Error control for scalable image and video coding
Scalable image and video has been proposed to transmit image and video signals over lossy networks, such as the Internet and wireless networks. However, scalability alone is not a complete solution since there is a conflict between the unequal importance of the scalable bit stream and the agnostic …

Optimal Linear Processing for Image and Video Coding
… modulation (DPCM) loop employed in the coding of video sequences is inefficient at low bit rates. Using a Gaussian auto-regressive model, we propose the incorporation of rate-distortion optimized filters into the DPCM loop. It is shown that these filters trade off less important spectral …

Dynamically Reconfigurable Architectures and Systems for Time-varying Image Constraints (DRASTIC) for Image and Video Compression
In the current information booming era, image and video consumption is ubiquitous. The associated image and video coding operations require significant computing resources for both small-scale computing systems as well as over larger network systems. For different scenarios, power, bitrate and …

Digital Hardware Architectures for Exact and Approximate DCT Computation Using Number Theoretic Techniques
… cosine transform (DCT) is a key tool in many image and video coding applications. Therefore significant effort is been made to realize DCT computation utilizing minimum resources in terms of hardware, at acceptable accuracy. This thesis explores the use of number theoretic techniques such as …

Reduction of blocking artifacts using side information
Block-based image and video coding systems are used extensively in practice. In low bit-rate applications, however, they suffer from annoying discontinuities, called blocking artifacts. Prior research shows that incorporating systems that reduce blocking artifacts into codecs is useful because …
