Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness). The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge. This has the effe… WebApr 9, 2024 · Image processing is a key component of industrial automation, as it enables machines to acquire, analyze, and act on visual data from cameras, sensors, or …
