C# OpenCvSharp uses Lab space to change the spring scene to autumn

Table of Contents Effect project code download Effect project VS2022 .net framework 4.8 OpenCvSharp 4.8 code Lab color space is a color model that contains three components: brightness (L), red and green channels (a), and blue and yellow channels (b). By converting the image from BGR to Lab, the color information can be separated into […]

Use opencv to combine frame difference method and background subtraction to detect scene anomalies

1. Frame difference method to detect abnormalities Frame subtraction is a simple background subtraction technique used to detect the difference between the current frame and the background frame. The following is an example of Python code using OpenCV to implement the frame difference method: import cv2 # Read the background image (the background should be […]

Self-built data set, developed and built a weed detection and identification system in farmland scenes based on YOLOv7

In some of our previous articles, we have also done a lot of testing projects related to agriculture. If you are interested, you can read it by yourself. Here are only the two most recent ones: “How far is laser weeding from our actual agricultural life? A field crop weed detection and identification system was […]

Backpack system based on SqLite storage + full process of picking up objects in the scene

Zero, functional analysis For the backpack system, we first need to implement several key functions: 1. Persistent storage of item data 2. Clear display of items 3. For convenient management of items, you can add and delete items 4. How to pick up items in the scene 1. Persistent storage based on SqLite The backpack […]

3D twin scene construction: simulation

The previous articles introduced how to use the NSDT editor to build 3D application scenes. This issue introduces one by one very important functions in the twin scene: simulation. 1. What is simulation SimulationSimulation is a type of computer models and programs used to describe, analyze, and simulate real-world systems, processes, or events. Simulation generates […]
