python --opencv image processing Canny operator edge detection (Roberts operator, Prewitt operator, Sobel operator, Laplacian operator, Scharr operator, LOG operator)

edge detection Edge detection is a common method of image segmentation based on gray level mutation. Its essence is to extract the features of discontinuous parts in the image. At present, the common edge detection operators include difference operator, Roberts operator, Sobel operator, Prewitt operator, Log operator and Canny operator. Amon ...

Build an online image processing server using flash

Task description The robot needs to take pictures and obtain detection results during operation. The computer processing on the robot is too slow, so it wants to put the image processing program on the server. When the robot needs detection, it sends the captured images and processing requirements to the server. After processing, the server sen ...

Introduction to OpenCV -- image smoothing technology

About image sampling There are many ways to obtain digital images. Usually, image sampling can be used to digitize continuous images. The collection relationship between sampling points is the grid, and the infinitesimal sampling points between grids correspond to the pixels in the image. Sampling on image transformation is the process of cha ...

python OpenCV drawing function

OpenCV can be used to draw different collection graphics, including lines, rectangles, circles, ellipses, polygons and adding text to images. The drawing functions used include CV2 line(),cv2.circle(),cv2.rectangle() ,cv2.putText() and so on. These drawing functions need to set parameters, such as: • img: the image you want to draw. & ...
