Canny of Dyeing

The "Canny of Dyeing" appears to be a typo or mishearing, possibly referring to the "Canning of Dyeing" or the "Canny Edge Detection" method in image processing. If you meant "Canny edge detection," it is a technique used in computer vision to identify and highlight the edges within an image. Essentially, it detects the boundaries of objects by highlighting areas where there is a sharp change in brightness or color. This process helps computers understand shapes, objects, and structures within images, enabling applications like facial recognition, medical imaging, and object detection.
