In this study, we proposed a systematic procedure based on high order Zernike transform to align the images of one subject at different scan times. To estimate the rotation angle between the aligned images, we extract the keypoints and their corresponding features from the images based on Scale-Invariant Feature Transform (SIFT) to. Then, the matching white matter hyperintensities in the pre and post stages is performed after all the post images are rotated and translated to the coordinates of the first scan image.","PeriodicalId":383401,"journal":{"name":"Proceedings of the 2020 4th International Conference on Digital Signal Processing","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126808310","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}

Adaptive algorithms are often used to solve the problem. The weights of the filter in the algorithms are updated according to the minimum mean square error when it works. This method cannot effectively eliminate the nonlinear components of the self-interference signal in some special cases. In order to solve this problem, a method of self - interference cancellation based on deep neural networks is proposed in this paper. The networks simulate the behavior model of the nonlinear amplifier through training. And then it reconstructs the nonlinear components of the self-interference signal, so that this part can be effectively eliminated.","PeriodicalId":383401,"journal":{"name":"Proceedings of the 2020 4th International Conference on Digital Signal Processing","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127509650","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 a parallel prefix adder depends on the depth of logic gates and the numbers of prefix nodes for the prefix network. In this paper, a 16-bit parallel prefix adder with new prefix network for high speed and low area is proposed. A more compact data structure is applied to reduce the size of the prefix network. Hybrid radix-2 and radix-3 prefix nodes are used to reduce logic depth on the critical path of the adder, and cloning nodes are used to avoid large fan-out. Synthesis results demonstrate that this new adder is better than industry standard Synopsys Design Compiler (DC) adder, regular adders such as Kogge--Stone and Brent-Kung adders in TSMC 28 nm technology. The 16-bit new adder is 1.14 ps faster in delay and 12.216 um2 smaller in area than Synopsys DC adder.","PeriodicalId":383401,"journal":{"name":"Proceedings of the 2020 4th International Conference on Digital Signal Processing","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133893510","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 proposed model is made of the weight oversampling algorithm in data processing, and the proportional voting random forest in recognition algorithm.

Our proposed model is provided with the ability to extract multi-scale features with fewer parameters by designing MSDC (multi-scale dilation convolution) blocks. The evaluation is performed on the MIT-BIH Atrial Fibrillation Database, and our multi-dilation CNN composed of MSDC blocks outperforms other methods with a sensitivity of 99.45% and specificity of 99.61%.

And the performance of AVS3 base profile is improved by 20% compared to the H.265. This paper proposes improvements to the deblocking scheme of AVS3, which has been adopted in the AVS3 baseline profile. The deblocking scheme in AVS2 has defects, including unreasonable filtering conditions and filtering coefficients. The deblocking filter in AVS3 also has the same drawback because it inherits the deblocking scheme from AVS2. These defects lead to unsatisfactory subjective quality of the AVS3 deblocking filter. Hence this paper improves the subjective quality of the AVS3 deblocking filter by reasonably modifying the filtering conditions and filter operation. In addition, to reduce the complexity of deblocking filter in AVS3, the proposed method simplifies the filtering operation of chroma deblocking. We implement the method on top of the AVS3 reference software (HPM-2.1), and the experimental result shows that subjective quality is significantly improved. The proposed method achieves 0.28% BD-rate reduction under Random Access (RA) configuration and 0.21% BD-rate reduction under ALL INTRA (AI) configuration.","PeriodicalId":383401,"journal":{"name":"Proceedings of the 2020 4th International Conference on Digital Signal Processing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127248078","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}
