential frames for two or more elementary 2D motion components of a motion group. Each global motion group parameter may be applied to a motion group vector field that corresponds to the elementary 2D motion component to which the respective global motion group parameter applies to generate a global motion group vector field corresponding to each elementary 2D motion component of the motion group. The global motion group vector fields may be summed pointwise to generate a global motion deformation vector field that provides global motion from the second frame to the first frame. The global deformation vector field may be cumulated with a previous cumulative global deformation vector field that provides global movement from the first frame to one or more previous frames to generate a current cumulative global motion deformation vector field.
    Type: Grant
