Two Decades of Colorization and Decolorization for Images and Videos [article]

Shiguang Liu
2022 arXiv   pre-print
Different from image decolorization, video decolorization should not only consider the image contrast preservation in each video frame, but also respect the temporal and spatial consistency between video  ...  On the contrary, decolorization is to convert a color image or video into a grayscale one.  ...  [79] proposed a real-time video decolorization method using bilateral filtering.  ...

OR-PCA with MRF for Robust Foreground Detection in Highly Dynamic Backgrounds [chapter]

Sajid Javed, Seon Ho Oh, Andrews Sobral, Thierry Bouwmans, Soon Ki Jung
2015 Lecture Notes in Computer Science  
But RPCA presents the limitations of computational complexity and memory storage due to batch optimization methods, as a result it is difficult to apply for real-time system.  ...  OR-PCA with good initialization scheme using image decomposition approach improves the accuracy of foreground detection and the computation time as well.  ...  Since traditional RPCA via PCP based algorithms, either gets fail to load large amount of input video frames or take longer time for optimization which is not useful for real time processing.  ...
