Computer graphics

FAST-0E7Acad. year: 2020/2021

Subject of computer graphics, image digitalizing (sampling, quantization), colour theory, CIE diagram, colour models, colour dispersing. Saving pixels in files (direct, non direct – range), saving images in sample lines, straps, tiles. Data compression- basic terms, theory, information, lossless methods (pixel concentration, flow compression-RLE, dictionary methods-LWZ, Huffman and arithmetic code). Loss compress methods (discrete cosine transformation, vector quantization, fractal compression, colour reaction). Vector format principals, data conversion from bitmap to vector shape and back.
The most common graphics formats. Principles of visual display unit (monitors, LCD displays), graphic adapters, printers principles. Scanner function principle and CCD cameras. Multimedia, MPEG format. 3D graphic basis.
