These are analog sources in uncompressed .Bidirectional video compression leverages information from both past and future frames to assist in compressing video frames. In this paper, we propose a novel multi-scale bidirectional context-aware adaptive contextual video compression framework. . the intra-period set to 32 and GOP size set to 16 for all the test sequences. To facilitate a . This paper proposes a deep video compression method to simultaneously encode multiple frames with Frame-Conv3D and. Deep learning (DL) methods have revolutionized the paradigm of computer vision tasks and DL-based video compression is becoming a hot topic. . UVG and HEVC Standard Test Sequences . Our video codec .satile Video Coding (VVC) host codecs: VTM 16.2 and the Fraunhofer Versatile Video Encoder (VVenC 1.4.0). The proposed approach was evaluated under the JVET HDR Common Test Conditions using the Random Access configuration. The results show coding gains over both the original VVC VTM 16.2 and VVenC 1.4.0 (w/o EBDA) on JVET HDR tested sequences,

VVC Test Model (VTM) 4.0.1 and on AV1 libaom 1.0.0, with . deep video compression. All these sequences have the same frame rate of 60 frames per second, YCbCr 4:2:0 format, and with four different spatial resolutions including 3840 2160, 1920 1080, 960 540, and 480 270. We have encoded these 9.5.1.3 Test Sequences. The four video sequences described in Table 9.11 were used in the subjective experiments. The YCbCr 4:2:0 8-bit 4K video sequences have a variety of characteristics typical of what might be encountered in the context of a streaming application, and they were selected from those that are generally available and used for .
For video content, HEVC stood out significantly, achieving compression ratios as high as 50:1 on 4K video content, far surpassing older video compression standards like H.264 [31]. In terms of quality metrics, JPEG averaged a PSNR of 30 dB and an SSIM of 0.85, indicating decent quality retention suitable for non-critical applications.

Video Compression for Screen Recorded Sequences Following
We evaluate our approach for the low-delay scenario with High-Efficiency Video Coding (H.265/HEVC), H.264/AVC and another learned video compression method, following the common test settings. Our work offers the state-of-the-art performance, with consistent gains across all popular test sequences.Lossless compression of video sequences . Implementation results on standard test sequences indicate that signi cant improvements can be obtained by the proposed techniques. 1 Introduction Most lossless image compression techniques reported in literature have been for two-tone facsimile or gray scale still images (for a survey and classi . Perceptual video coding has recently been recognized as a promising approach to achieving high-performance video compression and eye tracking data can be used to create and verify these models. . The results of encoding several test sequences and showing them to several viewers indicate that the proposed system obtains a bit rate reduction of .
Sequences of digital video images typically require vast amounts of electronic memory for storage, and occupy much bandwidth during transmission. Widely used image and video compression standards, such as JPEG and MPEG, use the two-dimensional discrete cosine transform (DCT) to achieve near-optimal compression of individual frames. This is done by .
[5]: Additionally, we include the results from testing software of traditional codecs H.265 [3] and H.266 [5] under the low-delay P (LDP) configuration for comparison in Figure 8 and Table III.Abstract: Test data compression allows compressed tests to be stored on a tester and decompressed on-chip. Test data compression has not been applied before to transparent-scan sequences in spite of their ability to provide test compaction . As the stacking sequences were asymmetrical, flipped and non-flipped stacking sequence were investigated by means of ANSYS Workbench software. Hoop compression test performance were analyzed according to ASTM D2412-11 standard test method.
Video Coding (HEVC). The study employs a diverse set of test sequences, covering bothHigh Definition (HD)andUltra High Definition (UHD)resolutions, and spans a wide range of bit-rates. . video compression standards has become a critical concern [8]. Prior research has delved into the complexity aspects of HEVCencoding/decoding for various .
Video Compression • Video: Sequence of frames (images) that are related – Related along the temporal dimension • Main addition over image compression – Temporal redundancy – Usually high frame rate: Significant temporal redundancy → Video coder must exploit the temporal redundancy.

The sequences were encoded at 5 different constant bitrates in two widely video compression standards H.264/AVC and H.265/HEVC at Full HD and Ultra HD resolutions, which means 160 annotated video sequences were created. . All these test video sequences (SRCs) were afterwards encoded to both compression standards to be evaluated, i.e., H.264 . The High Efficiency Video Coding (HEVC) standard (ITU-T H.265 and ISO/IEC 23008-2) has been developed with the main goal of providing significantly improved video compression compared with its predecessors. In order to evaluate this goal, verification tests were conducted by the Joint Collaborative Team on Video Coding of ITU-T SG 16 WP 3 and .The open Ultra Video Group (UVG) dataset is composed of 16 versatile 4K (3840×2160) test video sequences captured at 50/120 fps. All sequences are available under a non-commercial Creative Commons BY-NC license. Please cite the following paper for any usage of the dataset: A. Mercat, M. Viitanen, and . Our framework is also extensible, in which the condition can be flexibly designed. Experiments show that our method can significantly outperform the previous state-of-the-art (SOTA) deep video compression methods. When compared with x265 using veryslow preset, we can achieve 26.0% bitrate saving for 1080P standard test videos.
