灰色系统改进累加预测 通过改变矩阵x实现不同原序列的灰色系统预测,nn表示预测个数(Gray predicted cumulative improvement achieved by changing the matrix of x different of the original sequence by Grey System Theory, nn predict that the number of)

Circles We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of fixed radius can be described fully by the location of its center (x, y). Think of each feature (edge) point on the circle as saying, ”if I’m on the circle, the center must be in one of these places”. It turns out that the locus of these votes is itself a circle. But what about circles of unknown size? In this case, we need a third parameter: the radius of the circle. So, we can parameterize circles of arbitrary size by (x, y, r). Instead of casting votes in a circular pattern into a two-dimensional accumulator, we cast votes in circles of successively larger size in a three-dimensional accumulator.

说明：  扩展卡尔曼滤波算法是目前最常用的非线性滤波算法之一，其核心思想就是将非线性模型线性化后，然后采用标准的卡尔曼滤波算法进行迭代滤波，这是一种最基本的解决非线性滤波问题的方法，目前在目标跟踪领域得到了广泛的运用。(Extended Kalman filter is the most commonly used one of nonlinear filtering algorithm, the core idea is that the nonlinear model is linearized, and then apply the standard Kalman filtering algorithm to filter, which is one of the most solve the basic problem of nonlinear filtering methods, the current target tracking has been widely used.)
