Image compression minimizes the file size (in bytes) of an image. Two of the most common compressed image formats are JPEG and GIF. See also MPEG and Motion JPEG.
the compression of graphics for storage or transmission
These are techniques which are used to reduce the size of digital image files. Lossless compression techniques, such as those used in the GIF and TIFF formats, retain all of the original image data while still reducing the overall file size. Lossy compression techniques, such as those used in the JPG format, compress the image file by removing image details (usually those details that the eye does not see very well) and thus losing some of the original data.
a method to reduce the amount of data needed to reproduce an image. Lossless image compression means there is no loss of original digital image information upon reconstruction. Lossey compression means that there is some permanent loss of digital image data.
Compresses higher resolution images into lower, for example compressing a SVGA (800 x 600) down to VGA (640 x 480).
File size reduction. Lossless compression enables images to be decompressed without degradation in image quality. Lossy compression sacrifices varying degrees of image detail for greater compression ratios – usually used in Multimedia applications.
Image Compression is a technology that uses a mathematical algorithm to make the image file sizes smaller. This increases the number of images that can be stored on your computer. The image files move around and open faster. There are two types of compression algorithms that are commonly used today. They are known as "Lossy" and "Lossless" compressed files. Most of today's digital cameras can create the "lossy" type. The lossy images that are created inside your digital camera automatically removes and changes an undetermined amount of image color, image sharpness and image quality to make it smaller. Valuable image data is lost when making "lossy" compressed images. The amount of image compression can be set to high, medium or low on most digital cameras. (An original JPG/JEPG is an example of a "lossy" compressed image.)"Lossless" compressed files are compressed with no loss of image color, image sharpness and image quality. The files sizes are smaller than an uncompressed image, but larger than a lossy compressed file. "Lossless" compressed files are as good as uncompressed TIFF and RAW files. (A JPG2000 is an example of a "lossless" compressed image.)
In order to store digital pictures, data is compressed. However, compression often causes a reduction in picture quality.
Image compression is the application of data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.
