What is color edge detection?
in color images. Edge detection is one of the most important tasks in image processing and scene analysis systems. It denotes the procedure of detecting meaningful discontinuities (edges) of the image function (see Figure 1 for an example of edge detection in color and gray-level image).
How the edges are detected from image?
Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.
What is color detection in image processing?
A color detection algorithm identifies pixels in an image that match a specified color or color range. The color of detected pixels can then be changed to distinguish them from the rest of the image.
What is used to OpenCV is used to detect edges of the image?
In this article, the popular canny edge detection algorithm is used to detect a wide range of edges in images. OpenCV has in-built function cv2. Canny() which takes our input image as first argument and its aperture size(min value and max value) as last two arguments.
