MATLAB: Image as function input

Question

Hello

I have the SIFT_feature script from https://nl.mathworks.com/matlabcentral/fileexchange/50319-sift-feature-extreaction , but there is an image defined in the function itself.

In my script I'd like to use the SIFT_feature on defined images as shown below:

so in other words, I'd like to use the function SIFT_feature on my defined image E. This however, does not work since the function looks liks this:

Since I'm not that familiar with coding nor matlab, is there a way I can use an image defined in my script as input for the function? I experimented a bit with the SIFT_feature(img,origin) of the function but none of it seems to work.

Thanks in advance

Answer 1

Get rid of the "clear" in that function, after the tic statement.

That clear is deleting whatever you passed in for img and origin via the input argument list.
