'How to obtain unit gradient vector image python?
I am trying to obtain the correct image for the unit gradient vector calculations. I am working with retinal images. Here is the code that I have used to try and obtain the correct image along with the formula that I am trying to implement.
Nx = arrayx_cropped/np.sqrt(arrayx_cropped**2 + arrayy_cropped**2)Ny = arrayy_cropped/np.sqrt(arrayx_cropped**2 + arrayy_cropped**2)
Whenever I run this formula the following warning message appears: Runtim
Ny = arrayy_cropped/np.sqrt(arrayx_cropped**2 + arrayy_cropped**2)
The resulting image that I obtain is this: This is the image obtained for using the unit gradient formula in the x direction using equation 1)
Again help or advice on how to go about starting to resolve this issue would be greatly appreciated.
