- 对二值图像边界进行跟踪，对边缘进行判断，然后沿着边缘进行跟进- C = CONTOUR_FOLLOWING(BW) takes BW as an input. BW is a binary array containing the image of an object ( 1 : foreground, 0 : background). It returns a circular list (N x 2, C(1,:)=C(end,:)) of the (row,co

- 针对非圆信号DOA估计问题,提出了一种基于实值特征值分解 (Eigenvalue decomposition,EVD)的求根MUSIC算法.首先利用非圆信号为实值信号的特点,将阵列上的接收数据及其共轭用欧拉公式转换为实值正弦与 余弦数据,然后将正弦与余弦数据进行串联,从而扩展了数据维数.由于采用实值矩阵的EVD,因此在EVD阶段的运算量简化为复值EVD的1/4.根据 EVD后获得的信号与噪声子空间的特点,对噪声子空间和导向矩阵进行重构以便于可以使用求根MUSIC算法获取对DOA的估计.仿真实验验
