2. Unsharp masking - Wikipedia

   en.wikipedia.org/wiki/Unsharp_masking

   Unsharp masking applied to lower part of image. Unsharp masking (USM) is an image sharpening technique, first implemented in darkroom photography, but now commonly used in digital image processing software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The ...

3. Acutance - Wikipedia

   en.wikipedia.org/wiki/Acutance

   Acutance in the left line was artificially increased by adding a one-pixel-wide darker border on the outside of the line and a one-pixel-wide brighter border on the inside of the line. The actual sharpness of the image is unchanged, but the apparent sharpness is increased because of the greater acutance. Artificially increased acutance has ...

4. Image editing - Wikipedia

   en.wikipedia.org/wiki/Image_editing

   Image sharpening: original (top), image sharpened (bottom). Another form of image sharpening involves a form of contrast. This is done by finding the average color of the pixels around each pixel in a specified radius, and then contrasting that pixel from that average color. This effect makes the image seem clearer, seemingly adding details.

   One of the simpler ways of increasing the size, replacing every pixel with a number of pixels of the same color. The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest ...

   [6] [7] It has been used to teach students how to edit images. [8] Like Photoshop, it has layering capability, image adjustment tools such as changing the color balance, options for blending images, shadows and bevels, filters such as sharpening and blurring. [9]

7. Kernel (image processing) - Wikipedia

   For example, attempting to read a pixel 3 units outside an edge reads one 3 units inside the edge instead. Crop / Avoid overlap Any pixel in the output image which would require values from beyond the edge is skipped. This method can result in the output image being slightly smaller, with the edges having been cropped.
