WINDOW-LEVEL RATE CONTROL FOR SMOOTH PICTURE QUALITY AND SMOOTH BUFFER OCCUPANCY
Rate Control Smooth Picture Quality ½ - domain Window Buffer Occupancy
2011/7/24
rate control consists of bit allocation and QPdecision on R-QP model. In bit allocation, target bits is further confined if buffer overflows. Meanwhile, rate controlshould also give as smo...
A Novel Rate Control Technique for Multiview Video Plus Depth Based 3D Video Coding
Multiview video coding rate control video plus depth representation 3D video coding
2011/2/24
This paper presents a novel rate control technique formultiview video plus depth (MVD) based 3D video coding. In theproposed rate control technique, an image-stitching method is firstutilized to...
Estimating the Value of theta in the Intra Frame for rho-domain Rate Control Algorithms
Intra Frame rho-domain Rate Control Algorithms
2009/12/31
The -domain rate control algorithm is very simple and effective.There is only one parameter, , used in the model. reflects the relationship between the rate and the quantization step. Accurately es...
A ROI QUALITY ADJUSTABLE RATE CONTROL SCHEME FOR LOW BITRATE VIDEO CODING
region of interest rate control SSIM
2009/5/16
This paper proposed a novel Region of Interest (ROI) based rate control algorithm for video communication systems, in which the subjective quality of ROI can be adjusted according to users’ requiremen...
Adaptive rate control for H.264
rate control H.264
2006/12/31
This paper presents a rate control scheme for H.264 by introducing the concept of basic
unit and a linear prediction model. The basic unit can be a macroblock (MB), a slice, or a
frame. The linear m...
ESTIMATING THE VALUE OF θ IN THE INTRA FRAME FOR ρ-DOMAIN RATE CONTROL ALGORITHMS
ρ-domain Rate Control θ Estimation
2006/5/16
The ρ-domain rate control algorithm is very simple and effective. There is only one parameter, θ, used in the model. θ reflects the relationship between the rate and the quantization step. Accur...
Rate-Distortion Analysis for H.264/AVC Video Coding and its Application to Rate Control
H.264/AVC hypothetical reference decoder (HRD) rate control rate-distortion optimization (RDO) video coding
2005/12/23
In this paper, an efficient rate-control scheme for H.264/AVC video encoding is proposed. The redesign of the quantization scheme in H.264/AVC results in that the relationship between the quantization...
A Study on the Quantization Scheme in H.264/AVC and Its Application to Rate Control
Quantization Scheme H.264/AVC Rate Control
2004/12/31
Compared with previous video coding standards,H.264/AVC employs a division-free quantization scheme. The relation
between quantization parameter and quantization step changes from general linear to e...
