Over the past few years, image processing users have seen performance enhancements in MATLAB math functions and Image Processing Toolbox functions. Since Release 2008a, MATLAB has incorporated major performance improvements to some of the math engines that underlie its matrix mathematics. T...
In generated code, each supported toolbox function has the same name, arguments, and functionality as its Image Processing Toolbox counterpart. To use code generation with image processing functions, follow these steps: Write your MATLAB function or application as you would normally, using functions...
Learn how to generate C code from Image Processing Toolbox™ functions using MATLAB® Coder™. GPU Code Generation Workflow (GPU Coder) Design, implement, and verify generated CUDA MEX for acceleration and standalone CUDA code for deployment. Integrate YOLO v2 Vehicle Detector System on So...

However, for many image processing applications we still need to write our own code, either in MATLAB or, in the case of GPU-accelerated applications requiring specific control over GPU resources, in CUDA (Nvidia Corporation, Santa Clara, CA, USA). In this chapter, the first part is ...
