A fully automatic approach to facial feature detection and tracking
1997The detection of facial features is a necessary step for a wide range of applications e.g. person verification, lipreading and model-based face coding. Due to changes in illumination, visual angle and facial expressions, the variability of facial features in their appearance is high.

Robust Dissolve Detection Using Local Feature Tracking
2007 IEEE Workshop on Applications of Computer Vision (WAC V '07), 2007In this paper we propose a novel dissolve detection algorithm which overcomes the defects of previously suggested algorithms. Differentiating dissolve from the effect aroused by camera motion or objects movement has long been a problem irritating the researchers and not settled thoroughly yet.

Event-driven Feature Detection and Tracking for Visual SLAM
2022Traditional frame-based cameras have become the de facto sensor of choice for a multitude of applications employing Computer Vision due to their compactness, low cost, ubiquity, and ability to provide information-rich exteroceptive measurements. Despite their dominance in the field, these sensors exhibit limitations in common, real-world scenarios ...

Face tracking and facial feature detection with a webcam
3rd European Conference on Visual Media Production (CVMP 2006). Part of the 2nd Multimedia Conference 2006, 2006We first present a multiple faces tracking algorithm using color. The skin color distribution is evaluated over the face candidate resulting from Viola&Jones face detector. This face detector is robust in case of an up-right face, but fails to detect slanted faces (pan and tilt pose): location and size of face are tracked using the skin color ...

Vehicle Detection and Tracking Based on Color Feature
2017 International Conference on Recent Advances in Electronics and Communication Technology (ICRAECT), 2017Determining the vehicle density running on the specific road is an important topic in Intelligent Transportation System. Reliable and robust vehicle detection from video sequence is an important problem in the application to control the traffic. The processing time of the vehicle detection system should meet the real time and should be free from false ...

Lip contours detection and tracking with multi features
2008 Biometrics Symposium, 2008Lip contours detection and tracking has been studied extensively because it can significantly improve the performance of the automatic speech recognition and face recognition systems. A major challenge is to find a robust and accurate method for detecting and tracking lip contours.
