A new color space, YCgCr, is described and applied for face detection. Although similar to
the YCbCr color space, it differs in the use of the Cg color component instead of the Cb one …

The disclosure is directed to techniques for region-of-interest (ROI) video processing based
on low-complexity automatic ROI detection within video frames of video sequences. The low …

We present a method for extracting local visual perceptual cues and its application for rate
control of videophone, in order to ensure the scarce bits to be assigned for maximum …

It is very challenging to recognize a face from an image due to the wide variety of face and
the uncertain of face position. The research on detecting human faces in color image and in …

In order to detect more reliably skin color for color facial image with complicated
background, we have presented a detection method based on uniting YCgCb color space …

This paper describes a modified rate control algorithm for H. 264 that can accommodate
multiple priority levels given a region of interest (Rol). The modified method allows better …

Developments in our ability to integrate and analyse the data held in existing heterogeneous
data resources can lead to an increase in our understanding of biological function at all …

This article discusses a framework for model-based, context-dependent video coding based
on exploitation of characteristics of the human visual system. The system utilizes variable …
