A software method of exaggerating edges in an image to give enhanced definition.
In a video camera, a special algorithm that is applied to the video image to make it sharper. With too much sharpening, strange artifacts will appear in the image.
Sharpening is a software routine used to enhance detail in a CCD image. There are numerous methods employed for sharpening images--there are even whole programs dedicated only to sharpening. Some are simple sharpening routines, while others involve more complex algorithms (such as the unsharp mask technique), and some employ iterative routines to produce successively sharper images while attempting to minimize the noise inherently generated in sharpening (the Lucy-Richardson and similar techniques).
Sharpening is a tool used within the digital world. It is used to enhance "sharpen", the detail of an image and separate the light and dark tonings across an image.
The emphasis of edge information in an image. Compare with blurring.
Increasing the apparent sharpness of an image by increasing the contrast between the adjacent tones or colors. Smoothing - To blur the boundaries between tones of an image, usually to reduce a rough or jagged appearance.
Increasing the optical illusion of sharpness of an image by increasing the contrast between the adjacent tones or colors. Sharpening cannot create details beyond the resolution of the image, but it brings out the captured detail.
An image processing operation that enhances edges. A non-sharp mask adds a low-pass, filtered image to the original, resulting in edge enhancement.
Sharpening is the process of creating or refining a sharp edge on a tool or implement. The term has a wide application but can be expressed as the creation of two intersecting planes which produce an edge that is sharp enough to cut through the target material. For example, the blade of a steel knife is ground to a bevel so that the two sides of the blade meet.
