Research ArticleOpen accessEvery word in the titleAutomatic Detection of Exudates in Retinal Images using Region-Based, Neighborhood and Block OperationKittipol Wisaeng, Worawat Sa-NgiamviboolExudates detection is one of the research areas attracting great attention of physicians and scientists. A region-based, neighborhood, block operation and optimal global thresholding are proposed as new methods to exudates detection. The exudates are coarse and fine segmentation following preprocessing steps, i.e., color mapping, image contrast enhancement, fuzzy filtering and optic disc localization. To classify the retinal images into … …Journal of Computer Science, Vol. 14, Issue 4 · 21 Feb 2018 · 7,987 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleFractal Images Compressing by Estimating the Closest Neighborhood with Using of Schema TheoryMahdi Jampour, Mahdi Yaghoobi, Maryam AshourzadehProblem statement: One of the methods used for compressing images and especially natural images is by benefiting from fractal features of images. Natural images have properties like Self-Similarity that can be used in image compressing. The basic approach in compressing methods is based on the fractal features and searching the best replacement block for the original image. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,902 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDISTINGUISHABILITY BASED WEIGHTED FEATURE SELECTION USING COLUMN WISE K NEIGHBORHOOD FOR THE CLASSIFICATION OF GENE MICROARRAY DATASETJeyachidra, PunithavalliIn data mining, much research is being carried out to discover the previously unknown, valid, novel, useful and understandable patterns in large databases. The patterns must be actionable so that they might be used for decision making to a variety of applications in healthcare. In this study, feature subset selection is an important area, where many approaches have been proposed. … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 13 Nov 2013 · 6,801 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleSocial Inclusion and Local Development through European Voluntourism: A Case Study of the Project Realized in a Neighborhood of MoroccoIsabel Novo Corti, Priscila Nogueira Marola, Manoel Bana CastroProblem statement: Tourism is an important activity in the global economy that drives thousands of people each year through all continents of the world and generates employment and income. Its economic impacts affect on agents that are directly involved in the sector, transferring to other sectors and destinations on an indirect way, characterizing it as a transverse activity that affects … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 9,514 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMultiresolution Laplacian Sparse Coding Technique for Image ClassificationIntidhar Jemel, Ridha Ejbali, Mourad ZaiedSparse coding is a set of techniques used for learning a collection of over-complete bases to represent data efficiently. This technique has been used in different domain such as feature quantization and image classification. Despite its capacity of modeling, it could not represent similarity of the image coding which cause a poor performance in locality. The cause of this limitation … …Journal of Computer Science, Vol. 14, Issue 8 · 23 May 2018 · 7,927 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,391 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPrivacy and Social Interaction in Traditional Towns to Contemporary Urban Design in IranSamira Ramezani, Shima HamidiPrivacy as an inherent feature of Iranian culture is evident in formation of Iranian traditional towns. Put differently, attention to the inside was one of the most desirable principles in Iranian traditional architecture as well as urbanism. However, privacy did not lead to isolation in Iranian culture and social contact was also of a great importance to Iranians.

Research ArticleOpen accessIn the keywordsHybrid Enhanced Neighbourhood and Latent Factor Model for Cold-Start RecommendationsAmritha P, Rajkumar KKAmong different recommendation strategies, collaborative filtering remains a commonly utilized method for generating personalized suggestions. The traditional collaborative algorithms face performance declines due to the sparse rating of data and the item cold-start problem. To overcome these challenges, this paper introduces a novel hybrid model called HCE-KNNCF (Hybrid Cognition-Enabled K-Nearest Neighbor Collaborative Filtering). The proposed model generates predicted rating by … …Journal of Computer Science, Vol. 22, Issue 9 · 21 Sep 2026 · 630 accessesView PDF Cite
