在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

The output characteristics of a photovoltaic (PV) array are highly non-linear. Therefore, an accurate andefficient PV model is required to study and analyze the operation of PV system in the changing environ-mental conditions. This paper proposes a precise PV simulator based on the seven-parameter electriccircuit model. The proposed simulator can generate the output characteristics of a PV system preciselyat different operating conditions. It has also enough flexibility to simulate different configurations ofPV panels with series/parallel connections. The robustness of the proposed simulator is demonstratedunder the partial shaded conditions. Additionally, the performance of the developed simulator is verifiedby interfacing it with the actual power electronic converter and maximum power point tracking (MPPT)controller. The proposed PV simulator will facilitate the design aspects of PV systems and help in behaviorassessment of newly developed controllers prior to practical implementation.
