In Audio and Video coding Standard-3(AVS3), skip/direct has improved more performance with more candidate modes. The candidate mode list is generated by numerous prediction directions with corresponded predicted motion vectors. However, it will result in higher computation complexities and challenges to parallel computation, especially for the hardware implementation. For resolving the problem, we propose a hardware architecture of skip/direct mode with a fast motion vector prediction (MVP) algorithm in this paper. Our architecture is designed with efficient pipeline schedules. And the fast MVP algorithm can reduce the number of MVP candidates efficiently. The fast MVP method is introduced by setting a search window, some unnecessary MVP are skipped, thereby reducing the computational complexity firstly. Then the proposed hardware architecture is given with efficient pipeline schedules in detail. The experimental results show that our architecture is able to meet the requirement of 3840x2160@60FPS with only 0.48% and 0.42% BD-Rate increase under the low delay P (LDP) and random access (RA) configurations, respectively.","PeriodicalId":314555,"journal":{"name":"International Conference on Digital Image Processing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123411919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we extract keyframes according to mutual information between adjacent frames, and then the extracted keyframes are segmented to patches to calculate low-order Tchebichef moments. Since the strong description ability of Tchebichef moment, and different order of Tchebichef moment can represent independent features with minimal information redundancy, we extract statistical features of Tchebichef moment on computed patches as spatial features. Considering the influence of distortions in spatiotemporal domain to video quality, we use the three-dimensional derivative of Gaussian filters to calculate the spatiotemporal energy responses and extract statistical features from the responses as spatiotemporal features. Finally, we combine the spatial and spatiotemporal features to predict the quality of stereoscopic videos. The proposed model is evaluated on the NAMA3DS1-COSPAD1, SVQA and Waterloo IVC phase I databases. The experimental results show that the proposed model achieved competitive performance as compared with existing SVQA models.","PeriodicalId":314555,"journal":{"name":"International Conference on Digital Image Processing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123968154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing deep learning approaches formulate problems by restoring absolute pose ratios from two consecutive frames or predicting a depth map from a single image, both of which are unsuitable problems. In order to solve this maladaptation problem and further tap the potential of neural networks in SfM, this paper proposes a new optimization model for deep motion structure recovery based on recurrent neural networks. The model consists of two architectures based on depth and posture estimation of costs, and is constantly iteratively updated alternately to improve both systems. The neural optimizer designed here tracks historical information during iterations to minimize feature metric cost update depth and camera poses. Experiments show that the optimization model of deep motion structure recovery in this paper is superior to the previous method, effectively reducing the cost of feature-metric, while refining depth and poses.","PeriodicalId":314555,"journal":{"name":"International Conference on Digital Image Processing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125872692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An improved stereo matching algorithm based on RTStereoNet is proposed. Firstly, the channel attention mechanism is introduced in the matching cost aggregation stage of RTStereoNet, so that the network can adaptively enhance the extraction of effective information and reduce the ambiguity of matching. Secondly, in the disparity refinement stage of RTStereoNet, the color image is introduced to compensate for the loss of details caused by the large-scale downsampling of the network, and a lightweight disparity refinement module is constructed to expand the receptive field of the network. In addition, based on Jetson Xavier NX edge computing module, a special edge computing platform is constructed, with the help of TensorRT inference framework, the calculation support problem of special operators is solved through CUDA programming, and achieved deployment acceleration on the platform for both models before and after the improvement. The results show that after the accelerated deployment, the inference speed of the improved model can reach 30 fps on the KITTI2015 test set, and the improved model has higher accuracy than the original model.","PeriodicalId":314555,"journal":{"name":"International Conference on Digital Image Processing","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128844782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the large compute complexity and the strong data dependency in the RDOQ calculation process limit the real-time encoding in hardware design. In this paper, a fast RDOQ algorithm is proposed, which includes the RDOQ skip algorithm and the optimized rate estimation algorithm. Firstly, by detecting the Pseudo all-zero block (PZB) in advance, some unnecessary RDOQ processes are skipped, thereby reducing the computational complexity. Secondly, by optimizing the elements used in rate estimation of the RDOQ process, the strong data dependency of the process is alleviated, which allows RDOQ to be executed in parallel.

Analysis Sparse Representation (ASR) and Synthesis Sparse Representation (SSR) has been widely used to recover degraded images. But there are always unexpected noise and details loss in the recovered images, as they take relatively less account of the images’ inherent coherence between image patches. Thus, in this paper, we propose a new haze removal method based on hybrid convolutional sparse representation, with consideration of the adjacent relationship by convolution and superposition. To integrate optical model into a convolutional sparse framework, we separate transmission map by transforming it into logarithm domain. And then a structure-based constraint on transmission map is proposed to maintain piece-wise smoothness and reduce the influence brought by pseudo depth abrupt edges. Experiment results demonstrate that the proposed method can restore fine structure of hazy images and suppress boosted noise.","PeriodicalId":314555,"journal":{"name":"International Conference on Digital Image Processing","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133529156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By adopting attention masks generated by high-level features to adjust low-level features, the Feature Fusion Module (FFM) can alleviate the background interference problem at the feature level.
