[OpenCV image implementation: White balance algorithm using OpenCV image processing techniques]
Article directory summary Load sample image Statistical data analysis White Patch Algorithm summary Summary White balance technology plays a vital role in photography and image processing. Under different lighting conditions, the camera may not accurately capture the true color of an object, resulting in images that appear dull, unnatural in tone, or washed out. In […]

In-depth OpenCV Android application development
Preface OpenCV is the abbreviation of Open Source Computer Vision library (open source computer vision library). It is the most widely used computer vision library. Opencv is a collection of commonly used operating functions in the field of computer vision. It is written in C/C++ and also provides encapsulation of Python, Java and any JVM […]
linux C++ opencv image color space
In OpenCV, image color space conversion is a common image processing task. OpenCV provides a series of functions for converting between different color spaces. Here are some common color spaces and their conversion methods: Image color null purpose Different color spaces have their own advantages and uses in the fields of image processing and computer […]
OpenCV mouse action monitoring
cv2.setMouseCallback(winname, MouseCallback) is a monitoring function for the mouse status of the winname window. When there is a mouse action on the winname window, that is Automatically calling the MouseCallback function is equivalent to a mouse interrupt for this window. Before this function, there should be a corresponding window declaration function cv2.namedWindow(winname) to be captured […]
OpenCV implements gesture volume control
Foreword: Hello everyone, my name is Dream. Today let’s learn how to use OpenCV to implement gesture volume control. Everyone is welcome to come and discuss and learn~ 1. Introduction to required libraries and functions This experiment requires the use of OpenCV and mediapipe libraries for gesture recognition, and uses gesture distance to control the […]
