Background
Capillary malformation (CM) is the most common vascular malformation. Large scale studies on its incidence and risk factors are limited in China.
Objective
Our study aimed to investigate the incidence of CM in Chinese infants and to evaluate its potential risk factors.
Methods
A cross‐sectional study, including 7299 infants (aged < 1 year) were collected by a self‐administered questionnaire...
Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Such degradation even becomes worse in 1Seg video broadcasting, which is widely used in Japan and Brazil for mobile phone TV service recently, where errors are drastically increased and lost areas are contiguous. Therefore the errors in earlier concealed...
Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. The error concealment (EC) is used to recover the lost data by the redundancy in videos. 1Seg is a recently widely used mobile TV service, which is one of services of ISDB-T (Integrated Services of Digital Broadcasting-terrestrial) in Japan and Brazil...
Nowadays, TV broadcasting has found its application in mobile terminal, however, due to the prediction structure of video coding standards, compressed video bitstreams are vulnerable to wireless channel disturbances for real-time transmission. In this paper, we propose a novel temporal error concealment method for mobile TV sequences. The proposed ordering methods utilizes continuity feature among...
Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Such degradation even becomes worse in 1Seg video broadcasting application, which is widely used in Japan and Brazil for mobile phone TV service, where errors are drastically increased and huge conjunctive areas inside a picture may be corrupted. In this...
Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Aimed this problem, this paper proposes an adaptive concealment order based on well know boundary matching algorithm. The concealment order is carefully chosen according to a lost MB's priority, which is formulated considering 2 factors, MV (motion vector)...
As the newest video coding standard, H.264/AVC adopts the high-efficiently predictive coding and variable length entropy coding to achieve high compression efficiency. On the other side, transmission errors become the major problem faced by video broadcasting service providers. Error concealment (EC) here is adopted to handle slices with huge conjunctive corrupted areas inside. Considering error propagation...
