Research ArticleOpen accessIn the abstractA Shuffle Image-Encryption AlgorithmA. A. Yahya, A. M. AbdallaProblem statement: Image encryption needs to be secure by resisting statistical attacks and other types of attacks. Approach: The new algorithm, call it the Shuffle Encryption Algorithm (SEA), applies nonlinear s-box byte substitution. Then, it performed a shuffling operation partially dependent on the input data and uses the given key. Results: SEA was implemented and tested with different data, mainly … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Jul 2009 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Approach for Detection and Recognition of VehiclesK. S. Selvanayaki, Rm. SomaSundaramOn road vehicles have increased in numbers and monitoring them is a challenging task. In common areas of public crowd people and vehicles are common objects for monitoring. The proposed system aims at detecting number plate information indicating the possibility for security relevant issues. Existing system performs recognition mainly by using license plate alone.

Research ArticleOpen accessIn the abstractA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,308 accessesView PDFCite
Research ArticleOpen accessIn the abstractHead Gesture Analysis using Matrix Group Displacement AlgorithmMahmoud Z. IskandaraniA novel algorithm for head gestures interpretation is designed and tested. The designed system carries out gesture detection and recognition using the MGDA algorithm, which implements random sampling and importance sampling, such technique can track head poses and estimate head positions. Problem statement: Head position is an important indicator of a person’s focus of attention, which can be used as … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Detection and Classification from Thermal Images Using Region based Convolutional Neural NetworkUsha Mittal, Sonal Srivastava, Priyanka ChawlaIn recent years, object detection and classification has gained so much popularity in different application areas like face detection, self- driving cars, pedestrian detection, security surveillance systems etc. The traditional detection methods like background subtraction, Gaussian Mixture Model (GMM), Support Vector Machine (SVM) have certain drawbacks like overlapping of objects, distortion due to smoke, fog, lightening conditions etc. In this … …Journal of Computer Science, Vol. 15, Issue 7 · 18 Jul 2019 · 9,454 accessesView PDFCite

The skin color, region-props and bounding-box are used as preprocessing tools … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 17 May 2016 · 7,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Approaches to Ancient Crypto-Steganography MethodsA. Joseph Raphael, V. SundaramProblem statement: The requirement and ability to hide information from others has existed in the world for centuries. Cryptography and steganography are the most commonly used techniques for information sharing. The science of securing a data by encryption is cryptography whereas the method of hiding secret messages in other media is Steganography, so that the secret’s very existence is concealed. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 4 Nov 2011 · 8,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Government for Ecotourism Development: Focusing on East Coast Economic RegionMd. A.H. Bhuiyan, Chamhuri Siwar, Shaharuddin M. Ismail, Rabiul IslamProblem statement: This study explored the plans and strategies of government for ecotourism development in Malaysia as well as ECER. Government participation is necessary in developing economies where tourism planning and promotion tend to be controlled directly by governments. The ecotourism activity should have a strong focus on learning through interpretation of local ecosystems and cultural heritage. Malaysia has formulated … …Journal of Social Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 14,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical Assessment of Watermarked Medical ImagesJasni Mohamad Zain, Abdul Rani M. Fauzi, Azian A. AzizProblem statement: Digital watermarking provides security to medical images. Watermarking in Region Of Interest (ROI) however distorts medical images but it is known that the resulting loss of fidelity is visually imperceptible. Approach: Clinical assessment will objectively evaluate the distortion on medical images to see whether or not medical diagnosis is altered. We used 75 medical images consisting of x-rays, … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeparable Watermarking Technique Using the Biological Color ModelDavid Nino, Moussa Abdallah, Bassam HammoProblem statement: The issue of having robust and fragile watermarking is still main focus for various researchers worldwide. Performance of a watermarking technique depends on how complex as well as how feasible to implement. These issues are tested using various kinds of attacks including geometry and transformation. Watermarking techniques in color images are more challenging than gray images in terms … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,616 accessesView PDFCite
