20100318300 | Method for Object Recognition - A method for recognizing an object that has a plurality of expressions of abstract object characteristics, and is associated with an object characteristic class of a hierarchical system of object characteristic classes stored in a first memory. The method includes i) observing at least one location at which the object is presumed to be present, using a plurality of sensors in a sensor population, each of said sensors responding to at least one object characteristic and accordingly emitting a sensor signal; ii) checking whether each of the emitted sensor signals exceeds a specified threshold value for the sensor signals, and accepting sensor signals which exceed the threshold value; iii) pairing combinations of the sensor characteristics, for the accepted sensor signals obtained in ii) to form identification characteristic pairs; iv) comparing the population of identification characteristic pairs obtained in iii) to the object characteristic classes stored in the first memory; and v) identifying the object, based on the object characteristic class, whose object characteristic pairs are identical to the identification characteristic pairs obtained in iii). | 12-16-2010 |

20110311106 | Method for The Identification of Objects - A method for the identification of objects in a predetermined target area involves recording a first and a second height profile of the target area, wherein the two height profiles are recorded at a predeterminable time interval. A height difference profile is determined from the first and the second height profile. The height difference profile is subdivided in equidistant horizontal height sections. The positions of the centroids of the surface areas enclosed by the respective contour lines of the horizontal height sections are calculated and the determined height difference profile and the calculated centroids of the surface areas are supplied to a system for classifying objects. | 12-22-2011 |
20120033877 | Method for Entropy-Based Determination of Object Edge Curves - In a method for determining object edge curves in a recorded image of a multispectral camera, the image recorded is converted into a false color image, hue value from the HSV color space is assigned to each pixel in the false color image such that the hue value corresponds to a hue angle on a predetermined color circle, and the pixels are classified as object pixels and background pixels, such that those pixels with hue values that are within a predetermined value range are defined as the object pixels. An entropy profile is then determined by way of a displaceable evaluation window, such that the entropy of mixing S is calculated for each pixel from the object pixels and background pixels according to the equation: | 02-09-2012 |
