Within the last decades, improving the quality of an underwater image has received considerable attention due to poor visibility of the image which is caused by physical properties of the water medium. This paper presents a new method called mixture Contrast Limited Adaptive Histogram Equalization (CLAHE) color models that specifically developed for underwater image enhancement. The method operates CLAHE on RGB and HSV color models and both results are combined together using Euclidean norm. The underwater images used in this study were taken from Redang Island and Bidong Island in Terengganu, Malaysia. Experimental results show that the proposed approach significantly improves the visual quality of underwater images by enhancing contrast, as well as reducing noise and artifacts.

يعد تصنيف الجسم المتداخل أحد التحديات الرئيسية التي يواجهها الباحثون الذين يعملون في اكتشاف الأشياء والتعرف عليها. معظم الخوارزميات المتاحة التي تم تطويرها قادرة فقط على تصنيف أو التعرف على الأشياء التي تكون إما منفصلة بشكل فردي عن بعضها البعض أوجسم واحد في مشهد (مشاهد) ، ولكن لا تتداخل مع اجسام أدوات المطبخ. في هذا المشروع ، تم اقتراح خوارزميات Faster R-CNN و YOLOv5 لاكتشاف وتصنيف جسم متداخل في منطقة المطبخ. تم تطبيق YOLOv5 و Faster R-CNN على االاجسام المتداخلة حيث من المتوقع أن يتمكن المرشح أو النواة من فصل االجسم المتداخل في الطبقة المخصصة لتطبيق النماذج. تم استخدام قاعدة بيانات الصور المعيارية لأدوات المطبخ وأدوات المطبخ المتداخلة من الإنترنتااجسام مرجعية أساسية. تم تعيين مجموعات التقييم والتدريب / التحقق عند 20٪ و 80٪ على التوالي. قام هذا المشروع بتقييم أداء هذه التقنيات وتحليل نقاط قوتها وسرعاتها بناءً على الدقة والدقة ودرجةF1. خلصت نتائج التحليل في هذا المشروع إلى أن YOLOv5 ينتج مربعات إحاطة دقيقة بينما يكتشف Faster R-CNN المزيد من االاجسام. في بيئة اختبار مماثلة ، يُظهر YOLOv5 أداءً أفضل من خوارزمية R-CNN الأسرع. بعد التشغيل في نفس البيئة، حصل هذا المشروع...

A disposable screen-printed multi channel taste sensor composed of several types of lipid as transducers and a computer as data analyzer could detect taste in a manner similar to human gustatory sensation. The disposable taste sensor was used to measure the electrical potential resulted from the interaction between lipid membranes and taste substances. In the present study, two types of packaged commercial milk, the ultra high temperature (UHT) and the pasteurized milk were tested. It was found that the disposable taste sensor is capable to discriminate reliably between fresh and spoiled milk and to follow the deterioration of the milk quality when it is stored at room temperature based on a pattern recognition principle namely Principle Component Analysis (PCA). This research could provide a new monitoring method ideally for simple and cheap decentralized testing for controlling the quality of milk, which may be of great use in the dairy industries.

This paper presents an alternative approach for Content Based Image Retrieval (CBIR) using Scale Invariant Feature Transform (SIFT) algorithm for binary and gray scale images. The motivation to use SIFT algorithm for CBIR is due to the fact that SIFT is invariant to scale, rotation and translation as well as partially invariant to affine distortion and illumination changes. Inspired by these facts, this paper investigates the fundamental properties of SIFT for robust CBIR by using MPEG-7, COIL-20 and ZuBuD image databases. Our approach uses detected keypoints and its descriptors to match between the query images and images from the database. Our experimental results show that the proposed CBIR using SIFT algorithm producing excellent retrieval result for images with many corners as compared to retrieving image with less corners.

In data-intensive distributed systems, replication is the most widely used approach to offer high data availability, low bandwidth consumption, increased fault-tolerance and improved scalability of the overall system. Replication-based systems implement replica control protocols that enforce a specified semantics of accessing the data. Also, the performance depends on a host of factors chief of which is the protocol used to maintain consistency among object replica. In this paper, we propose a new low-cost and high data availability protocol for maintaining replicated data on networked distributed computing systems. We show that the proposed approach provides high data availability, low bandwidth consumption, increased fault-tolerance and improved scalability of the overall system as compared to standard replica control protocols.

Coral reefs are valuable ecosystems that face vulnerability to climate change impacts. Underwater images often encounter noise from various factors, such as water turbidity, lighting conditions, attenuation, and scattering, which can complicate edge detection and segmentation processes, leading to inaccuracies. However, image processing techniques offer a viable solution to this issue. In this study, an edge-based segmentation approach is proposed that uses multiple contrast techniques to detect and quantify changes in coral reef imagery. The proposed approach effectively identifies changes in coral reef imagery, making it a valuable tool for monitoring climate change's effects on these ecosystems. Furthermore, high-resolution images at different time points and locations were collected, and then an edge-based segmentation approach was utilized to enhance the accuracy of edge detection and segmentation. Comparing the proposed method with traditional segmentation techniques showed a significant improvement in terms of segmentation precision. Subsequently, alterations in the structure and composition of coral reefs are observed, indicating the influence of climate change on these ecosystems. This research highlights the capabilities of image processing techniques using edge-based segmentation in monitoring coral reefs. It offers an effective and precise approach to detecting changes in coral reef images, thereby contributing to conservation endeavors.
