一般来说，从图像中识别目标涉及将目标像素的连接组从背景像素中分离出来，并对目标进行识别或分类。由对象覆盖的图像区域的指示使得由像素组隐含地给出的信息通过命名对象而显式。隐式信息可以包含在像素的测量值中或像素相对于彼此的位置中。前者表示辐射特性，后者具有描述物体形状或拓扑的几何性质。
In general, object recognition from images is concerned with separating a connected group of object pixels from background pixels and identifying or classifying the object. The indication of the image area covered by the object makes information which is implicitly given by the group of pixels, explicit by naming the object. The implicit information can be contained in the measurement values of the pixels or in the locations of the pixels relative to each other. While the former represent radiometric properties, the latter is of geometric nature describing the shape or topology of the object.
