Some codes may be different from what you said in you paper

[leoozy]

Hi, Thank you for your code. But I am confused about the "i" implemented in your code. I think it may be different from what you said in your paper. In your paper, you initialize "I" as :

In some filters, there may be more than one weight initialized as 1. But in your code:
dirac_(I)
you used dirac_ function to initialize it. Only one element in a filter could be set 1. Maybe I misunderstand it. Could you please help me with it?
