Abstract
From first and second image data descriptive for first and second pictures captured in a first temporal distance to each other, a global motion estimator unit (110) estimates a global motion vector, which is descriptive for sign and amount of a global displacement of image portions that move with respect to a first axis both when the move at the same speed and when they move at different velocities. The global motion vector improves estimation of fast moving objects. The global motion vector estimation may rely on the evaluation of a plurality of one-dimensional profiles.
Claims15
An image processing apparatus comprising
- a global motion estimator unit (110) configured to determine, from first and second image data descriptive for a first and second picture captured in a first temporal distance to each other, a global motion vector descriptive for sign and amount of a global displacement of at least two image portions with respect to a first axis both when the image portions move at the same velocity and when they move at different velocities.
A method of operating an image processing apparatus (100), the method comprising
- determining, in a global motion estimation unit from first and second image data descriptive for a first and second image captured in a first temporal distance to each other, a global motion vector descriptive for a global displacement of all image portions that move with respect to a first axis both when the image portions move at the same speed and when they move at different velocities in relation to non-moving image portions in the first and second images.
