U-net: Convolutional networks for biomedical image segmentation. As the first work of learning-based video compression, we compare our scheme with two representative HVC codecs: MPEG-2 (v1.2) [45] and H.264 (JM 19.0) [46] in our experiments. Video compression techniques and tools aim to reduce the size of a video by eliminating redundancies. Video codecs should not be confused with video formats. Also, we implement this scheme in a simplest way in this paper, similar to skip mode defined in traditional video coding framework [39]. frames and their optical flow leads to a 300x300,8 dataset which is memory A tag already exists with the provided branch name. Recently there are two kinds of research work trying to apply machine learning techniques into image/video compression problem, one is Codec-based improvements which introduces learning-based optimization modules combined with traditional image/video codecs, another is pure Learning-based compression framework which are mainly focused on learning-based image compression schemes in current stage. During the training phase, PMCNN, iterative analyzer / synthesizer and binarizer are jointly optimized to learn a compact representation of input video sequence. Figure 6 demonstrates efficiency of the proposed PMCNN framework, the one simultaneously conditioned on spatial and temporal dependencies (PMCNN) outperforms the other two patterns that conditioned on individual dependency (Temporal-Pred and Spatial-Pred) or none of these dependencies (No-Pred). This term describes many statistical algorithms which can 'learn' by detecting patterns in data. Conventional video coding methods optimize each part separately which might lead to sub-optimal solution. Unfortunately, lossless compression does not allow for drastically reducing the file size. So there exist strong requirements to explore new video coding directions and frameworks as potential candidates for future video coding schemes, especially considering the outstanding development of machine learning technologies. Given a target bitrate, QPs for video frames are decided sequentially to maximize overall video quality. pp For example, Convolutional Neural Networks are used to improve video compression, especially for video streaming. Many approaches [40, 21, 11, 19, 20] were proposed to re- www.itu.int/rec/T-REC-H.264. Each column represents the PSNR/MS-SSIM performance on test sequence. We calculate the time consuming of our scheme and traditional codecs on the same machine (CPU: i7-4790K, GPU: NVIDIA GTX 1080). And now it encountered great challenges to further significantly improve the coding efficiency and to deal efficiently with novel sophisticated and intelligent media applications such as face/body recognition, object tracking, image retrieval, etc. M.Covell, and R.Sukthankar, Variable rate image compression with Each image is down-sampled to 256x256 to enhance the texture complexity. The residuals between reconstruction and target are analyzed and synthesized iteratively to provide a variable-rate compression. Specifically, we construct a neural network to predict each block of video sequence conditioned on previously reconstructed frame as well as the reconstructed blocks above and to the left of current block. As the first work of learning-based video compression, we quantitatively analyze the performance of our framework and compare it with modern video codecs. Our bitstream mainly consists of two parts: the quantized representation generated from iterative analysis / synthesis and flags that indicates the selected mode for temporally progressive coding (<1% bitstream). For instance, a neural network-based object tracking algorithm can be employed as a semantic metric for surveillance video compression. A human is supervising the learning process. [7], we add a probabilistic quantization noise for the forward pass and keep the gradients unchanged for the backward pass: where cin[1,1] represents the input of binarizer. The video coding performance improves around 50%. (IP) to solve customer design challenges in the areas of intelligent video and vision processing. Another similar method is to directly compress the network parameters. This category only includes cookies that ensures basic functionalities and security features of the website. The receiver device then reconstructs the video with a generator and a keypoint detector, by transforming and animating the keypoints of the source image according to the video keypoints.

Our scheme for video compression can be divided into three components: predictive coding, iterative analysis/synthesis and binarization. The results are Scopus and Web of Science are well-known research databases. The output of binarizer can thus be formulated as cout=cin+. Neural Exploration via Resolution-Adaptive Learning, Generalized Difference Coder: A Novel Conditional Autoencoder Structure Although affected by the above factors and our learning-based video compression framework is in its infancy stage to compete with latest H.265/HEVC video coding technologies[12], it still shows great improvement over the first successful video codec MPEG-2 and has enormous potential in the following aspects: We provide a possible new direction to solve the limitation of heuristics in HVC by learning the parameters of encoder/decoder. It does so by working out patterns and rules, for example, 'if a block contains lots of detail, consider splitting it up into smaller blocks for encoding'. DerSmagt, D.Cremers, and T.Brox, Flownet: Learning optical flow with IEEE Journal of . International Conference on Intelligent Technologies for Interactive Entertainment, INTETAIN 2021: Intelligent Technologies for Interactive Entertainment For example, the first work of learning-based image compression [7, 4] was introduced in 2016 and demonstrates their better performance compared with the first image coding standard JPEG. There are already codecs, such as JPEG and PNG, whose aim is to reduce image sizes. [ 22] proposed the Deep Video Compression (DVC) method, in which the optical flow is used to estimate the temporal motion, and two auto-encoders are employed to compress the motion and residual, respectively. The black dashed arrow in (b) has the same value as the black arrow, which direct where should the values in.
