Colorizing Black and White Videos with Damping Factor and Pixel Tolerance: Reducing Flickering Effect

Colored videos are more attractive to audiences compared to black and white videos. This can be seen through recent adaptions of old black and white movies into their colored versions. Given the relevance in the industry, this project tackles the problem of colorizing videos effectively. Previous attempts on the same topic could not do this efficiently as they always encountered the vital issue of a “flickering effect.” The said flickering effect is observed when the frames are colored individually and then reassembled to form a video. To solve this issue, we introduce two parameters, namely, a damping factor and a pixel tolerance. We have also fine-tuned the parameters for the most optimal result through experimentation. Finally, using custom metrics, we showcase the efficiency and effectiveness of this method.
