    摘要： A method of determining a partition into distinct regions of a set of coefficients representative of at least a part of an image in order to insert a watermark comprises the following steps: generation (E501) of a centred pseudo-random sequence (w) equal in size to the cardinal number (N) of the said set of coefficients, formed from centred pseudo-random sub-sequences; modulation (E502) of the said set of coefficients by the said centred pseudo-random sequence (w) in order to insert the same information bit on the said set of coefficients; and checking (E504–E508), over each region, of a criterion of detectability of the information bit inserted by modulation. Use especially for determining an adaptative partition as a function of a criterion of detectability of an information bit inserted on each region.

    摘要： A method for the prior monitoring of the detectability of a watermarking signal inserted by modulation in a set of coefficients representing for example a digital image. The method comprises the step of simulating a distortion on the set of modulated coefficients, the distortion corresponding to a given compression level of the set of coefficients before modulation, determined by optimisation of a ratio of transmission rate to distortion. The method further comprises the step of calculating a detectability test on the set of modulated coefficients after distortion, and a step of comparing the detectability test with a threshold detection value. The method is used notably for inserting a watermarking signal during the compression of a digital image.

    摘要： A retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a deployable, adjustable frame that supports the sheath and that, together with the sheath, retracts the incision. The retraction device may include an outer ring and an inner ring coupled to opposing ends of the sheath and further include means to place the sheath in tension between the inner and outer rings, thereby retracting the incision.

    摘要： The invention is a method for determining a segmentation into distinct regions of a set of coefficients representing at least part of an image in order to insert or extract a set of watermarking signals with a predetermined cardinal. The method of the invention generates a set of acceptable segmentations, calculates, for each acceptable segmentation, a probability of error on the detection of the watermarking signals inserted in said each acceptable segmentation, and selects at least a segmentation in the set of acceptable segmentations, on consideration of the probability of error subject to a constraint on the number of regions of the selected segmentation, with respect to said predetermined cardinal.
