Dynamic input to the gpu cuda kernel generated from gpu coder application

The follwing code contains two operations. CLAHE and color conversion. It was like enabling two different operation in the input video stream. So, i need one varible to enable clahe alone, color conversion alone and both can be enabled at the same time. In normal QT application this was controlled by button click operation. So if i didnt enable the clahe the output stream should be original image or bnb enabled image.
The parameter in the adapthist 'clip limit' and 'tile size' change during the run time.

% Main loop

for k = 1:10000

% Capture the image from the camera on hardware.

img = snapshot(camObj);

%img = imcrop(img,[0 0 400 400]);

img = imcrop(img,[0 0 400 400]);

////////// Need to select CLAHE MODE ///////////////////

% Convert rgb to lab

lab = rgb2lab(img);

L = lab(:,:,1);

L = L/100;

CLAHE = adapthisteq(L,'NumTiles',[8 8],'ClipLimit',0.001);

lab(:,:,1) = CLAHE*100;

rgb_result = lab2rgb(lab);

rgb_result = uint8(rgb_result*255); ///out_img is rgb_result

/////// need to select the color conversion mode /////////

g = zeros(400,400,3);

%g = zeros(720,1280,3);

g(:,:,1) = 0.05 * rgb_result(:,:,1);

g(:,:,2) = rgb_result(:,:,2);

g(:,:,3) = rgb_result(:,:,3);

HSV = rgb2hsv(g);

HSV(:,:,1) = mod(HSV(:,:,1)-0.33,1);

g3 = hsv2rgb(HSV);

g3(:,:,1) = 0.85*g3(:,:,1);

g3(:,:,3) = g3(:,:,2);1 ////out_img is g3

end

Thanks in advance

Hi Gayathri,

Apologies for the delayed response. Thank you for additional details.

GPU Coder has sevaral examples demostrating how to use various features of the the tool. Here is the link https://www.mathworks.com/help/gpucoder/getting-started-with-gpu-coder.html

It looks like you are looking for ways to pass input to your function. There is nothing specific needs to be done for GPU Coder. One can achieve this by defining a MATLAB function and passing necessary input as arguments, and then generating code for the function. Please take a look at this example for more details.
