Lec01 | Introduction#

What is Computer Vision#

A standard computer vision system:

Computer vision tasks#

  • 3D reconstruction
    • 3D reconstruction, localization, SLAM，……
  • Image undestanding
    • Image recognition, object detection, image segmentation, action recognition, deep learning,……
  • Image synthesis
    • Colorization, super-resolution, debluring, HDR, panorama, free-viewpoint, GANs, ……

Why is computer vision hard?#

  • computers can be better at computing
  • humans are better at understanding

Linear Algebra Recap#

矩阵和向量的乘法表示对向量位置进行几何变换，矩阵的列描述了该变换的具体形式（标准基经变换后的坐标）

从几何角度理解矩阵可逆：变换前后的两个点一一对应

行列式几何意义：The determinant is the volume of an n-dimensional parallel body

Application of Eigenvalues and eigenvectors#

  • Principal components analysis(PCA)
