Featured on Meta.The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

JPEG typically achieves compression with little perceptible loss in image quality. JPEG compression is used in a number of image file formats. Natarajan of Kansas State University and K.

Rao of the University of Texas in Smith and S. Fralick that described a fast DCT algorithm, [1] [15] as well as a paper by N.

Narasinha and S. Fralick, and a paper by B. Pratt as an influence on its quantization algorithm, [1] [16] and David A. Huffman 's paper for its Huffman coding algorithm. The JPEG specification cites patents from several companies. The following patents provided the basis for its arithmetic coding algorithm. Klenke in October The patent describes a DCT-based image compression algorithm, and would later be a cause of controversy in see Patent controversy below.

Founded inthe group developed the JPEG standard during the late s. Among several transform coding techniques they examined, they selected the discrete cosine transform DCTas it was by far the most efficient practical compression technique. The group published the JPEG standard in The JPEG standard specifies the codecwhich defines how an image is compressed into a stream of bytes and decompressed back into an image, but not the file format used to contain that stream.

InForgent Networks asserted that it owned and would enforce patent rights on the JPEG technology, arising from a patent that had been filed on October 27,and granted on October 6, U. This led to Forgent acquiring ownership over the patent. The JPEG committee investigated the patent claims in and were of the opinion that they were invalidated by prior art[29] a view shared by various experts.

Natarajan and K. Pratt for its quantization algorithm. In AprilForgent sued 31 other companies to enforce further license payments. In July of the same year, a consortium of 21 large computer companies filed a countersuit, with the goal of invalidating the patent. In addition, Microsoft launched a separate lawsuit against Forgent in April This makes any appeal to reinstate the patent highly unlikely to succeed. Forgent also possesses a similar patent granted by the European Patent Office inthough it is unclear how enforceable it is.

Convert PNG to BaseBasically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation.

Base64 encoding schemes are generally used when there is a need to encode binary information that needs to be stored and transferred over media that are developed to deal with textual information. This guarantees that the data stays unchanged without modification during transfer. The specific set of characters chosen for the 64 characters needed for the base can vary among implementations.

The common concept is to select a set of 64 characters that is both part of a subset typical to most encodings. This mixture leaves the data impossible to be altered in transportation thru information systems, such as electronic mail, that were typically not 8-bit clean. Other Base64 variations share the same property but they use different symbols in the last two values.
