In this issue, the editor will bring you about how to use OpenCV custom linear filtering in C++. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Code demonstration

Create a new project opencv-0015, configure properties (VS2017 configure OpenCV common properties), and then write # include and main methods in the source file

Robert operator

The above image represents the x-axis direction and y-axis direction of the Robert operator.

Let's first calculate the X-axis direction.

The x-axis direction operator is added to the code. Press the l key to deal with the setting. Let's see the effect.

Then let's take a look at the y-axis processing.

Running effect

Sobel operator

The Sobel operator is the convolution of 3X3, which is also divided into X and Y directions. We write the code of X and Y directly.

Look at the effect of the display.

X direction effect

Y direction effect

Laplace operator

Go directly to the code
