c++ vision—use the track bar to set the contrast and brightness of the picture
Track bar: cv::createTrackbar cv::createTrackbar is a function in the OpenCV library that creates a slider control in a graphical user interface (GUI) that allows the user to adjust the value of a specific parameter while the application is running. This function is called as follows: int cv::createTrackbar(const std::string & amp; trackbarName, const std::string & amp; […]
YOLOV5 data enhancement has these! —You can also add your own data enhancement methods (cropping, translation, rotation, changing brightness, adding noise)
Table of Contents 1 rectangular (convert rectangle width to height in the same batch to speed up training, minimize redundant black edges, and reduce the amount of calculations.) 2 HSV transformation 3. Random rotation, translation, scaling, cropping, miscutting/non-vertical projection, perspective transformation (starting from 0) 3-1 spin 3-2 Translation (src is the picture on the left, […]

STM32 controls the color and brightness of LED lights through Key
As the title says, use Keil uVision5 as the platform to control the brightness and color changes of the LED (red, green, blue, white cycle) through the GPIO register to STM32F103VE. Title and analysis Press KEY1 to control the LED light to switch between four modes: “red light – green light – blue light – […]
Unity3DAdjust screen brightness, saturation, contrast
1 screen post-processing process ? To adjust screen brightness, saturation, and contrast, you need to use screen post-processing technology. Therefore, this article will first introduce the screen post-processing process, and then introduce the implementation of adjusting screen brightness, saturation, and contrast. ? For the complete resources of this article, see →Unity3D adjust screen brightness, saturation, […]
Python realizes the angle of xml and json files, and enhances the brightness data set
Basic idea: use your own script, after making labels through labelImg or labelme, solve the problem of too few model training data sets. 1.
