图像转灰度(Image to Grayscale)这个示例展示了如何使用Pillow库将彩色图像转换为灰度图像。我们定义了一个函数convert_to_grayscale,它接受图像路径和输出路径作为参数,转换图像并保存结果。#python应用 #数据分析 #编程 #Python练习 #自学编程 #人工智能 #Python编程 #Python入门 #Python教程0 0 发表

After converting to grayscale, adjust the contrast using Pillow’s ImageEnhance.Contrast() or OpenCV’s cv2.equalizeHist() to retain more details in the image. This approach is especially effective for images with subtle color differences that may lose detail during grayscale conversion. Integrate...
