Poorvi L. Vora - Research in Color Image Processing
Many of my research results influence the design and calibration of image capture devices, such as scanners and digital cameras.

The first measure of a set of color filters (as opposed to individual color filters), which later came to be known as the Vora value. was proposed in [5,12,13], and was applied to filter design in [4,11]. A sensitivity analysis of the measure was performed in [3] and [3,4] used to fabricate filters in [11]. A digital camera simulator and procedures for calibrating color cameras were described in [2,8,9,14,15]. The importance of orthogonality in color recording filters was described in [1], and [8] used the results of [1] to explain why second generation digital cameras that used CMYG (complementary) filters produced far worse image quality than first generation cameras which used RGB (primary) filters. Orthogonality was one of the criteria used to compare filters in [6].

The work on measure, design and sensitivity formed my doctoral dissertation [17], was partially supported by Eastman Kodak, and was performed in collaboration with my adviser, H. Joel Trussell. The experimental work applying these ideas was done in collaboration with Larry Iwan. The work on digital camera simulation was performed at Hewlett-Packard Labs., in close collaboration with David H. Brainard (then of UCSB, now at Penn) and my then manager, Joyce E. Farrell. The work on orthogonality was single-author work, while applications involved collaborations with Cormac Herley, Richard L. Baer, William D. Holland and Jack Holm.
