Abstract

Video compression algorithms are pervasively applied at the camera level prior to video transmission due to bandwidth constraints, thereby reducing the quality of video available for video analytics. These artifacts may lead to decreased performance of some core applications in video surveillance systems such as object detection. To remove such distortions during video decoding, it is required to recover original video frames from distorted ones. To this end, we present a fully convolutional residual network for compression artifact removal (CAR-CNN) without prior knowledge on the noise distribution trained using a novel, differentiable loss function. To provide a baseline, we also trained our model by optimizing the Structural Similarity (SSIM) and Mean Squared Error (MSE). We test CAR-CNN on self-collected data, and we show that it can be applied as a pre-processing step for the object detection task in practical, non-idealized applications where quality distortions may be present.
