针对传统模糊核评价方法不能区分模糊平滑区域和焦点平滑区域,模糊图不易于观察的问题,进行了研究。首先对图像块进行模糊核评价,得到其初始模糊度和模糊图。然后计算图像块梯度分布相似性系数,由梯度分布相似性系数来优化模糊图。在实... 针对传统模糊核评价方法不能区分模糊平滑区域和焦点平滑区域,模糊图不易于观察的问题,进行了研究。首先对图像块进行模糊核评价,得到其初始模糊度和模糊图。然后计算图像块梯度分布相似性系数,由梯度分布相似性系数来优化模糊图。在实验数据集上的测试表明,改进后的方法适用于失焦模糊图像和运动模糊图像,能更好的捕获部分模糊图像中的清晰区域,与许多方法相比,算法耗时少,清晰区域检测更加准确。 展开更多

With the constant development of knowledge-based economy, knowledge has become the core competitiveness of enterprise, which plays a vital role in the development of enterprise and market competition. It will be helpful for enterprise managers to improve their knowledge competitiveness, if they can judge the advantage and disadvantage of knowledge competitiveness reasonably. According to the nature and the characteristic of knowledge competitiveness of enterprise, a system of evaluation index has been designed about the knowledge competitiveness of enterprise. Taking the enterprise A as an example, it is appraised by using fuzzy comprehension evaluation based on entropy weight, and has provided a new idea for the knowledge competitiveness of enterprise. 展开更多
