Certain Image Processing Toolbox™ functions have been enabled to generate C code using MATLAB® Coder™. To use code generation with image processing functions, follow these steps:
Write your MATLAB function or application as you would normally, using functions from the Image Processing Toolbox.
Add the %#codegen compiler directive to your MATLAB code.
Open the MATLAB Coder app, create a project, and add your file to the project. Once in MATLAB Coder, you can check the readiness of your code for code generation. For example, your code may contain functions that are not enabled for code generation. Make any modifications required for code generation.
Generate code by clicking Build on the Build tab of the MATLAB Coder app. You can choose to build a MEX file, a shared library, a dynamic library, or an executable.
Even if you addressed all readiness issues identified by MATLAB Coder, you might still encounter build issues. The readiness check only looks at function dependencies. When you try to generate code, MATLAB Coder might discover coding patterns that are not supported for code generation. View the error report and modify your MATLAB code until you get a successful build.
For more information about code generation, see the MATLAB Coder documentation. To see an example of using code generation, see Generate Code from Application Containing Image Processing Functions.
When working with generated code, note the following:
For some Image Processing Toolbox functions, code generation depends on a precompiled, platform-specific shared library.
