Research ArticleOpen accessIn the abstractHyperspectral Remote Sensing for Tropical Rain ForestKamaruzaman Jusoff, Kasawani IbrahimProblem statement: Sensing, mapping and monitoring the rain forest in forested regions of the world, particularly the tropics, has attracted a great deal of attention in recent years as deforestation and forest degradation account for up to 30% of anthropogenic carbon emissions and are now included in climate change negotiations. Approach: We reviewed the potential for air and spaceborne hyperspectral … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractSkew Detection and Correction Technique for Arabic Document Images Based on Centre of GravityAtallah Mahmoud Al-Shatnawi, Khairuddin OmarProblem statement: Skew detection and correction is the first step process in the document analysis and understanding processing steps. Correction the skewed scanned document image is very important, because it has a direct effect on the reliability and efficiency of the segmentation and feature extraction stages. The noises and the deviation in the document resolution or types are still the … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of Stability Testing Approaches of Two-Dimensional Recursive Digital FiltersK. R. Santhi, M. Ponnavaikko, N. GangatharanThere are many problems in science and engineering whose solution is applied in the design of Multi-Dimensional (MD) digital filters. Digital filtering finds an important position in the field of digital signal and image processing. Recently there had been a great deal of interest in the design and stability analysis of Two-Dimensional (2-D) recursive digital filters. The design techniques for … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Average Contour of Thais Skulls for Design of ImplantsKhemachit Sena, Surasith PiyasinIn this study, 100 dry skulls of Thais collected at the Srinagarind Hospital in Khon Kaen, Thailand were CT scanned and served for the investigation of the geometric average contour of Thais skulls. Moreover, measurements of distances between landmark points on skulls (cranial anthropometry) were made with this set of skulls for future standardization of skull implants. Thus the main … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Traffic Light Sequence Algorithm Using RFIDKhalid A.S. Al-Khateeb, Jaiz A.Y. Johari, Wajdi F. Al-KhateebProblem statement: Traffic congestion and tidal flow management were recognized as major problems in modern urban areas, which have caused much frustration and loss of man hours. Approach: In order to solve the problem an intelligent RFID traffic control has been developed. It has circumvented or avoided the problems that usually arise with systems such as those, which use image … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 21,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Set of RST Moment InvariantsKhalid M. HosnyMoment invariants are widely used in image processing, pattern recognition and computer vision. Several methods and algorithms have been proposed for fast and efficient calculation of moment's invariants where numerical approximation errors are involved in most of these methods. In this paper, an optimized set of moment invariants with respect to rotation, scaling and translation is presented. An accurate method … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,069 accessesView PDFCite
Research ArticleOpen accessIn the abstractSugarcane Phenological Date Estimation Using Broad-Band Digital CamerasMobasheri, M. Chahardoli, J. Jokar, M. FarajzadehIn the agricultural industry, precision farming is the most important task that attracts lots of attentions. The health of the plant depends mostly on the amount of water in its access that can be estimated through vegetation indices. These indices can be extracted from satellite images through Image processing algorithms. The objective of this research was to provide an equation … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 7,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractIR Laser Plasma Interaction with GlassRabia Qindeel, Noriah Bidin, Yaacob Mat DaudThe interaction of laser plasma with respect to glass surface is reported in this paper. A Q-switched Nd:YAG laser was used as ablation source. Glass material is utilized as target specimen. Aluminum plate is used as a rotating substrate. The dynamic expansion of the plasma was visualized by using CCD video camera and permanently recorded via image processing system.

Research ArticleOpen accessIn the abstractLow Power Hardware Implementation of High Speed FFT CoreM. Kannan, S. K. SrivatsaApplications based on Fast Fourier Transform (FFT) such as signal and image processing require high computational power. This paper proposes the implementation of radix-4 based parallel-pipelined Fast Fourier Transform processor which incorporates a low power commutator, butter-fly with multiplier-less architecture. The proposed parallel pipelined architectures have the advantages of high throughput and low power consumption. The multiplier-less architecture uses shift … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,227 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModified U-Net With VGG11-BN Encoder and Frost Filter Based Pre-Processing for Copy Move Forgery LocalizationAshutosh Pandey, Niranjan Lal, Ashish Kumar ChakravertiCopy-move forgery is a widely used forgery method in digital image forensics, which involves copying and pasting a part of an image into another part of the image to hide or duplicate the visual information. This makes it difficult to detect such manipulations, particularly when the regions are subjected to geometric and photometric transformations. A Frost Filter-Enhanced Encoder-Decoder U-Net is … …Journal of Computer Science, Vol. 22, Issue 10 · 6 Oct 2026 · 457 accessesView PDFCite
