Research ArticleOpen accessIn the keywordsAn Evaluation of Thermal Imaging Based Respiration Rate Monitoring in ChildrenFarah AL-Khalidi, Reza Saatchi, Heather Elphick, Derek BurkeProblem statement: An important indicator of an individual’s health is respiration rate. It is the average number of times air is inhaled and exhaled per minute. Existing respiration monitoring methods require an instrument to be attached to the patient’s body during the recording. This is a discomfort to the patient and the instrument can be dislodged from its position. Approach: … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Jul 2012 · 10,531 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Ultrasonication on Milk Fat Globule Size and Inhibition of Salmonella enteritidis GrowthUmiatin Umiatin, Dalia Sukmawati, Taryudi Taryudi et al.One significant effect of ultrasonic treatment is the inactivation of microorganisms. This characteristic causes ultrasound to be widely used in food processing, healthcare devices, and water treatment. Ultrasonication is an innovative technology that holds promise for accelerating processes and producing high-quality products. The ultrasonic process in milk processing includes homogenization and sterilization. Milk homogenization standardizes fat globule size, while sterilization … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 8 May 2026 · 1,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Computational Efficiency Analysis of LSB and Hybrid Steganographic MethodsDivya Sharma, Chander PrabhaElectronic Medical Images (EMI) are of various types such as X-rays, CT scans, MRIs, etc. EMIs are generally large, but they vary in dimensions and sizes based on the body part to which they belong. Not much research has been done to secure EMIs due to their varied and large sizes, while ensuring their accessibility for real-time transmission. Where access … …Journal of Computer Science, Vol. 21, Issue 10 · 28 Nov 2025 · 2,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrengthening Image Security with Unimodular Hill Cipher and Advanced Encryption StandardSamsul Arifin, Dwi Wijonarko, Monica Mayeni Manurung et al.Digital data security has become increasingly important with the growth of digital image usage, which often contains sensitive information. This study aims to enhance the security of digital images by combining Unimodular Hill Cipher (UHC) and Advanced Encryption Standard (AES) methods. UHC, a matrix-based symmetric encryption algorithm, is used for image matrix encryption, while AES provides an additional layer of … …Journal of Computer Science, Vol. 21, Issue 5 · 22 Apr 2025 · 5,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractRed-Green-Blue Color Analysis Concerning Rice Husk Incorporation in Rice BranIman Hernaman, Urip Rosani, Tidi Dhalika et al.We aimed to determine rice husks incorporated in rice bran by using Red-Green-Blue (RGB) color. Rice bran and rice husk samples were analyzed for crude protein and lignin and mixed at a ratio of 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50. The phloroglucinol-HCl was added to the samples into Petri dishes and photographed with a smartphone to get RGB pixel … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 30 May 2024 · 5,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Image Thresholding Using the Complement FeatureSalah AmeerA novel Eigen formulation is proposed for image segmentation. Each pixel is represented by a unit vector having the x-component as the normalized gray value of the pixel. The axes of inertia are simply the Eigen vectors of the auto-correlation matrix. The largest Eigen vector is used as the point of split. Each sub-image is further split in the same … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 5,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Thresholding Using the Complement FeatureSalah AmeerA new feature (the complement feature) is proposed in an Eigen formulations for performing global image thresholding. The goal is to find an intensity or gray-level value below which is the background while above it is the foreground (object). Each pixel in the image is represented by a (2D) unit vector where the x-component is the normalized (to [0,1] or … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 8 Jun 2020 · 6,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Density Salt and Pepper Noise Filter based on Shepard Interpolation MethodChaipichit Cumpim, Rachu PunchalardThis paper has proposed the technique in order to remove salt-and-pepper noise from the corrupted image. The proposed scheme consists of two steps. The first, the adaptive median filter is applied to noisy image for detecting noisy and noise-free pixels. Finally, the output image of previous step will be divided into many non-overlapping windows of which the noise-free pixel values … …Journal of Computer Science, Vol. 13, Issue 7 · 20 Jul 2017 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing the Robustness of Visual Degradation Based HAM Reversible Data HidingHabiba Sultana, A.H.M. Kamal, Mohammad Mahfuzul IslamPurposely visual degradation of image quality is a newfangled idea in the area of Histogram Association Mapped (HAM) reversible data hiding. Such scheme first divides the color scale, i.e., 0-255, into some partitions by the range, difference of minimum and maximum value of a block. Next, the histogram of a block resided to a partition, original partition, is moved, e.g., … …Journal of Computer Science, Vol. 12, Issue 2 · 26 Mar 2016 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractBone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) Software: A Pilot Study of the Analysis of Bone Density using Digital Dental X-RaysAdriane Yaeko Togashi, Adair Santa Catarina, Lucas Renato Piana Batistussi, Guilherme CoelhoThe Bone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) software was designed to determine jaw bone quality using digital dental X-rays. In order to identify patients with a suspicion of low bone density, a system was developed to evaluate bone microarchitecture through the analysis of samples collected in digital panoramic X-rays. The samples were collectedat two sites of the mandible: alveolar … …Current Research in Dentistry, Vol. 6, Issue 2 · 23 Feb 2016 · 7,471 accessesView PDFCite
