OpenCV Edge Detection ( cv2.Canny ) In the first part of this tutorial, we’ll discuss what edge detection is and why we use it in our computer vision and image processing applications. We’ll then review the types of edges in an image, including: ...
Edge Detection is a fundamental image processing technique which involves computing an image gradient to quantify the magnitude and direction of edges in an image. Image gradients are used in various downstream tasks in computer vision such as line detection, feature detection, and image classification...
1.A method of compensating for distortion at an edge of an image during image processing, said method comprising:detecting the edge in the image; andsharpening the detected edge, wherein the degree of sharpening is directly proportional to a degree of distortion in the image. ...
