Introducing noise to the system can improve the accuracy by changing the level of quantization; however, this may not be easy to employ in practice. For a digital weighing scale the method may be implemented by repeating measurement and addition of a random known weight to the object being weighed every time the weight is measured. The method may be called Multi-Measurement of a single quantity Using Noise (MMUN). The theory of the method has already been proved. The current papers employ the method for a particular application in which the area of an object is being measured by a vision system experimentally. The results of experimental measurements show improvement of the accuracy beyond the resolution of the measuring device. 收起
