Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

Making an image that was incorrectly saved as JPEG fit for saving as PNG; Suppose you have a map for an island that was inadvertently saved as JPEG. Looks OK, if a bit fuzzy. 1. In your bitmap graphics editor, set your fuzzy selection ("magic wand") tool so that it only will select pixels of exactly the same color. (Here: Threshold = 0) 2.
This format offers file compression ratios around 2:1 for lossless and 5:1 for visually lossless. The second main feature of Genuine Fractals is a scaling algorithm based on the use of PIFS (partitioned iterated function systems). When scaling up, Genuine Fractals exploits the self-similarity of an image to increase its size while preserving ...
Adobe Express, formerly Adobe Spark and later Creative Cloud Express, is a content creation tool developed by Adobe. [1] [2] [3] It is a cloud-based design platform where users can create videos, PDF documents, web pages, graphics and other digital assets. It is aimed at mainstream users, not professional graphic designers.
Examples of algorithms for this task include New Edge-Directed Interpolation (NEDI), [1] [2] Edge-Guided Image Interpolation (EGGI), [3] Iterative Curvature-Based Interpolation (ICBI), [citation needed] and Directional Cubic Convolution Interpolation (DCCI). [4] A study found that DCCI had the best scores in PSNR and SSIM on a series of test ...
Change the resolution to 800 ppi, and the same image now prints out at 2 × 1.5 inches. All three printed images contain the same data (1600 × 1200 pixels), but the pixels are closer together on the smaller prints, so the smaller images will potentially look sharp when the larger ones do not. The quality of the image will also depend on the ...
