detectsurffeatures函数 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,...
Example:detectSURFFeatures(I,'MetricThreshold',100) MetricThreshold—Strongest feature threshold 1000.0(default) |non-negative scalar Strongest feature threshold, specified as a non-negative scalar. To return more blobs, decrease the value of this threshold. ...
DetectSURFFeatures Function: An Overview DetectSURFFeatures is a function in MATLAB that is used to detect the scale-invariant feature transform (SIFT) features in an image. SIFT features are used in computer vision and image processing to identify and match objects in images. The function is pa...
i am having following sample code: I = imread('box.jpg'); points = detectSURFFeatures(I); 테마복사 imshow(I); hold on; plot(points.selectStrongest(10)); i am getting this error: Error using detectSURFFeatures Expected input number 1, I, to be two-dimensional....
well, 'detectSURFFeatures' is not available. How to get it. I use Matlab in school and its completely legal and purchased version. Please reply as early as possible. 0 Comments Sign in to comment. Sign in to answer this question.Accepted...

points = detectSURFFeatures(I) returns a SURFPoints object, points, containing information about SURF features detected in the 2-D grayscale input image I. The detectSURFFeatures function implements the Speeded-Up Robust Features (SURF) algorithm to find blob features. points = detectSURFFeatures(...
function pts=detectSURFFeatures(Z,varargin); hold on; It is showing error as One or more output arguments not assigned during call to 'C:\MATLAB7\work\detectSURFFeatures.m (detectSURFFeatures)'. how should i define in script?? 0 Comments Sign in...
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
