12月6每日打卡
实验二：百度图像增强与特效SDK实验
一、实验要求
任务一：下载配置百度图像增强与特效的Java相关库及环境（占10%）。
任务二：了解百度图像增强与特效相关功能并进行总结（占20%）。
任务三：完成图像增强GUI相关功能代码并测试调用，要求上传自己的模糊照片进行图像增强（占30%）。
任务四：完成图像特效GUI相关功能代码并测试调用，要求上传自己的照片进行图像特效（占30%）。
实验总结：（占10%）
二、实验步骤
任务一：
任务二：
百度图像增强与特效是百度提供的一项人工智能服务，它可以通过应用各种图像处理算法对图像进行增强和添加特效，以改善图像的质量和视觉效果。以下两种是我用到百度图像增强与特效功能的总结：
- 图像增强：百度图像增强服务提供了多种图像增强技术，包括亮度增强、对比度增强、锐化等。这些技术可以使图像更清晰、更鲜明，并提高图像的可视性。
- 图片动漫化：图片动漫化是一种将真实照片或图像转换成类似动漫风格的艺术效果的过程。这种效果通常包括对图像进行线条加粗、颜色处理和光影效果等，使图像看起来像是从动漫或漫画中提取出来的。
