Use opencv to correct image distortion
1 Affine transformation 1.1 What is affine transformation In image processing, it is often necessary to perform various operations on images, such as translation, scaling, rotation, flipping, etc., which are all affine transformations of images. Image affine transformation, also known as image affine mapping, means that in geometry, a vector space is transformed into another […]
FreeRTOS_Direct Task Notifications
Directory title 1 Introduction 2. TCB members 3. Task notification API 3.1, simplified version 3.1.1, xTaskNotifyGive() 3.1.2, ulTaskNotifyTake() 3.2. Professional version 3.2.1, xTaskNotify() 3.2.2, xTaskNotifyWait() 1. Introduction When we use queues, semaphores, and event groups, we need to create corresponding structures in advance, and the two parties communicate through the intermediate structures. When using task […]
Depth-first search of directed graphs and dynamic selection algorithm of adjacency matrix
Introduction In graph theory, a directed graph is a graph structure with directional relationships between nodes. In practical applications, we often need to represent and operate directed graphs. In order to improve efficiency, we can dynamically select appropriate data structures for representation based on the size of the graph and the frequency of operations. Adjacency […]
Meta Pass generation of Shader’s indirect light in Unity
Article directory Preface The indirect light of Shader in Unity generates Meta Pass, which is also the content of global illumination GI. It is mainly implemented like in real life, when light shines on a colored object, the object has the effect of reflecting light of that color. 1. Let’s first use Unity’s own Shader […]

Java uses FTP cross-server dynamic monitoring to read file data in the specified directory
Background: 1. The file data is on server A (windows) (generated in the specified directory from time to time), and the project application is deployed on server B (Linux); 2. The project is applied on server B, monitors the directory specified by server A, and if there are newly generated files, reads the file information […]
