What you'll learn

  • 学会使用opencv处理视频,并使用qt开发视频编辑器

Requirements

  • 有c或者c++基础的同学

Description

课程基于opencv 3.2讲解,全部使用最新的c++接口,旧的接口会逐步被opencv抛弃,所以我们学习还是尽量学习新的接口,QT使用最新的5.8版本,课程中会跨平台演示,所有代码都可以在windows和linux中编译,在windows中使用vs2013,linux中使用qtcreator,课程会提供全部源码和最新opencv和QT版本的下载。

    课程中讲解的opencv知识点,不追求全(全不如看手册),但求完整,讲解我们实战项目用到的函数方法,但凡是讲到的都要有一定的深度,分析其函数的实现、源码,有些我们自己也作出实现,课程的目标不是只能作出demo,而是要你能将opencv投入到实际项目中去。

     现在深度学习和人工智能热门,大量的技术涌现,单opencv作为老牌的图像视频库,一直是在大量的生产环境(包括嵌入式设备)中应用,不管你用什么深度学习的平台,opencv都是作为图像图像领域及佳的选择,可以很方便的与第三方深度学习框架结合 ,我公司项目中也一直在应用。

      课程中会讲解到基于opencv视频和摄像机录制、播放和播放进度控制,多视频图像合并、多视频图像融合、剪切、视频亮度、对比度、尺寸(近邻插值(手动实现),双线性插值,高斯金字塔,拉普拉斯金字塔)、颜色格式(灰度图,二值化(阈值)),旋转镜像,视频裁剪(ROI),视频水印(ROI+weight),导出处理后的视频(包含音频,使用ffmpeg工具对音频进行抽取、剪切和最终于opencv处理的视频合并)。

      课程中会讲解最热门的跨平台界面库QT5.8,用过或者学习过QT的人都知道这是c++程序员必须掌握的技能,包括现在热门的Python也是在大量的应用QT来做界面,QT的设计及其精美,他的信号槽机制很好的将界面与业务隔离开来,并且界面可以使用类似CSS的设置做得很炫(参考下图),不会像MFC一样自动生成的代码和你手写的代码融合在一起。当然我们也会仔细分析一下他的信号槽机制,你不理解他的机制会有很多坑等着你。

      课程中的实战视频编辑器会详细相机项目的设计架构图,提供全部源码,对实现进行迭代式讲解,就像你自己在做一个项目一样,最终完成所有的功能。

Who this course is for:

  • 从事视频图像方向研究生
