Moreover, aforesaid approaches performances are estimated impartially remnants the huge confront that might delay the furthermore improvement of developed image restoration techniques. Hence, an efficient noisy pixel prediction on the basis of the image restoration is introduced that uses the Deep Convolutional Neural Network (DCNN) classifier to restore the input image from several noises, such as random noise as well as impulse noise. An Improved Harmony Search Algorithm (IHSA) is adopted to train the DCNN optimally based on minimum error. After identifying the noisy pixels, by exploiting the neuro-fuzzy system the enhancement of pixel is performed. Finally, the experimental analysis is performed and the image restoration performance on the basis of IHSA is analyzed based on the SDME, PSNR, and SSIM. Ultimately, the adopted model attains the maximum PSNR SSIM for images with random noise, as well as maximum SDME with impulse noise, correspondingly.","PeriodicalId":167187,"journal":{"name":"Multimedia Research","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123049636","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}

A novel approach to interference alleviation was developed in this paper for 3D antenna array models in OFDMA as well as multi-cell MIMO wireless networks. Therefore, in the 3D MIMO-OFDM system, the Dynamic vertical beamforming is exploited to the cell degree separation user-specific down tilts user. The major contribution of this paper is to maximize the cell edge user’s throughput as well as cell center users. Here, the single objective function is the specified multi-objective model that is resolved using the adoption of a novel enhanced approach. This optimization issue is solved using the fine-tuning of particular parameters like RB allocation, allocated power for RB, and cell edge user. A hybrid Whale Optimization Algorithm (WOA) and Grey Wolf Optimization (GWO) algorithm referred to as the Hybrid WOA-GWO approach is used to attain the fine-tuned parameters.

Nevertheless, the cloud computing environment occurs several security problems in recognizing the anomalous network behaviors with respect to the existing threats. An effectual Intrusion Detection System (IDS) called a hybrid Grasshopper Optimization (GSO) algorithm with Bat Algorithm (BA)-based DBN is developed to identify suspicious intrusions in cloud environments in order to solve security problems. By exploiting the fitness function the optimal solution to detect the intrusion is shown that recognizes the minimum error value as the optimal solution. Moreover, using adopted optimization approach is used to tune the weights optimally to produce an effective and best solution to detect the intruders.
