求一个图像的最大内接矩形面积。
步骤:
1.相机标定。首先根据物像关系式求出其中的参数。注意参数求出后要进行参数校验。
2.从背景中分离出目标
3.边缘检测
4.目标形状参数计算。-For an image of the largest inscribed rectangle area. Steps: 1. Camera calibration. First of all object-image relationship in accordance with the par

Gabor滤波器经常被用于形状检测和特征提取,比如增强指纹图像。本代码用matlab实现了一个二维Gabor滤波器。
代码使用如下:
function [G,gabout] = gaborfilter1(I,Sx,Sy,f,theta)
from gaborfilter1 with different f(Frequency) and theta(Angle).
for example
f:0,2,4,8,16,32
theta = 0,pi/3,pi/6

激光雷达是以发射激光束探测目标的位置、速度等特征量的雷达系统。从工作原理上讲,与微波雷达没有根本的区别:向目标发射探测信号(激光束),然后将接收到的从目标反射回来的信号(目标回波)与发射信号进行比较,作适当处理后,就可获得目标的有关信息,如目标距离、方位、高度、速度、姿态、甚至形状等参数,从而对飞机、导弹等目标进行探测、跟踪和识别。本程序为FMCW激光雷达matlab程序,包括调频非线性校正等。-Laser emitting a laser beam radar detection is the
