基于python的图像3通道检测，使用openCV-cv2实现，运行结果输出非3通道图片路径。import osimport numpy as npimport cv2if __name__ == '__main__': root_dir = r'D:\...' label = [] label_an = [] name = root_dir.split('\\')[-1] file_names = sorted(os.listdir(root_

【从零学习OpenCV 4】图像透视变换高斯模糊（高斯滤波）的原理与算法

Problem location: 在训练的图片集中，混入了几张4通道的图片，将这几张图片删除后问题解除。使用cv2中img.shape列出非3通道图片的文件名：import osimport numpy as npimport cv2if __name__ == '__main__': root_dir = r'D:\WData\Workspace\springdemo\images\table_images\1.0\all_table' name = root_di
