The invention concerns a device and an automatic resetting method using electronic means intended for a geometric model of a scene over a picture of the scene including fixed references, the electronic means comparing the picture with model having been adjusted in perspective by homography for superimposition of the references. According to the invention, the electronic device calculates a fine homography function Hf for resetting into three phases: a first preliminary phase of determination of an average resetting homography consisting in determining an average homography function Hm applicable to the model with average adjustment over a sample of pictures of the scene taken previously, a second, rough resetting phase consisting after application of the average homography function Hm, to the model in determining a rough homography function Hg, and a third, fine resetting phase consisting after application of the rough homography function Hg to the model in determining the fine homography function Hf.

摘要:
The method is characterized in that it implements the following steps: random drawing of p candidates from the set of key images, calculation of a cost C for each candidate, selection of the candidate minimizing the cost C, determination of a subset from among the set of key images such that the key images forming the said subset have a distance from the candidate less than a threshold T, determination of a seed from among the key images of the subset such that it minimizes the cost function C for this subset, deletion of the key images of the subset to form a new set of key images for at least one new random draw and determination of a new seed according to the previous 5 steps. The field is that of the selection of shots of interest in a video sequence.
摘要:
The invention relates to a method of selecting parts of an audiovisual document. First, the document is analyzed by at least two subdividing means in order to extract from it at least two groups of audiovisual sequences. Then, selection criteria associated with each of the two subdividing means are entered. Finally, a list of sequences responding to all the selection criteria entered previously is generated.According to a refinement, the sequences are concatenated in a chronological order in order to generate an audiovisual document representative of the audiovisual document.The invention also relates to a device for displaying the sequences selected according to the method.
