严格地导出了图像结构信息的表达式,定义了一个由结构参数组成的结构空间T,并用心理测度函数的变换函数族把图像从结构空间T映射到结构信息空间,反映人从图像结构中所接收到的结构信息。还用函数来表达人对某个结构参数刺激的特殊响应。最后指出分析图像结构后可以得出结构信息,而图像人对图像结构了解越清楚,则人所得的结构信息就越大,从而人对图像的结构语义的判断就越正确。
An expression of image structure information is derived strictly. A structure space T is defined and mapped onto structural information space IT by a transformation function set based on psychometric functions. IT denotes the structure information of a given image obtained by an observer who has understood the structures of the image. A function is used to express a special response of an observer to some structure parameter stimulation. It's also pointed out that an observer can obtain the structure information after analyzing the structure of a given image. The more an observer knows about the structure of the image, the more he obtains the structure information, and the more correct decision he can make on the semantics of the structure of the image.
