Patent ID: 8682067

Claim:
A method for determining object edge curves in a recorded image of a multispectral camera comprising: converting the image recorded into a false color image, assigning a hue value from a HSV color space to each pixel in the false color image, such that the hue value corresponds to a hue angle on a predetermined color circle, classifying the pixels as object pixels and background pixels, such that pixels with hue values that are within a predetermined value range are defined as the object pixels, determining an entropy profile, by way of a displaceable evaluation window, such that the entropy of mixing S is calculated for each pixel in the recorded image from the object pixels and background pixels according to the equation S = - k ⁡ ( n A ⁢ ln ⁢ n A n A + n B + n B ⁢ ln ⁢ n B n A + n B ) where n A denotes the number of object pixels within the evaluation window, n B denotes the number of background pixels within the evaluation window and k is a proportionality factor, considering both differentiation and at least one extreme value of the entropy profile.
