Application of Morphological Methods in Poker Card Recognition

Playing card recognition is one of the important research directions in the field of computer vision. Among them, the morphological method is a commonly used image processing technology that can be used to extract and identify the characteristics of playing cards. This article introduces the morphological poker card recognition method based on MATLAB and provides the corresponding source code.

1. Image preprocessing
   First, the input playing card image needs to be preprocessed. Common preprocessing steps include image grayscale, binarization, denoising, etc. Below is a sample MATLAB code:

% 图像读取
image = imread('poker.jpg');

% 灰度化
grayImage = rgb2gray(image);

% 图像二值化
threshold = graythresh</
