1. A method for temporal registration of a first sequence of first images and a second sequence of second images, to each of the first and second images being associated a signature, said method comprising the following steps: a) comparing first parts of signatures of said first images with corresponding parts of signatures of said second images, called the first comparison step, b) temporally registering each first image of said first sequence with one of the second images according to the result of said first comparison step, c) calculating for each first image a value representative of the registration quality of said first image, d) defining, for each first image for which the value representative of the registration quality is less than a threshold, a first sub-sequence comprising said first image and images of said first sequence temporally surrounding said first image and a second sub-sequence comprising the second image with which said first image is registered and images of the second sequence temporally surrounding said second image, e) comparing, for each first sub-sequence, second parts of signatures of said first images of said first sub-sequence with corresponding parts of signatures of said second images of said second corresponding sub-sequence, called the second comparison step, said second parts of signatures being different from said first parts of signatures, and b) temporally registering each first image of said first sub-sequence with one of the second images of said second sub-sequence according to the result of said second comparison step.
