What s the fastest way to threshold a numpy array
Method 1 use np where np where arr threshold 255 0 array 255 255 255 255 0 255 255 0 255 Method 2 use boolean indexing to create a new array up arr threshold new arr np zeros like arr new arr up 255 Method 3 do the same but use an arithmetic hack
Python threshold in 2D numpy array Stack Overflow, One solution result array 25 array The first part array 25 gives you an array of the same shape that is 1 True where values are less than 25 and 0 False otherwise Element wise multiplication with the original array retains the values that are smaller than 25 and sets the rest to 0 This does not change the original array
