Chapter 24 image and video processing based on Simulink -- matlab in-depth learning and practical collation

Simulink Is the U.S. Mathworks company-launched MATLAB A visual simulation tool in .Simulink Is a module diagram environment , For multi domain simulation and model-based design . It supports system design 、 Simulation 、 Automatic code generation and continuous testing and verification of embedded systems .Simulink Provide graphic editor 、 Customizable module library and solver , Capable of dynamic system modeling and simulation , Powerful , It has a wide range of applications .

See above . Application of optical flow field .

Model carrying process

Model features ：

1. A rich and extensible Library of predefined modules

2. Interactive graphic editor to combine and manage intuitive module diagrams

3. Divide the model with the hierarchy of design functions , Realize the management of complex design

4. adopt Model Explorer Navigation 、 establish 、 To configure 、 Search for any signal in the model 、 Parameters 、 attribute , Generate model code

5. Provide API For connection with other emulators or integration with handwritten code

6. Graphical debugger and parser to check simulation results , Diagnose design performance and abnormal behavior

7. Accessible MATLAB So as to analyze and visualize the results , Customize the modeling environment , Define signal parameters and test data

Here are the first 300 lines of code for the model ：
