Research ArticleOpen accessIn the keywordsIn-Process Vision Inspection Systems for Sorting using Image Processing TechniquesJ. Latha, N. DevarajanProblem statement: Machine vision system is based on digital image processing and is found to be the best sensor detection as its operation is similar to the human eye. The purpose of machine vision is the desire to provide real time machines with visual abilities. Approach: A real time system is developed and is interfaced with the mechanical structure to … …Journal of Computer Science, Vol. 8, Issue 4 · 2 Feb 2012 · 7,075 accessesView PDFCite
Research ArticleOpen accessIn the keywordsColor Image Reconstruction Using A New R'G'I ModelAkram A. Moustafa, Ziad A. AlqadiProblem statement: A new color model for digital image was discussed; this model can be used to separate low and high frequencies in the image without loosing any information from the image. Approach: A comparative study between different color models (RGB, HSI) applied to a very large microscopic image analysis and the proposed model was presented. Such analysis of different … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,486 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDenoising Methods for MRI ImagerySamuel KozaitisThere are several new denoising algorithms that may be useful for magnetic resonance imaging. We compared the performance of some of the latest denoising algorithms with those that have been developed specifically for MRI imagery. We found that the latest approaches show impressive performance in terms of mean squared error, but a measure based on perceptual quality may be needed … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 30 Aug 2017 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Denoising Algorithms for Urban ScenesSamuel KozaitisSeveral new denoising algorithms have recently been presented that display comparable performance and it is unclear which provide the best results. We used the practical example of urban scenes to compare two of the top-performing algorithms. We found that when using the practical case of quantizing input and output imagery, the results were different than when using the conventional method … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 20 Jun 2017 · 7,849 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Edge Detection Techniques Applied in the Identification of Centerline Segregation on Steel SlabsLuciene Coelho Lopez Queiroz, André Riyuiti HirakawaThe method Baumann, or Sulphur print as it is also known, is one of the tools used to evaluate the operating conditions of continuous casting machine and quality control of the production of steel slabs. The correct evaluation of centerline segregation severity, analyzed in Sulphur print, is essential to control this process. However, given the classification complexity between the different … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 10 Sep 2015 · 6,821 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign of Low- Power High-Speed Error Tolerant Shift and Add MultiplierK. N. Vijeyakumar, V. Sumathy, Sriram Komanduri, C. Chrisjin Gnana SujiProblem Statement: In this study, we had proposed a low power architecture for high speed multiplication. Approach: The modifications to the conventional shift and add multiplier includes introduction of modified error tolerant technique for addition and enabling of adder cell by current multiplication bit of the multiplier constant. The proposed architecture enables the removal of input multiplexer, switching of adder … …Journal of Computer Science, Vol. 7, Issue 12 · 18 Oct 2011 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvancing Digital Forgery Detection: A Comparative Analysis of U-Net, Buster Net, Efficient B0+ U-Net, and VGG 16+ U-Net ModelsPreeti Dhiman, Usha ChauhanForgery Detection in the area of digital images is indispensable for insuring authenticity, particularly in detecting Copy-Move, Splicing. In this research, a meticulous analysis of latest learning architectures i.e. U-Net, Buster Net, Efficient B0+U-Net and VGG16+U-Net are compared for the detecting these types of forgeries. U-Net is popular due to its potent segmentation capabilities to provide pixel-level forgery localization while … …Journal of Computer Science, Vol. 22, Issue 10 · 8 Oct 2026 · 383 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced RoBERTa Model for OCR-Based EHR Parsing and Information ExtractionBalaji Ganesh Rajagopal, Amarnath C, Chidambaram Sawri Rajan, Deebalakshmi RamalingamHealthy source data for medical research and health analytics in general can be obtained from Electronic Health Records (EHRs). Nevertheless, due to the complexities of the design and especially the unstructured nature of them, it is not easy to extract important information from digital documents. This paper proposes a fundamentally new approach to the problem of interpreting EHRs obtained by … …Journal of Computer Science, Vol. 22, Issue 4 · 5 May 2026 · 1,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Method for Recognizing Face Expressions Based on Genetic Algorithm and Extreme Learning Based Hybrid ModelTushar Dhar Shukla, Md Oqail Ahmad, Puneet Sapra et al.The detection of facial action coding system Action Units (AU) and other facial expressions has been a major focus of computer science for more than 20 years categorizing discrete emotional states based on facial expressions. While several widely used face expression databases exist, standardization and comparability remain key challenges. The lack of a universally recognized assessment procedure and insufficient information … …Journal of Computer Science, Vol. 21, Issue 2 · 18 Jan 2025 · 7,293 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mother Plant and Somatic Embryo Registry for the Propagation and Conservation of Artificial Seeds of the Orchid Phragmipedium kovachiiOsber Cunia, Manuel Oliva, Segundo G. Chavez et al.Phragmipedium kovachii, is an endemic orchid that naturally inhabits the humid zones of the Amazonas region in Peru. Currently, it has been extracted from its natural habitat, listed as critically endangered by CITES, suggesting searching for conservation strategies in vitro and in situ. Therefore, this research established an in vitro protocol to obtain and conserve artificial seed, through four events: … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 8 Jul 2024 · 5,302 accessesView PDFCite
