In this paper, we present a method for performing rate-distortion optimization (RDO) using a perceptual visual quality metric, the structural similarity index (SSIM), as the target of optimization. Rate-distortion optimization is widely used in moder

We present a method for analyzing dynamic range along the residual coding and reconstruction pathways during video coding by deriving bounds on the maximum absolute value of intermediary data using a simple combination of triangle inequality and refo

Intra prediction improves coding performance by reducing inter pixel redundancy. However, to accommodate the use of block transforms, not all pixels can be predicted from reconstructed pixels that are located close to themselves. This causes predicti

One of the challenges in video rate control lies in determining a quantization parameter (Qp) that will be used for both the rate-distortion (R-D) optimization process and the quantization of transform coefficients. In this paper, we attempt to achie

The use of mode-dependent transforms for coding directional intra prediction residuals has been previously shown to provide coding gains, but the transform matrices have to be derived from training. In this paper, we derive a set of separable mode-de

The H.264/AVC video coding standard encapsulates the most advanced video coding tools. Since the various techniques that lead to better coding efficiency of the coding standard also inevitably increase the complexity of the video encoder, real-time H

In this paper, we introduce a low-complexity fine-granularity scalable (FGS) video encoder that refines both residue and motion information in the quality layers. The current scalable video coding (SVC) draft shows that significant gains can be achie

To achieve a target bit-rate reduction of 50% over H.264/AVC while maintaining equivalent perceptual video quality, High Efficiency Video Coding (HEVC) includes several new coding tools including a new set of integer transforms. Since these transform

Image quality metrics (IQMs), such as the mean squared error (MSE) and the structural similarity index (SSIM), are quantitative measures to approximate perceived visual quality. In this paper, through analyzing the relationship between the MSE and th

Seam carving, an image re-targeting method, works by progressively finding and removing connected paths of low energy pixels in an image until a desired image aspect ratio is reached. In this paper, we first cast the problem of minimizing an energy f
