Lower attentive region detection for virtual content insertion in broadcast video

Huiying Liu, Shuqiang Jiang, Qingming Huang, Changsheng Xu
2008 2008 IEEE International Conference on Multimedia and Expo  
Virtual Content Insertion (VCI) is an emerging application of video analysis. For VCI the spatial position is very important as improper placement will make the insertion intrusive.  ...  To choose the spatial position, we propose the notation of Lower Attentive Region (LAR) and provide a generic framework of LAR detection for broadcast video.  ...  INTRODUCTION Virtual Content Insertion (VCI) is an emerging application of video analysis and has been studied for several years.  ...

Yu Huang, Qiang Hao, Heather Yu
2011 2011 18th IEEE International Conference on Image Processing  
This paper is proposing a new framework of virtual ads insertion for Augmented Reality (AR) in a specific real scene, building facades of the street view videos.  ...  For the building façade, vanishing points are fully identified to detect a rectangular planar structure.  ...  [11] selected the region above the goal mouth bar or the soccer central ellipse for placing virtual ads. It can be seen playfield can be modeled and used for foreground (players) separation.  ...

A low cost framework for real-time marker based 3-D human expression modeling

Alexander Woodward, Yuk Hin Chan, Rui Gong, Minh Nguyen, Trevor Gee, Patrice Delmas, Georgy Gimel'farb, Jorge Alberto Marquez Flores
2017 Journal of Applied Research and Technology  
This work presents a robust, and low-cost framework for real-time marker based 3-D human expression modeling using off-the-shelf stereo web-cameras and inexpensive adhesive markers applied to the face.  ...  Tracked markers are then mapped onto a 3-D face model with a virtual muscle animation system.  ...  CLM-Z failed when facial hair was encountered; eye detection was weak in most cases and mouth corner detection failed with wide smiles or unexpected shapes, a feature common to most contour based and appearance  ...
