Loading an image using coder

I've got a simple function that processes a sequence of about 100-300 numbered jpegs to derive a single numerical value from each, and save the resulting 300 values in a csv file. I want to use the coder to translate it into c++ and compile it a stand-alone exe.

I've been through the code, taking out all the functions that don't feature on the list of those supported by the coder. But I'm stuck with imread . There seems to be no coder compatible equivalent available. I'm know I'm missing something as a substantial range of image processing functions have been implemented. And they surely must work on something .

Failing that, the solution seems to be to dust off my C skills and edit the coder-generated source by hand to load jpegs. But that surely isn't the way one's supposed to do it

imread doesn't support code generation. Consider writing C code to use libjpeg library to load jpg files. Alternatively, if you make an avi file out of their image files, vision.VideoFileReader generates standalone C code which relies on shared libraries. This means that the generated code will run only on platforms that MATLAB supports (think windows, linux, mac).
