Biography
Mestha, Lalit K.; Dianat, Sohail A.
"... brings together the technical fields of imaging systems and feedback control systems in a self-contained manner. ... an excellent addition to the literature on the analysis and design of color-imaging systems. It should be recommended to anyone who wants to become familiar with state-of-the-art techniques in these areas."
-- Daniel Viassolo, Vestas Technology R&D, Power Plant Department, Houston, Texas
