Answer:
edge enhancement
Step-by-step explanation:
- Edge Improvement is an image processing filter that enhances the edge contrast of an image or video in an effort to improve its sharpness.
- Edge enhancement does not enhance subtle details found in more uniform areas of the image, such as texture or grain appearing in flat or smooth areas of the image.
- The filter works by marking the sharp edge boundaries of the image, the edge between a subject and the contrasting color background, and increasing the image contrast in the area around the edge.
