An arrangement for the optical evaluation of harvested crop in a harvesting machine includes a camera located for taking images of threshed out crop elements (grain and material other than grain) being conveyed within a channel of the machine. An electronic image processing system receives the images and identifies individual objects in the images, these objects being classified into predetermined object classes by way of comparing at least one of color, contour or texture features of the individual objects and corresponding characteristics of reference objects filed in a data bank. The processing system then determines the absolute or relative numbers or areas of the individual objects assigned to the respective object classes.

Embodiments of the invention relate to a method for minimizing the influence of disturbing signals during calculation of shape elements from coordinate points. An aim of the embodiments of the invention is to exclude the coordinates which are not to be locally assigned to the desired shaped element from the calculation of the shaped element. Said aim is achieved by combining compensation methods for calculating the desired type of shaped element with recognition methods for the same type of shaped element and using the recognition methods for filtering the coordinate points that are relevant for calculating the shaped element out of all input coordinate points.

A method for determining the edge position in color images, particularly for color transitions and intensity transitions is disclosed. In accordance with the method, the edge locations found in the total image or in individual color extracts coincide as closely as possible. Further, every color value F is changed to a vector representation {overscore (OF )} proceeding from a selected point O of the color space F to determine the edge location K, and in that the transition from a color F at the left of edge K to a color F at the right of edge K is determined in order to determine the edge position along a given sampling direction by means of a method based on the vector representation {overscore (OF )}. The method according to the invention is directed for determining the edge position in color images, particularly with detection of color transitions and intensity transitions in color space F.
