Computer-assisted pattern recognition holds much promise for important applications in clinical medicine.In many instances successful automatic pattern recognition requires an analysis of the texture of a picture by a conventional digital computer, but this procedure involves a type of computing that is presently too time-consuming and expensive for practical application.In response to this situation, we have designed and developed an auxiliary computer called TEXAC (TEXture Analysis Computer).TEXAC can perform most whole picture operations at a rapid television rate of 1/30th of a second, and display the results continuously on color and black and white video monitors.Here we present the architecture of the TEXAC, both the hardware and software systems, and discuss potential biomedical applications and several interesting whole picture operations accomplished by the new computer.
