01 A Detection Model for Driver’s Unsafe States Based on Real-Time Face-Vision
The auto industry has developed fast in the last 100 years. Although it brings us convenience, more and more traffic
accidents are happening every day. There are many factors which can cause a car accident. Based on the record of a
large number of accidents, fatigue is one of the most important factors. Additionally, driver’s distraction and
conversations with passengers during driving can lead to serious results. In this paper, a real-time vision-based model
is proposed for monitoring driver’s unsafe states, including fatigue state, distraction state and talking state, etc. By
analyzing driver’s real-time face vision, a method for detecting driver’s fatigue, distraction and talking states is given.
Also, the model is its extreme high speed and very simple equipment. It can run at about 20 frames per second in
video with 640*480 resolutions on a normal computer platform.
02 A Perceptually Relevant Approach to Ringing Region Detection
An efficient approach toward a no-reference ringing metric intrinsically exists of two steps: first detecting regions in an
image where ringing might occur, and second quantifying the ringing annoyance in these regions. This paper presents
a novel approach toward the first step: the automatic detection of regions visually impaired by ringing artifacts in
compressed images. It is a no-reference approach, taking into account the specific physical structure of ringing
artifacts combined with properties of the human visual system
