Description: 菱形搜索算法是在四步搜索算法的基础上采用菱形搜索路线得到的一种算法。它充分考虑了现实中的物体在水平和垂直这两个方向运动的概率比较大，图像的频谱多呈菱形。菱形搜索算法采用了两种搜索模式：大菱形搜索模式（LDSP）和小菱形搜索模式（SDSP）[6]。LDSP有一个中心点和它周围的8个搜索点构成，这九个点组成一个菱形，SDSP由5个搜索点构成-Diamond search algorithm in the four-step search algorithm based on the use of diamond-shaped search route received an algorithm. It takes full account of the reality of the objects in the horizontal and vertical direction of movement of both the probability of relatively large, mostly diamond-shaped image of the spectrum. Diamond search algorithm uses two search modes: large diamond search pattern (LDSP) and small diamond search pattern (SDSP) [6]. LDSP there is a focal point and its surrounding eight points, english composition, the nine points of a diamond, SDSP by five points constitute english
