OpenCV(Open Source Computer Vision Library)是一个用于计算机视觉和图像处理的开源库,提供了许多函数和方法以处理图像和视频。以下是一些常见的OpenCV函数和方法: 1. **图像读取和显示**: - `cv2.imread(filename)`: 读取图像文件。 - `cv2.imshow(window_name, image)`: 显示图像。 - `cv2.imwrite(filenam...
確認Include (.h) 和 Library (DLL) 檔案正在使用相同的資料夾位置。 確定輸出檔案的名稱正確,例如 superfastcode.pyd。 不正確的名稱或副檔名會阻止匯入必要的檔案。 如果您使用 setup.py 檔案安裝模組,請務必在為 Python 專案啟動的 pipPython 環境中執行指令。 當您在 Solution Explorer 中展開專案的活動 ...
示例代码:创建自定义Library 首先,创建一个名为my_math.py的文件,内容如下: # my_math.pydefadd(a,b):returna+bdefsubtract(a,b):returna-b 1. 2. 3. 4. 5. 6. 7. 接下来,在另一个Python文件中使用这个自定义库: # main.pyimportmy_math result_add=my_math.add(5,3)result_subtract=my_m...
