This research accentuates the digital image watermarking, which protects the image by means of hiding a watermark image in an original image to demonstrate legal ownership.This paper suggests a new method of embedding and retrieving a watermark image besides the works within the (spatial domain) of digital images in which an invisible watermark image is embedded.

A hyper-chaotic system and a Substitution S-Box for image encryption are included in this article. Substitution is built by adapting the Rijndael S-Box into one dimension to minimize converting between digital systems using the same safety key for safe communication during the encryption process. This concept of chaos-based encryption and substitution box provides comparatively enhanced results by better CPU encryption time for images colored 256x256 to 0.2485 seconds, and 512x512 to 0.3665 seconds.

A split inductor circuit and an expanded switched capacitor circuit have been combined with a modified SEPIC converter to create this topology. A high gain voltage with low value of duty ratio is the main advantage of the implemented topology. By mixing the split inductor circuit (three diodes and two inductors) and the switched capacitor circuit (two diodes and two capacitors) with the modified SEPIC converter, the output voltage gain is increased to 7.5 with a duty ratio value of 0.5. The steady state study and the principle of operation of the presented DC-DC SEPIC converter are produced in continuous conduction mode (CCM).

The noise filter is a preprocessing technique that aims to identify and delete noisy examples in the training data to improve the performance of an induced classifier. In our previous work, we proposed a novel method deletes noisy examples, located inside the borderline region, from the majority class. The method combines the advantages of thresholding with noise filtering. In that method, the identification of noise is based on classification filter approach. One of the main drawbacks of this approach is that classifiers are organized in parallel way so they cannot benefit each other through noise identification. In this paper, we evaluate our proposed method by investigating the use of ensemble filter approach to identify noisy examples. The extended method has been assessed on 14 real imbalanced datasets. The results show that our proposal is significant in identifying noise and performs better in term of AUC scores based on random forest.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123116082","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, for the colour eye images obtained under visible wavelength (VW) without collaboration among the users, the efficiency of iris recognition degrades because of noise such as eye blurring images, eye lashing, occlusion, and reflection. This work aims to use the Local Binary Pattern (LBP) to retrieve the iris’s characteristics in both NIR iris images and visible spectrum. This approach is used and evaluated on the CASIA v1and ITTD v1 databases as NIR iris image and UBIRIS v1 as a colour image.

It’s the mobile extension of the high-performance Digital Video Broadcasting Terrestrial Second Generation (DVB-T2), with the most superior transmission technologies. One of the main modifications introduced by DVB-NGH is the advanced module of Bit-interleaved coded and modulation (BICM) based on a subset of DVB-T2 BICM elements. The diversity benefit gained by the modern features included in the DVB-NGH BICM module is examined in this study. This module incorporates two kinds of rotation schemes according to the specified coding rate: two-dimensional and four-dimensional rotated constellations (2D, 4D-RC). A comparison has been made between the acquired gain and the case of using the T2-Lite system’s fundamental BICM module, including the rotated constellations method. To confirm the efficiency of the created module, simulation results were done in MATLAB version R2020b using two fading channels: Rayleigh and 0 dB Echo. Finally, the acquired findings show a significant increase in system robustness when using the DVB-NGH BICM instead of the fundamental T2-Lite BICM module.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"394 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116225954","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 current hybrid beamforming structures can be categorized into two classes: fully-connected and sub-connected phase shifters. The former type includes a large number of phase shifters which results in an excessive energy consuming, while the later arrangement endures a serious spectral performance loss although of low energy consuming. This paper considers a low complexity algorithm to fulfill a sub-connected hybrid-BF which leverages an iterative optimization algorithm matrix vectorization property to update the baseband-BF and leverages the property of the feasible set for the passband-BF to drop the unit-modulus limits from the optimization task, and hence transform the matrix-problem into a simpler phase-rotated vector-problem to update the passband-BF. In addition, the initial beamforming vectors for the iterative process, i.e., the algorithm starting point, is determined from the optimal fully digital-BF according to the lest square error approach which assist in improving the convergence speed of the algorithm. We investigate the effects of different scheme parameters on the performance, which offer good insights for HP systems. The numerical results demonstrate the superior performance of the suggested designs compared to the some of the benchmark reference approaches. The simulation results show that the spectral efficiency of this algorithm is at least 54% higher than the traditional fully-analog algorithms at 5 dB SNR. Additionally, it increases energy efficiency by at least 36% compared with the orthogonal matching pursuit algorithm for number of RF-chain of 18.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124305412","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}
