Streaming Video with Optimized Reconstruction-Based DCT
One fundamental problem with streaming video data over unreliable IP networks is that packets may be dropped or arrive too late for real-time playback. Traditional error-control s...

No-Reference Quality Assessment of H.264/AVC Encoded Video
Abstract--This paper proposes a no-reference quality assessment metric for digital video subject to H.264/AVC encoding. The proposed metric comprises two main steps: coding error e...

An Efficient Criterion for Mode Decision in H.264/AVC
In this paper, an efficient cost function for mode decision in H.264/AVC is proposed. The proposed cost function is based on integer transform coefficients, where the rate and the...

Macroblock-Level Adaptive Scan Scheme for Discrete Cosine Transform Coefficients
—Discrete Cosine Transform (DCT) has been widely used in image/video coding systems, where zigzag scan is usually employed for DCT coefficient organization. However, due to local...

Image Compression with a Geometrical Entropy Coder
In this paper we propose a geometrical entropy coder to compress images with geometry. Our proposed scheme works on quantized coefficients of the discrete wavelet transform (DWT)....
