The ACO based image fusion technique is proposed. The objective function and distance matrix is designed for image fusion. ACO is used to fuse input images at the feature-level by learning the fusion parameters. It is used to select the fusion parameters according to the user-defined cost functions. This algorithm transforms the results into the initial pheromone distribution and seeks the optimal solution by using the features. As to relevant parameters for the ACO, three parameters (α, β, ρ ) have the greatest impact on convergence. If the values of α, β are appropriately increased, convergence can speed up. But if the gap between these two is too large, the precision of convergence will be negatively affected. Since the ACO is a random search algorithm, its computation speed is relatively slow.","PeriodicalId":23601,"journal":{"name":"VOLUME-8 ISSUE-10, AUGUST 2019, REGULAR ISSUE","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83517024","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 is a condition in which an\u0000individual is physically and mentally at rest. The conception of\u0000sleep is considered extremely peculiar and is a topic of discussion\u0000and researchers all over the world has been attracted by this\u0000concept. Sleep analysis and its stages is analyzed to be useful in\u0000sleep research and sleep medicine area. By properly analyzing\u0000the sleep scoring system and its different stages has proven\u0000helpful for diagnosing sleep disorders. As it’s seen, sleep stage\u0000classification by manual process is a hectic procedure as it takes\u0000sufficient time for sleep experts to perform data analysis. Besides,\u0000mistakes and irregularities in between classification of same data\u0000can be recurrent. Therefore, the use of automatic scoring system\u0000in order to support reliable classification is highly in greater use.\u0000The scheduled work provides an insight to use the automatic\u0000scheme which is based on real time EMG signals and Artificial\u0000neural network. EMG is an electro neurological diagnostic tool\u0000which evaluates and records the electrical activity generated by\u0000muscle cells. The sleep scoring analysis can be applied by\u0000recording Electroencephalogram (EEG), Electromyogram\u0000(EMG), and Electrooculogram (EOG) based on epoch and this\u0000method is termed as PSG test or polysomnography test. The\u0000epoch measured has length segments for a period of 30 seconds.\u0000The standard database of EMG records was gathered from\u0000various hospitals in sleep laboratory which gives the different\u0000stages of sleep. These are Waking, Non-REM1 (stage-1), NonREM2 (stage-2), Non-REM3 (stage-3), REM. The collection of\u0000data was done for the period of 30 second known as epoch, for\u0000seven hours. The dataset obtained from the biological signal was\u0000managed so that necessary data is to be extracted from\u0000degenerated signal utilized for the purpose of study. As a matter\u0000of fact, it is known electrical signals are distributed throughout\u0000the body and is needed to be removed. These unwanted signals\u0000are termed as artifacts and they are removed with the help of\u0000filters. In this proposed work, the signal is filtered by making use\u0000of low-pass filter called Butterworth. The withdrawn\u0000characteristics were instructed and categorized by utilizing\u0000Artificial Neural Network (ANN). ANN, on the other hand is\u0000highly complicated network and utilizing same in the field of\u0000biomedical when contracted with electrical signals, acquired\u0000from human body is itself a novel. The precision obtained by the\u0000help of the procedure was discovered to be satisfactory and hence\u0000the process is very useful in clinics of sleep, especially helpful for\u0000neuro-scientists for discovering the disturbance in sleep.","PeriodicalId":23601,"journal":{"name":"VOLUME-8 ISSUE-10, AUGUST 2019, REGULAR ISSUE","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74904029","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}
