A CAD system for diagnosing the mammograms is proposed in this work. The mammogram image is preprocessed using adaptive median filter and ROI is segmented using otsu's thresholding technique. Then the extracted GLCM features from ROI were given to the classifier. The classifiers such as SVM and KNN were used in this CAD system and the performance metrics were analyzed. The classification accuracy...
Breast cancer is one of the major cause of death among women in the whole world. Accurate detection and early diagnosis can increase a survival of the patients. In this paper, an efficient feature extraction method using curvelet transform and feature selection using swarm intelligence has been proposed. In this work, coefficients are extracted from the Region of Interest (ROI) mammogram images by...
This paper presents a novel feature extraction technique for an automatic classification of MRI brain tumor images. Wavelet based SFTA Feature extraction technique (WSFTA) consists of two steps: (i) Initially the input image is decomposed into different frequency sub band images using 2-D Discrete Wavelet Transform, (ii) the texture features are extracted from the decomposed Low frequency image using...
Web Spam is a portion of web page which has been created with the intention of increasing its ranking in search engines. Web spamming [4] refers to actions intended to mislead search engines into ranking certain pages higher than they deserve. Recently, the amount of web spam has increased dramatically, leading to a degradation of search results. And also the web spam takes large amount of disk space,...
Over the past three decades, Micro-Electro-Mechanical Systems (MEMS) have provided advancements in different fields of electronics. MEMS technology also enabled microwave and antenna engineers to produce some existing and novel radio-frequency components resulting as a new research field, namely RF MEMS. The use of MEMS technology for RF and microwave applications promises to solve many limitations,...
Search Engine spam is a web page or a portion of a web page which has been created with the intention of increasing its ranking in search engines. Web spamming refers to actions intended to mislead search engines and give some pages higher ranking than they deserve. Anyone who uses a search engine frequently has most likely encountered a high ranking page that consists of nothing more than a bunch...
Computer based assessment is a prevalent method of administering the tests in the education environment. Randomization of test items here may produce unfair effect on test takers which is unproductive in the outcome of the test. Hence, the Intelligent Tutoring System came in to existence which assigns intelligent question depending on the student's response in the testing session. It will be more...
