Foundations of Graphic Information and Digital Image Processing

Every digital image you see on a screen is actually a complex set of data processed by a computer. Understanding how this graphic information is structured is the key to working with digital media, web design, and computer science. This course guides you through the fundamental principles of digital graphics, helping you transition from simply looking at screens to understanding exactly how pixels, vectors, color spaces, and compression algorithms work behind the scenes. What you'll learn: - Understand the core differences between raster and vector graphics. - Analyze how computers represent colors using RGB, CMYK, and modern digital color models. - Compare various image file formats, including PNG, JPEG, SVG, and modern web formats like WebP. - Calculate image file sizes and understand resolution, DPI, and compression techniques. - Apply basic image processing concepts such as scaling, cropping, and filtering through conceptual exercises. - Explore digital accessibility basics, including image contrast and descriptive metadata. The course starts with essential terminology and the physical science of how screens display images. You will then progress through structured written modules covering the mathematical representation of graphics, compression types, and practical workflows for optimizing digital assets. Designed specifically for beginners, students, and anyone curious about how digital media works, this course requires no prior technical or design experience.
