DetectSurfFeatures函数是一个MATLAB函数,用于检测图像中的SURF特征。它的基本原理是在给定图像的每个像素点上检测特征,以标识特征点,并衡量每个点的稳定性。SURF特征的计算依赖于形状,灰度强度以及梯度信息,因此它非常适合用于检测简单特征,例如角点,边缘和局部变化点(如纹理)。 根据函数声明,DetectSurfFeatures的函数格式...

thank you.It worked. although the image was in grayscale i had to convert it once againg using rgb2gray fn and the code works now.return
