Numpy threshold, Learn from the basics to implementing IoU from scratch
Numpy threshold, clip() function limits the values in an array to a specified range. Apr 10, 2024 · Alternatively, you can use a list comprehension. As this is quite a simple operation, maybe there is a numpy function that does it in an efficient way, but I've been unable to find it. where. array(range(10)) # testing data b = numpy. array(filter(lambda x: x >= threshold, a)) The problem is that this creates a temporary list, using a filter with a lambda function (slow). The first argument is the condition (values greater than the threshold), the second argument is the value to set for True condition (255 for white), and the third argument is the value to set for False condition (0 for black).
