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.

仿照着《小波去噪中软硬阈值的一种改良折衷法》一文写的程序，对比了软、硬以及软硬阈值折衷法的信噪比及均方根误差。仿真出来之后，原信号的信噪比是负的，不知道为什么？均方根误差的值也比较大，不知何解？信噪比和均方根误差是参照《基于matlab的小波去噪仿真》：吴伟，《信息与电子工程》 一文写的(Modeled on the written procedures of the hard and soft threshold wavelet de-noising an improved compromise " , compared to the soft and hard compromise between the hard and soft threshold signal-to-noise ratio and root mean square error. Out of the simulation, the signal-to-noise ratio of the original signal is negative, do not know why? The value of the root mean square error is relatively large, do not know why? Signal-to-noise ratio and root mean square error with reference to the wavelet denoising matlab-based simulation: Wu Wei, " Information and Electronic Engineering" written)
