1. Reading and Displaying an Image with Alpha Channel import cv2 import numpy as np # Read the image with alpha channel img = cv2.imread(‘Cat_Small.jpg’, cv2.IMREAD_UNCHANGED) print(img.shape) # Display the image cv2.imshow(‘Image with Alpha Channel’, img) cv2.waitKey(0) cv2.destroyAllWindows() 2. Extracting Alpha Channel from an Image # Extract alpha channel alpha_channel = img[:, :, 2] # […]
3.1: Tensors Tensors are the central unit of data in TensorFlow. They are similar to arrays or matrices in other programming languages. A tensor has a data type and a shape. For example, a tensor can be one-dimensional (like a vector), two-dimensional (like a matrix), or even higher-dimensional. 3.2: Operations on Tensors TensorFlow provides a […]
https://youtu.be/uPJVHgn0PjU Image segmentation is a computer vision task that involves dividing an image into different parts or regions. Each of these regions represents a meaningful or semantically similar area. Here are the general steps involved in image segmentation: Image Acquisition: Obtain the image you want to segment through various means such as cameras, satellites, or […]

https://youtu.be/UHIJjYH9Zi4 Autograd, short for automatic differentiation, is a crucial component of modern machine learning frameworks like PyTorch, TensorFlow, and others. It enables automatic computation of gradients, which are essential for training machine learning models through techniques like gradient descent. Gradient: In the context of machine learning, a gradient represents the rate of change of a […]
https://youtu.be/WdBevhl5X0A?si=OtQowiw_3SgKke-0 1.1: What is PyTorch? PyTorch is an open-source machine learning library developed by Facebook’s AI Research lab (FAIR). It is primarily used for deep learning and is known for its flexibility, dynamic computation graph, and strong support for neural networks. PyTorch is based on the Torch library, and it provides a Python interface for […]
https://youtu.be/2deM80iuEYw In PyTorch, a tensor is a fundamental data structure that is used to represent multi-dimensional arrays. It is similar to NumPy arrays but has the added advantage of being able to run on GPUs, which makes it especially well-suited for deep learning and other machine learning tasks. Here are some key points about tensors […]
https://youtu.be/1JItKbpW24Y A color image, in the context of digital image processing, is an image that contains information about color. In most cases, color images are represented in the Red-Green-Blue (RGB) color model, where each pixel is a combination of three primary color channels: Red, Green, and Blue. Each channel represents the intensity or contribution of […]
