Research ArticleOpen accessIn the author namesTesting Image Encryption by Output Feedback (OFB)Yas A. AlsultannyWhen it is necessary to securely transmit data in open networks, the encryption must be performed. Most of the cryptographic algorithms were mainly developed for text data. Unfortunately, algorithms those are good for textual data might not suitable for image. The OFB mode of encryption implemented to test five images of different resources, by using three combinations (schemes): a combination … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the author namesLaser Beam Analysis Using Image ProcessingYas A. AlsultannyThe laser beam profiles captured by CCD camera processed and analyzed by using 2D- graphic and displayed on the monitor. The analysis of the He-Ne profiles and laser diode profiles are presented. The results showed that the He-Ne laser emits a pure Gaussian beam, whereas the diode laser emits an elliptical beam shape. The laser beam profile analysis developed to … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the author namesEdge Defection Prediction by Using Wavelet CompressionYas A.K. AlsultannyDigital image have been expanding in usage. The importance of image compression algorithms have been increased, to produce smaller file size with a lower computational requirement. The wavelet transform offers a natural decomposition of images at multiple resolutions, since the wavelet transform can decompose images into various multiresolution subbands, where the correlation exists. A novel technique for image compression by … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,292 accessesView PDFCite
