Numpy Python Sum Absolute Value From File Stack Overflow
You can simply use NumPy functions to get the desired result np sum np abs np diff time This works according to your desired formula even though np diff calculates the difference time i 1 time i instead of time i time i 1 because you re using the absolute value

What Is Numpy And Used For Introduction To Numpy
Explanation This is extremely simple Here the input to the Numpy absolute value function is a negative number 5 When we provide this value as the argument to the function np abs simply computes the absolute value which is 5 To be clear you could also run this code as np absolute 5 It s effectively the same as Numpy Absolute Value Explained Sharp Sight. Essentially the NumPy sum function sums up the elements of an array It just takes the elements within a NumPy array an ndarray object and adds them together Having said that it can get a little more complicated It s possible to also add up the rows or add up the columns of an array But I guess you should be able to do m1 np array img1 getdata m2 np array img2 getdata dif np sum np abs m1 m2 without any loops at all You don t need to separate bands to compute absolute differences Cris Luengo Sep 28 2018 at 19 08 1 Take a step back What are you trying to achieve
