cv.split() is a costly operation (in terms of time). So use it only if necessary. Otherwise go for Numpy indexing. Making Borders for Images (Padding) If you want to create a border around an image, something like a photo frame, you can usecv.copyMakeBorder(). But it has more appli...
Operations on a 2D Array Arithmetic Operators with Numpy 2D Arrays Let’s create 2 two-dimensional arrays, A and B. A = np.array([[3,2],[0,1]]) B = np.array([[3,1],[2,1]]) And print them: print(A) Output: [3 2] [0 1] ...
Broadcasting is a key NumPy behavior that allows for efficient operations on arrays of different sizes. Simply put, it allows for arithmetic operations between arrays of different sizes by ensuring both arrays have compatible shapes. This is done when NumPy automatically replicates smaller arrays across...
🐛 Describe the bug When I try to run the following simple piece of code: import numpy as np import torch np.random.seed(42) x = torch.from_numpy(np.random.rand(100)).float() print(x) exp_x = torch.exp(x) print(exp_x) I get a floating poi...

NumPy is a key Python library for numerical operations. It simplifies and speeds up this process. In this article, we will explore several functions for basic statistical analysis offered by NumPy. NumPy is a Python library for numerical computing. It helps with working on arrays and mathematical...
Basic Image Operations With the Pillow Library. The Pillow library is a fork of an older library called PIL. PIL stands for Python Imaging Library, and it’s the original library that enabled Python to deal with images. PIL was discontinued in 2011…
