In recent years, video compression techniques have been significantly challenged by the rapidly increased demands associated with high quality and immersive content. Among various tools, post-processing can be applied on reconstructed content to mitigate visible artefacts enhance overall perceptual quality. Inspired advances in deep learning, we propose a new CNN-based approach, which has integ...

With the continuous increase of network capacities, video transmissions in medicine are becoming an effective tool for second opinion diagnosis, archiving and teaching environments. This study investigates video compression delay times and transmission impairments for different compression formats and describes the resulting picture qualities. For the evaluation endoscopic video sequences were ...

Recent advances in deep generative modeling have enabled efficient of high dimensional data distributions and opened up a new horizon for solving compression problems. Specifically, autoencoder based learned image or video solutions are emerging as strong competitors to traditional approaches. In this work, We propose network architecture, on common well studied components, operating low latenc...

Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to th...

In surveillance systems, the storage requirements for video archival are a major concern because of recording of videos continuously for long periods of time, resulting in large amounts of data. Therefore, it is essential to apply efficient compression techniques for compressing surveillance video. The techniques used for the general video compression may not be the efficient technique for the ...

This paper describes the implementation of a realtime wavelet-based video codec using a new fast, non-embedded compression scheme closely related to the SPIHT algorithm by Said and Pearlman. The implementation employs block differencing for inter-frame compression and inter-block run-length encoding for even better live video compression performance. Some implementation issues are also discussed.
