Abstract:
1. A method of stabilizing an image sequence, said method comprising the following phases: estimating a first global motion vector comprising a first motion component in a first direction, said first motion component having a first amplitude representing an amount of motion in the first direction, and said first global motion vector being representative of motion with respect to a reference image of a first image consisting of a pixel matrix; comparing the first amplitude of said first motion component with a threshold compensation value assigned to the first direction; associating said first motion component with either a wanted motion or an unwanted motion based at least in part on comparing the first amplitude with the threshold compensation value, said first motion component being associated with an unwanted motion when the first amplitude is smaller than said threshold compensation value and being associated with a wanted motion when the first amplitude is greater than or equal to the threshold compensation value; and processing the first image to compensate for said first motion component when said first motion component is associated with an unwanted motion, wherein said first amplitude is expressed as a number of pixels and the phase of processing the first image to compensate for the first motion component when said first motion component is associated with an unwanted motion includes translating the first image along an axis of the first direction in a direction opposite to that of the first motion component by a number of pixels equal to the first amplitude of said first component.
