728x90 반응형 Computer Vision7 OpenCV + Python Edge detection and Hough transform Hello. This is codingwalks.Accurately detecting the boundaries of objects is utilized in various applications and is one of the core processes of image understanding. Edge detection is a representative method of boundary detection technology, and the technique used to find geometric shapes through the detected boundaries is Hough transform. Edge detection is the process of finding sudden changes.. 2024. 10. 25. OpenCV + Python Color recognition and drawing using a webcam (practical) Hello. This is codingwalks.The following is a color recognition and drawing exercise using a webcam. This mini-project uses OpenCV and Python to detect colors and create a simple program that draws points at the locations where the colors are detected to create a picture. We will proceed with the project step by step through theoretical explanations and Python code. 1. Project OverviewThe projec.. 2024. 10. 24. OpenCV + Python Crop and resize images Hello. This is codingwalks.Image resizing and cropping are some of the most basic and important tasks in image processing. In many fields such as web development, design, data analysis, and artificial intelligence, there are many cases where you need to resize an image or use only a specific part of it. In particular, in computer vision tasks, it is essential to optimize the size or remove unnec.. 2024. 10. 24. OpenCV + Python Angle Measuring Instrument (Practical) Hello. This is codingwalks.In this article, we will create a program that measures the angle between two lines on an image using Python and the OpenCV library based on what we have learned previously. We will explain in detail the process of defining two lines by clicking the mouse and calculating the angle using simple mathematical calculations, and provide examples with actual code. 1. Project.. 2024. 10. 23. OpenCV + Python Outputting Unicode Fonts Hello. This is codingwalks.Since OpenCV does not natively support outputting Unicode, additional work is required to output Unicode to an image. The most commonly used method for this is to use a TrueType font (TTF) file and draw Unicode to the image with the help of the Pillow (PIL) library. 1. Basic OpenCV text output functionIn OpenCV, you can annotate an image with text using the cv2.putText.. 2024. 10. 23. OpenCV + Python Various drawing functions and character output Hello. This is codingwalks.OpenCV is an image processing library that provides functions to easily draw various shapes and text on images. In this post, we will explain various functions for drawing lines and shapes (rectangles, circles, polygons, ellipses, etc.) and how to output text on images, and learn how to use them through example code. In order to easily implement a coordinate system for.. 2024. 10. 23. OpenCV + Python Introduction and installation process Hello. This is codingwalks.This course covers the introduction to OpenCV using Python. OpenCV is a representative library that can easily implement computer vision. Computer vision is a technology that analyzes and processes images, and can be used efficiently when used with Python. This course is designed for beginners to easily follow, and focuses on practice rather than theory. You will learn.. 2024. 10. 23. 이전 1 다음 728x90 반응형
