Avinash C. Kak (born 1944) is a professor of Electrical and Computer Engineering at Purdue University who has conducted pioneering research in several areas of information processing.

[citation needed] Born in Srinagar, Kashmir, he did his Bachelors in BE at University of Madras and Phd in Indian Institute of Technology Delhi.

[1] His contributions include the 3D-POLY, which is the fastest algorithm for recognizing 3D objects in depth maps[3] In 1992, Kosaka and Kak published FINALE,[4] which is considered to be a computationally efficient and highly robust approach to vision-based navigation by indoor mobile robots.

In 2003, a group of researchers that included Kak developed a tool for content-based image retrieval that was demonstrated by clinical trials to improve the performance of radiologists.

[7] The SART algorithm[8] (Simultaneous Algebraic Reconstruction Technique) proposed by Andersen and Kak in 1984 has had a major impact in CT imaging applications where the projection data is limited.

In addition, during the last decade, Kak has collaborated with people in industry and developed metrics for measuring the quality of large software systems and the usability of APIs (Application Programming Interfaces).
