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.
In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement .
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-neighbor interpolation. Other scaling methods below are better at preserving smooth contours in the image.
Enlarger lens: using the aperture ring, the photographer adjusts the iris diaphragm. The image from the negative or transparency is projected through a lens, typically fitted with an adjustable aperture marked with f/ stops, onto a flat surface bearing the sensitized photographic paper. By adjusting the ratio of distance from film to lens to ...

Continuously varied JPEG compression (between Q=100 and Q=1) for an abdominal CT scan. JPEG (/ ˈ dʒ eɪ p ɛ ɡ / JAY-peg, short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) [2] [3] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
How Effective is Sildenafil 100mg? Sildenafil works well for most men with ED at any dosage, although the highest 100mg dosage produces improvements for a greater percentage of men than 50mg or 25mg.
