Not enough arguments error in simulink model

Hi, I have created a simple model to process two images to detect features, and output distance estimates between matching features. The model has two spurces from corresponding files, Image 1 and Image 2. Each image is converted to RGB, and input to a function block I have defined as v= functionKAZE(grayImg1, grayImg2). This function block is linked to a scope showing v vs. time.

When I run this model, simulink responds with the error message "Not enough input arguments.". I have checked my function separately with the image files supplied from the command prompt, and works fine. What could I have missed? Thanks In advance.

Hi @Araya Mengistu,

To better understand the issue, it would be better if you can share the Simulink model and any other files that may be required to run your model.

Thanks for the reply. I managed to identify the issue and resolve.
