The Kopf–Lischinski algorithm is a novel way to extract resolution-independent vector graphics from pixel art described in the 2011 paper "Depixelizing Pixel Art". [23] A Python implementation is available. [24] The algorithm has been ported to GPUs and optimized for real-time rendering. The source code is available for this variant. [25]
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.
Today, machine-made paper may artificially have its edges produced with deckle edges. [2]: 456, 458 The deckle could not make a perfect seal against the screen at the edges and the paper slurry would seep under, creating a rough edge to the paper. The deckle edge could be trimmed off, but this extra step added to the cost of the book.

The in-camera effect, as well as beginner tutorials given for software like Photoshop or GIMP, use a simple tint. More sophisticated software tends to implement sepia tones using the duotone feature. Simpler photo-editing software usually has an option to sepia-tone an image in one step.
In printing, bleed is printing that goes beyond the edge of where the sheet will be trimmed. In other words, the bleed is the area to be trimmed off. The bleed is the part on the side of a document that gives the printer a small amount of space to account for natural movement of the paper during guillotining, [1] and design inconsistencies ...
A hand-made piece of flax paper that has been pressed, but has not dried yet. A deckle is a removable wooden frame or "fence" used in manual papermaking. The deckle is placed into a mould to keep the paper pulp slurry within the bounds of the wire facing on a mould, and to control the size of the sheet produced.
Book trimming is the stage of the book production process in which the page edges of a book are trimmed so that all pages will stack with perfect edge alignment within the finished book jacket. The step before book trimming is the binding of the folded printing sheets.
