	Objectives
	THE COURSE IS DIVIDED INTO TWO MODULES. THE GOAL OF THE FIRST MODULE IS TO ACQUIRE THE BASIC KNOWLEDGE ON COMPUTER SCIENCE (COMPUTER ARCHITECTURE, BINARY REPRESENTATION OF NATURAL NUMBERS AND INTEGERS NUMBER), BASIC KNOWLEDGE ON THE IMAGE REPRESENTATIONS (RASTER AND VECTOR REPRESENTATIONS). THE MODULE ALSO FORESEES THE FUNDAMENTALS OF IMAGE PROCESSING (THRESHOLDING, STRECHING CONTRAST, SMOOTING FILTERS, DERIVATIVE FILTERS, ETC.). THE SECOND MODULE WANTS TO ENLIGHTEN STUDENTS ON THE MATHEMATICS THAT UNDERLIES THE MODERN DISPLAY SYSTEMS AND THE MODELING AND REPRESENTATION SYSTEMS. THE MODULE ALSO PROVIDES NOTES ON THE MATHEMATICS OF CURVES AND SURFACES FOR ARCHITECTURAL DESIGN ON COMPUTERS, AND THE APPLICATION OF THEORY BY USING A CAD MODELER FOR CURVES AND SURFACES (THINK DESIGN). THIS PART ALSO PROVIDES SOME DETAILS ON THE RE AND RP TECHNIQUES WITH APPLICATION EXAMPLES ON COMPUTER.
