C and D grades are broken down similarly like B in the 70's and 60's percentages. Any score below 60% is F.
In recent times, we have witnessed an explosive growth of multimedia technologies.The need to store and transmit large masses of information is growing very rapidly along with increasing number of applications in diverse fields covering the spectrum of human civilization in the new millenium. Engineers and computer scientists need a fundamental understanding of data compression technologies to work with large variety of data ( text, image, video, sound and any combination of these types) types and increasingly data-intensive applications. This course will provide the fundamental theories and techniques of data compression. The students will benefit from the balanced presentation of basic theory, algorithms and implementations.
Senior standing with background on design and analysis of algorithms. Open to all graduate students. This course would be especially useful to students in image and text processing, computer vision, graphics, visualization and internet technology but that other students will also benefit from the course.
Why data compression? The bandwidth gap for multimedia data: text, true color images, binary images, video and sampled sound. Input source format.
Ad hoc compression methods. Lossles and lossy compression algorithms.The components of a data compression system. performance metrics.
Introduction to Information Theory.
Statistical compression methods: Huffman and Arithmetic entrpy coders.The JBIG standards. Dictionary based compression methods: LZ family. Universal Lossless source coding. Model based compression methods: PPM, DMC. Transform based text compression: BWT transform. Work at UCF.
Image compression methods. Mathematical preliminaries. Scalar and vector quantization. Predictive coding. DPCM. Hierarchical vector quantization.
Transform Coding: DCT(JPEG/MPEG) and wavelet transform(EZW/RMF). Subband Coding. Wavelet Compression.
Brief discussion on Video and Sonud Compression.
