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)
