Optical Instruments and Imaging: The Use of Optics by 15th Century Master Painters
Invited paper for the Proceedings of Photonics Asia 2004 (SPIE, 2004) [This paper describes relevant aspects of the technology of appropriate refractive and reflective optics, complementing the optical evidence in our other papers].
Quantitative Analysis of Qualitative Images
Invited paper for the Proceedings of the IS&T/SPIE 17th Annual ‘Symposium on Electronic Imaging’ (SPIE, 2005).
Novel Expert-Based Approach to Image Analysis
Invited paper for the Proceedings of the ‘9th International Symposium on Signal Processing and its Applications’ (IEEE, 2007).
Computer Vision and Art
IEEE MultiMedia (IEEE, 2007) [This was written at the invitation of one of the editors, to address errors in three papers by someone named David Stork that they had published. Because of a strict page limitation, there wasn’t room to discuss all of the errors in Stork’s three papers.].
Ibn al-Haytham and the Origins of Computerized Image Analysis
Invited paper for the Proceedings of the 2007 ‘International Conference on Computer Engineering & Systems’ (IEEE, 2007).
The Use of Optics by Renaissance Artists
This article on ‘The Use of Optics by Renaissance Artists’, solicited by the publisher’s Scientific Board, describes how we were able to demonstrate that artists began using optical projections early in the Renaissance (McGraw-Hill, 2008).
Ibn al-Haytham’s Contributions to Optics, Art, and Visual Literacy
Invited paper for the 2008 ‘Painted Optics Symposium: Re-Examining the Hockney-Falco Thesis 7 Years On’ (Fondazione Giorgio Ronchi, 2009).

Invited paper describing a high resolution infrared camera I developed and applied to the study of several works of art, including Lorenzo Lotto’s ‘Family Portrait.’ As Fig. 7 shows, the infrared reflectogram confirms the central octagonal pattern of this painting is based on a projection that was refocused twice due to exceeding the depth-of-field of the lens or concave mirror. This, and other details of this painting revealed in the infrared (to be published elsewhere), confirms our previous analysis of how optical projections were used in the creation of significant features within this work.
