Learn image gradients, image boundaries, etc. The functions used are cv2.Sobel(), cv2.Schar(), cv2.Laplacian(), and so on. principle The_gradient is simply derivation, and OpenCV provides three different gradient filters, or high-pass filters: Sobel, Scharr, and Laplacian.Sobel, Scharr actually implements the first or second derivatives.S ...

The fourth picture makes spark, because there is spark interference in the welding process, and it has a great impact. Sparks have a great influence on the image. Large sparks directly affect some characteristics of steel plate. My first idea is to use contour extraction to calculate the contour area. In a certain range, I think that the ...

background Recently, OpenCV, a code related to image recognition, has been studied. To facilitate debugging, a debugging environment for debugging c++ programs on Mac has to be set up.I'm running away. Share it with you.

Today let's look at how OpenCV3 operates on images. Image operations are mainly based on various coordinate transformations of images, such as scale transformation, rotation transformation, translation transformation and offset transformation (horizontal or vertical). These transformations are all directed at the coordinates of images, not the ...

Preface After dozens of caffe installation experiences, I finally have a deeper understanding of its installation process and know how to avoid some bug s. Let me restart it first. If we can get into ubuntu normally, let's describe the configuration process in detail. (Because the previous configuration was successful, even ub ...
