Image pattern recognition: MATLAB realizes the detection of circles, squares and rectangles
In the field of computer vision, image pattern recognition is an important research direction. As a high-level programming language and environment, MATLAB provides a wealth of image processing and analysis tools, which can easily implement image pattern recognition algorithms. This article will introduce how to use MATLAB to detect circles, squares and rectangles in images, and give the corresponding source code and description.
First, we need to load the image and preprocess it. In MATLAB, you can use the imread function to load an image, and use the imresize function to resize the image for subsequent processing. In addition, in order to better process the image, it can be converted into a grayscale image, using the rgb2gray function. The following is the specific code:
% 加载图像
image = imread('image.jpg');
% 调整图像大小
resizedImage = imresize(image, [
