    摘要: The invention relates to a method for examining an object with respect to information that is present on the object in the form of a relief-like structure. According to the inventive method, an initial height representation of the object is provided (10) which reflects the height profile of the object. The initial height representation of the object is processed using height changes in order to bring into prominence the relief-like structure in a processed representation (12, 14). The processed representation is then evaluated (16) for example by optical character recognition methods in order to extract the information that is given by the relief-like structure. The invention makes it thus possible to automatically and reliably detect information that is applied by means of relief-like structures on an object, for example a vehicle tire.

    摘要: A device for detecting a plant against a background includes a provider for providing a plurality of different photographs of the plant leaf against the background, the photographs differing in that image points of the different photographs relating to the same location of the plant leaf are illuminated with different levels of brightness, a selector for selecting such image points, from the different photographs, whose levels of brightness are within a predetermined range, an image point of a first photograph being selected for a first location of the plant leaf, and an image point of a second, different photograph being selected for a different location of the plant leaf to obtain a representation of the plant leaf against the background, the representation being composed of and/or merged from different photographs, and a segmenter for segmenting the composite photograph to obtain a segment representation having the plant leaf without the background or the background without the plant leaf.
