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] # […]
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 […]
Utility functions for images refer to mathematical functions or algorithms that are designed to evaluate or measure various aspects of an image’s quality, content, or characteristics. These functions are often used in image processing and computer vision applications to perform tasks such as image analysis, enhancement, compression, or evaluation. Here are some common utility functions […]
Manipulating pixels in images refers to the process of making changes to individual pixels within a digital image. Each pixel in an image represents a tiny unit of color and contributes to the overall appearance of the image. Manipulating these pixels allows you to perform various image processing tasks, such as adjusting colors, enhancing details, […]
An image can be represented as a matrix, where each element of the matrix corresponds to a pixel in the image. The values in the matrix represent the intensity or color of each pixel. In this documentation, we will explain how to represent an image as a matrix and discuss important points related to this […]
A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels. Pixel values typically represent gray levels, colors, and intensities of light. Digital images are used in a variety of applications, including computer vision, medical imaging, and digital photography. Definition of Digital Image: A […]
Images are everywhere, from the photographs we take with our smartphones to the visuals we see on our computer screens. But how exactly are these images formed? This documentation will delve into the science and mechanics behind image formation, explaining the process step by step. Introduction to Light: The formation of images is primarily a […]
Introduction: Computer vision is a field of artificial intelligence that enables computers to interpret and understand visual information from the world, such as images and videos. Despite significant advancements, there are still numerous challenges that need to be addressed to improve the accuracy and efficiency of computer vision systems. Data Quality and Quantity: One of […]
ou can display and save images in Python using various libraries. One of the most commonly used libraries for working with images is Pillow (PIL), which is a fork of the older Python Imaging Library (PIL). Here are examples of how to display and save images using Pillow: Displaying an Image: from PIL import Image […]
https://youtu.be/IdpmVNAnRWo?si=Df6Tp333hlZBlUVY Image Processing and Computer Vision are two closely related fields that often overlap, but they have distinct goals and methodologies. This document will provide a comprehensive overview of both fields, highlighting their differences and similarities, and explaining the important steps involved in each process. Definition: Image Processing: Image processing is a method to perform […]
