Abstract
The invention concerns a method for digital image stabilization for removing jitter from an original sequence of images (10) generated by a camera. The original sequence (10) is applied to a stabilization algorithm (11). The global motion of a camera is estimated and filtered (110) using a default motion filter. Predetermined parameters (13, 140, 141) are extracted from both the original (10) and stabilized (12) sequences of images. A measure value is computed in order to evaluate (15) the stabilization quality and compared to a threshold. Depending on the results of the evaluation (O15, O′15) the stabilization algorithm (11) uses an alternative filter, in order to improve stabilization quality, or continues to use the default filter.
