Publication number: 20190251695Abstract: The present invention concerns a method for assigning a pixel to one of a foreground pixel set and a background pixel set. In this method, if a first condition is met the pixel is assigned to the background pixel set, and if the first condition is not met and a second condition is met, the pixel is assigned to the foreground pixel set. The method comprises a step (S100) of calculating a probability that the pixel belongs to a foreground-relevant object according to a semantic segmentation algorithm, the first condition is that this probability that the pixel belongs to a foreground-relevant object does not exceed a first predetermined threshold, and the second condition is that a difference between this probability that the pixel belongs to a foreground-relevant object and a baseline probability for the pixel equals or exceeds a second predetermined threshold.Type: ApplicationFiled: February 5, 2019Publication date: August 15, 2019Applicant: Universite de LiegeInventors: Marc VAN DROOGENBROECK, Marc BRAHAM, Anthony CIOPPA

Patent number: 9198747Abstract: A transobturator technique was developed for treating male urinary incontinence. This approach helped to design specific instruments to pass around the ischio-pubic branches of the male pelvis from inside to outside (i.e from the suburethral space to the thigh fold). The inside-out transobturator sling technique uses specific instruments and a polypropylene mesh with two arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. The mesh passes around the ischio-pubic branch before being tied under the bulbar urethra where it brings tension and support.Type: GrantFiled: October 29, 2007Date of Patent: December 1, 2015Assignee: Universite De Liege and Centre Hospitalier Universitaire De LiegeInventor: Jean De Leval
