Our proposal is built on top of Kvazaar HEVC encoder by extending its functionality with spatial and signal-to-noise ratio (SNR) scalable coding schemes. These two scalability schemes have been optimized for real-time coding by means of three parallelization techniques: 1) wavefront parallel processing (WPP); 2) overlapped wavefront (OWF); and 3) AVX2-optimized upsampling. On an 8-core Xeon W-2145 processor, the proposed spatially scalable Kvazaar can encode twolayer 1080p video above 50 fps with scaling ratios of l.5 and 2. The respective coding gain s are 18.4% and 9.9% over Kvazaar simulcast coding at similar speed. Correspondingly, the coding speed of SNR scalable Kvazaar exceeds 30 fps with two-layer 1080p video. On average, it obtain s1.20 times speedup and 17.0% better coding efficiency over the simulcast case. These results justify the benefits of the proposed scalability schemes in real-time SHVC coding.","PeriodicalId":405734,"journal":{"name":"2020 IEEE International Conference on Image Processing (ICIP)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126323166","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}

The performance of few-shot learning is greatly affected by the number of samples per class. The massive unlabeled data can help to boost the performance of few shot learning models. In this paper, we propose a novel progressive point to set metric learning (PPSML) model for semisupervised few-shot classification. The distance metric is defined for an image of the query set to a class of the support set by point to set distance. A self-training strategy is designed to select the samples locally or globally with high confidence and use these samples to progressively update the point to set distance. Experiments on benchmark datasets show that our proposed PPSML significantly improves the accuracy of few shot classification and outperforms the state-of-the-art semisupervised few-shot learning methods.","PeriodicalId":405734,"journal":{"name":"2020 IEEE International Conference on Image Processing (ICIP)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121593028","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}

It currently achieves 31% BDRATE gains over VP9, and is on its way to becoming YouTube’s default codec. Although the industry is currently focused on the implementation and optimization of AV1, AOMedia Research continues to develop new coding tools that deliver higher coding gains within acceptable complexity bounds. Here, we focus on improving transform coding. While AV1 has made great strides in transform coding over VP9, the residue signal still consumes a large portion of the bitstream. In this paper, we describe a more flexible transform partitioning scheme, which will allow the next generation codec to more efficiently target areas in the residue signal with high energy, leading to better residue compression.","PeriodicalId":405734,"journal":{"name":"2020 IEEE International Conference on Image Processing (ICIP)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132132419","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, these techniques experience performance degradation when the compression ratio is increased to an extreme extent. In this paper, we propose Cascaded Mixed-precision Networks (CMNs), which are compact yet efficient neural networks without incurring performance drop. CMN is designed as a cascade framework by concatenating a group of neural networks with sequentially increased bitwidth. The execution flow of CMN is conditional on the difficulty of input samples, i.e., easy examples will be correctly classified by going through extremely low-bitwidth networks, and hard examples will be handled by high-bitwidth networks, so that the average compute is reduced. In addition, weight pruning is incorporated into the cascaded framework and jointly optimized with the mixed-precision quantization. To validate this method, we implemented a 2-stage CMN consisting of a binary neural network and a multi-bit (e.g. 8 bits) neural network. Empirical results on CIFAR-100 and ImageNet demonstrate that CMN performs better than state-of-the-art methods, in terms of accuracy and compute.","PeriodicalId":405734,"journal":{"name":"2020 IEEE International Conference on Image Processing (ICIP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130206511","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}

In this paper, we propose a new gradient deconfliction-based training technique for multi-exit architectures. In particular, the conflicting between the gradients back-propagated from different classifiers is removed by projecting the gradient from one classifier onto the normal plane of the gradient from the other classifier. Experiments on CFAR-100 and ImageNet show that the gradient deconfliction-based training strategy significantly improves the performance of the state-of-the-art multi-exit neural networks.

Events recorded by sensors have a lot of noise and the intensity images captured often suffer from motion blur and noise effects. Therefore, to reconstruct high quality images is of great significance for the application of event camera in computer vision. However, the existing reconstruction methods only addressed the motion blur issue without considering the influence of noise. In this paper, we propose a variational model by using spatial smooth constraint regularization to recover clean image frames from blurry and noisy camera images and events at any frame rate. We present experimental results on synthetic dataset as well as real dataset with high speed and high dynamic range to demonstrate that the proposed algorithm is superior to the other reconstruction algorithms.","PeriodicalId":405734,"journal":{"name":"2020 IEEE International Conference on Image Processing (ICIP)","volume":"21 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131084830","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}

X-Net takes advantage of Long Skip Connections and Cross Branch Connections to generate raindrop-free image with enough details. RAD-Net assists X-Net to produce better results by yielding raindrop location.
