1. A method for detecting organs of a human body, comprising: specifying a first class of a class network, wherein the first class is associated with a first complete organ, and wherein first objects of an object network are classified as belonging to the first class; specifying a second class of the class network, wherein the second class is associated with a second complete organ, and wherein second objects of the object network are classified as belonging to the second class based on a relation between the first complete organ and the second complete organ; specifying a process hierarchy, wherein the process hierarchy includes a first process step and a second process step; performing the first process step to detect the first complete organ using the first class, wherein the first process step is implemented on a computer of an image detection system; performing the second process step to detect the second complete organ using the second class, wherein the second process step detects the second complete organ using the detection of the first complete organ; and measuring the second complete organ.
