Joan L. Mitchell
Joan Laverne Mitchell (May 24, 1947 – December 2, 2015) was an American computer scientist, data compression pioneer, and inventor who, as a researcher at IBM, co-invented the JPEG digital image format. Early life Mitchell was born on May 24, 1947, in Modesto, California. Mitchell's father was William Mitchell and her mother was Doris Mitchell. Education Mitchell was a National Merit Scholar at Stanford University, where her work included an independent study project on Brillouin scattering in bromine. In 1969, Mitchell graduated with a Bachelor of Science degree in physics from Stanford University with distinction and Phi Beta Kappa. She followed in the footsteps of her grandmother, Eulalia Richardson Mitchell, who also earned Stanford physics degrees in 1910 and 1912. Mitchell went on to graduate study in condensed matter physics at the University of Illinois at Urbana–Champaign, and earned a master's degree in 1971 and a Ph.D. in 1974 there. As part of her ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

JBIG
JBIG is an early lossless image compression standard from the Joint Bi-level Image Experts Group, standardized as ISO/IEC standard 11544 and as ITU-T recommendation T.82 in March 1993. It is widely implemented in fax machines. Now that the newer bi-level image compression standard JBIG2 has been released, JBIG is also known as JBIG1. JBIG was designed for compression of binary images, particularly for faxes, but can also be used on other images. In most situations JBIG offers between a 20% and 50% increase in compression efficiency over Fax Group 4 compression, and in some situations, it offers a 30-fold improvement. JBIG is based on a form of arithmetic coding developed by IBM (known as the Q-coder) that also uses a relatively minor refinement developed by Mitsubishi The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group historically descended from the Mitsubishi zaibatsu, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Modesto, California
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

IBM Fellow
An IBM Fellow is an appointed position at IBM made by IBM's CEO. Typically only four to nine (eleven in 2014) IBM Fellows are appointed each year, in May or June. Fellow is the highest honor a scientist, engineer, or programmer at IBM can achieve. Overview The IBM Fellows program was founded in 1962 by Thomas Watson Jr., as a way to promote creativity among the company's "most exceptional" technical professionals and is granted in recognition of outstanding and sustained technical achievements and leadership in engineering, programming, services, science, design and technology. The first appointments were made in 1963. The criteria for appointment are stringent and take into account only the most-significant technical achievements. In addition to a history of extraordinary accomplishments, candidates must also be considered to have the potential to make continued contributions. Francis E. Hamilton is believed to be the first IBM Fellow, appointed in 1963 for amongst other th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
