摘要： Disclosed is a system for automatically locating text areas in a digital image, comprising a unit (150, 160) that converts an input digital image into a binary image, a unit (170) which locates potential text areas that are applied to the binary image, and a unit (180) which selects actual text areas highlighted by the locating unit (170). The unit (170) locating potential text areas is advantageously provided with means for applying at least one morphological filter to the binary image that results from the conversion of the digital image into a binary image. The selecting unit (180) carries out a method for dividing the intensity of gray levels applied to the image supplied by a processing unit (160) that is included in the unit (150, 160) converting the digital image into a binary image.

摘要： The invention relates to a method for the image authentication of an object, using a portable data storage unit. The inventive method comprises the following steps consisting in: during a protection phase, taking at least one image of the object; splitting the image into a first part comprising information corresponding to characteristic values of the image and a second part comprising information corresponding to transformation matrices of the image; and storing the first part on the portable unit and the second part on a data storage system. The invention further consists in: during an identification phase, reading the portable unit in order to recover (i) the first information part contained in the portable unit and (ii) the second part comprising information corresponding to said portable unit, which is stored on the storage system; and reconstructing the image from said first and second information parts.

摘要： The method involves taking an image (3) of an object and decomposing the image into two parts of information (3a, 3b). The two parts of information (3a, 3b) are stored in a portable unit (4) and a data storage system (6), respectively. The portable unit is read for recovering the two parts of information. The image is reconstructed from the two parts of information. An independent claim is also included for an installation for authenticating an object.
