    • The invention relates to an image processing device, by means of which image recognition can be carried out in real time and which can carry out an accurate and reliable recognition of objects with little or no a-priori information. An arithmetic unit is used to determine the connection probabilities between each two contour points taking into account the separation of the points from each other. At least one classifier is further provided, which selects from sets of calculated connection probabilities, sub-sets with at least three connection probabilities for possible connections between at least three adjacent contour points, of which one is a pre-determined central contour point and, for each sub-set, picks out those contour points adjacent to the central contour point which have ta possible connection with the lowest connection probability to an adjacent contour point, so long as the connection does not connect two points adjacent to the central point and then enters the non-sorted points with connectors in a contour point list, which defines the remaining connections to the central point.
    • 本发明涉及一种图像处理设备,借助于该图像处理设备可以实时进行图像识别,并且可以以很少或不具有先验信息的方式对对象进行准确和可靠的识别。 考虑到点彼此分离,算术单元用于确定每两个轮廓点之间的连接概率。 进一步提供至少一个分类器,其从至少三个相邻轮廓点之间的可能连接中选择具有至少三个连接概率的子集,其中一个是预先确定的中心轮廓点, 对于每个子集,只要连接没有连接与中心点相邻的两个点并且然后选择与中心轮廓点相邻的那些具有可能连接的轮廓点并且具有与相邻轮廓点的最低连接概率 用轮廓点列表中的连接器输入非排序点,该列表定义到中心点的剩余连接。
