random.ranf() # numpy.random.ranf() is one of the function for doing random sampling in numpy. It returns an array of specified shape # and fills it with random floats in the half-open interval [0.0, 1.0). import numpy as np # output random float value out_val = np.random.ranf()...

Using bitwise operators such as AND, OR, and bit-shifts, in our compressed representation of the events, we establish expressions for each of Allen’s relations. Our experiments show that, for two events with roughly 5×106 intervals in each, the bitwise operation-based methods are almost 42...

Bitwise operators are used in OpenCV so that we can extract or filter out the part of an image, portraying the image and operating with non-rectangular ROIs (Region of Interest). Use Bitwise AND Operator on Images in OpenCV In OpenCV, the Bitwise AND operator is used to combine two differ...

Whenever we are dealing with images while solving computer vision problems, there arises a necessity to wither manipulate the given image or extract parts of the given image based on the requirement, in such cases we make use of bitwise operators in OpenCV and when the elements of the arrays ...
Implementing OpenCV AND, OR, XOR, and NOT bitwise operators In this section, we will review four bitwise operations: AND, OR, XOR, and NOT. While very basic and low level, these four operations are paramount to image processing — especially when working with masks later in this series. ...
