Description: 一种自适应chirplet分解的快速算法
针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点，文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数，得到其能量分布集中于信号的调频率曲线上的结论，此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计；然后通过解线性调频技术获得其初始频率和宽度的估计，仿真结果验证了本文算法的有效性。

Description: 本程序实现hough变换。Hough变换是图像处理中从图像中识别几何形状的基本方法之一。Hough变换的基本原理在于利用点与线的对偶性，将原始图像空间的给定的曲线通过曲线表达形式变为参数空间的一个点。这样就把原始图像中给定曲线的检测问题转化为寻找参数空间中的峰值问题。也即把检测整体特性转化为检测局部特性。比如直线、椭圆、圆、弧线等。
-Hough transform this program. Hough transform image processing image recognition from the basic geometry methods. The basic principle of Hough transform is to use point and line duality, the original image space curve given expression through the curve of the parameter space into a point. This had given the original image in the detection curve into a parameter space to find the problem in the peak. That is, the overall characteristics of the detection of local features into testing. For example, a straight line, oval, round, arc and so on. Platform: |
