Hi to everyone, currently I face this problem: I need to obtain ( .c ) versions of (extractHOGFeatures(x), extractLBPFeatures(x), rgb2hsv(x), imhist (x) ) functions which exist in computer vision toolbox. Because I need the same output of these Matlab functions to use it in android app. So is Matlab coder will help me?? Is it work well to convert these Matlab functions??

  • extractHOGFeatures - supported
  • extractLBPFeatures - supported
  • rgb2hsv - not supported (no HSV functions supported)
  • imhist - partial support (no display of image for example)
You can find the formula for rgb2hsv over here

Interesting, in the new release of R2016a, they made MATLAB Coder and Simulink Coder available as add-ons to Student Version... but they still did not make it available to Home license :(

i download matlab R2016a and matlab coder, and test it by very small function. matlab coder convert the function very well. then I try to convert extractLBPFeatures and extractHOGFeatures . a lot of errors occurs and I don't understand why. since these two functions are supported by matlab coder as mentioned in

thank you very much.. I check the errors and fix them ..the translation done.. but I need to test if it produce the same output of the matlab functions or not...
so I think that I have to install visual studio on my PC to test the generated code.
