Abstract

As a result of bandwidth and storage limitations, image compression techniques are widely used in data transmission and data storage. Image compression attempts to reduce the number of bits required to digitally represent an image while maintaining its perceived visual quality. In this paper a simplified and more effective image compression method is described. A new technique is proposed for image compression depends on a known method in the field of medical imaging, especially in the magnetic resonance imaging (MRI) known as "K-Space" transformation, but used only in MRI image formation and was not used in image compression before. Simulation results show the effectiveness of the proposed method. The performance of this method is compared with the available jpeg compression technique over a wide number of images, showing good agreements.
