This field is gaining interest from researchers all over the world. This study is intended to utilize the Stockwell transform (ST) to investigate the classification accuracy of five different types of mental tasks. A well known electroencephalogram (EEG) database (Keirn and Aunon database) has been used in this study. Two subjects from the database were considered for the study. k-means nearest neighborhood (k-NN) and Linear Discriminant Analysis (LDA) based classifiers were used to perform a pair-wise classification of the 10 combinations of mental tasks. Two different discriminant functions such as linear and quadratic were used in LDA classifier and their effects on the classification performance are presented. The effect of different ‘k’ values (1 to 10) was also studied in kNN algorithm. Conventional and k-fold cross validation methods were used to investigate the reliability of the classification results of the classifiers. The experimental results show that the proposed method gives promising pair-wise classification accuracy from 78.80% to 100%.","PeriodicalId":247351,"journal":{"name":"2011 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115022228","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}

Gated imaging is a powerful technique to capture images in turbid condition. By controlling the time delay of the shutter to capture the returning light, we can obtain the image at different depth. Modular transfer function (MTF) is used to evaluate the quality of the gated images. Images with useful information (clear and sharp objects) are gathered. Then, the images are segmented into squares. Every segment of every image is analyzed using MTF. The segment with the best contrast is selected to be used in the final image. The best of each segment is gathered and are used to reconstruct a new image with most of the useful information preserved in them. Then, post-processing is done on the constructed gated image for a seamless image fusion. Seeded region growing is one of the image segmentation techniques. This technique is utilized to look for the region with the same feature and segment the images into regions. The constructed gated image provides an image with monotonous coloration. Therefore, seeded region growing technique easily identifies the borders where there is abrupt change in color feature. The segment edge is one of these borders. An algorithm is used to check for the edges of the segment. Then, the segment edges are chosen for further processing. Gaussian filter is applied to the rough edge of the segment with obvious contrast. Gaussian filter is useful to blur images so that the color histogram will show a smooth color distribution. After the filter is applied, the rough edges will appear smooth and the objective of seamless image fusion is achieved. The final image has the useful information preserved and the borders of the segment are not obvious.","PeriodicalId":247351,"journal":{"name":"2011 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133778649","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}
