利用非线性结构张量处理一些图形问题，能够有效的解决和优化现成的处理方法-In this article, we introduce nonlinear versions of the popular structure tensor, also known as second moment matrix. These nonlinear structure tensors replace the Gaussian smoothing of the classical structure te

机械优化设计主要包括建立优化设计问题的数学模型和选择合适的优化方法及程序两方面的内容.基于二次插值法的基本原理,通过实例,编写MATLAB程序进行求解,计算结果说明了二次插值法是一种求解一元函数极小点问题最优解的可行高效的方法.-Mechanical optimization design includes a mathematical model to optimize the design of the problem and choose the appropriate two aspec
