Alan W. Paeth

Alan William Paeth (/peɪθ/ PAYTH; 11 May 1956 – 3 June 2018) was a Canadian computer scientist and author.

Life and education

Alan William Paeth was born on May 11, 1956, in Seattle, Washington. He obtained a bachelor's degree in computer science from Caltech and his PhD at the University of Waterloo in 1994.[1] His undergraduate advisor was Carver Mead. His doctoral advisor was William B. Cowan and his doctoral dissertation was on Linear Models of Reflective Colour.[1] He married Catherine Anne Person in 1983; she predeceased him in 2008.[2]

He died in Kelowna, British Columbia, on June 3, 2018.[3]

Career

He was professor of computer science at Okanagan University College in British Columbia.[4]

As a PhD student he made major research contributions to computer graphics, including algorithms for shear mapping and pre–image compression filtering; the Paeth filter implemented in the Portable Network Graphics (PNG) image format was derived from his work.

Prior to starting graduate school, he worked at Xerox PARC, where he was a member of the group headed by Lynn Conway (who initiated the VLSI chip design revolution with Paeth's former Caltech advisor Carver Mead).[5]

Selected publications

His notable books include:[6][7]

  • Graphics Gems V
  • Algorithms for fast color correction
  • The IM raster toolkit : design, implementation and use
  • Linear models of reflective colour
