VideoDetect
- 基于OpenCV的简易目标检测跟踪程序,能够实现对每帧视频的连续编号截图,可以实现键盘对视频播放的控制,能对每一视频帧生成包含运动目标区域的前景图像,采用某种策略实现对运动目标的跟踪,并用矩形框+编号将运动目标标出。-A simple target detection program base on OpenCV , which can numbered consecutively for each frame of video screenshots, keyboard control the
opengl_qt_texture_mapping
- 纹理映射简单的讲,就是把一个纹理(其实说白了,纹理可以理解为一幅图像)映射到空间物体的表面上,因此纹理映射也叫贴图,这个表明不一定是矩形,比如说我可以是球面,或者是任意曲面。在上一篇文章OpenGL_Qt学习笔记之_04(3D图形的绘制和旋转)中,我们绘制的空间体的表面都是一些光滑的颜色,如果要在其表面采用那种方法绘制图像的话,则必须利用微分的思想,一个一个的绘制小图像,然后拼接起来,可想而知,这个过程是多么的复杂,opengl的纹理映射就可以很好的解决这一问题。 这个实验室在上一篇博文Op
