User-assisted Video Reflection Removal [article]

Amgad Ahmed, Suhong Kim, Mohamed Elgharib, Mohamed Hefeeda
2020 arXiv   pre-print
To address this problem, we propose a user-assisted method for video reflection removal. We rely on both spatial and temporal information and utilize sparse user hints to help improve separation.  ...  A video containing reflections is a combination of background and reflection layers. Thus, reflection removal is equivalent to decomposing the video into two layers.  ...  CONCLUSION We have presented a user-assisted method to remove undesired reflections from videos.  ...

User-assisted reflection detection and feature point tracking

Mohamed A. Elgharib, François Pitite, Anil Kokaram, Venkatesh Saligrama
2013 Proceedings of the 10th European Conference on Visual Media Production - CVMP '13  
User feedback is common in post-production video manipulation tools. Hence in the second contribution we propose an effective way of integrating few user-assisted masks to improve detection rates.  ...  As a result reflections cause many techniques to fail e.g. detection, tracking, motion estimation, etc. Recent work was proposed by Ahmed et al. [5] to detect reflections.  ...  USER ASSISTANCE FOR ROBUST DE-TECTION Missed detections could occur if the reflections contain weak feature points (see Fig. 2 , red).  ...

Fast Shadow Removal Using Adaptive Multi-Scale Illumination Transfer

Chunxia Xiao, Ruiyun She, Donglin Xiao, Kwan-Liu Ma
2013 Computer graphics forum (Print)  
In this paper, we present a new method for removing shadows from images. First, shadows are detected by interactive brushing assisted with a Gaussian Mixture Model.  ...  Second, the detected shadows are removed using an adaptive illumination transfer approach that accounts for the reflectance variation of the image texture.  ...  This technique applies only minimal user assistance and achieves satisfactory shadow detection results.  ...
