4th International Conference on Recent Trends in Engineering & Technology(ICRTET-2015) July 2-4,2015 Organized by SNJB's KBJ College of Engineering,Chandwad,Nashik,Maharashtra,India

Abstract :

Images are being used in many fields of research. Resolution is the major issue of the images. The Image Enhancement is the main technique for improving the resolution and visual appearance of the image. A Resolution Enhancement technique is based on the Interpolation of the high-frequency sub bands obtained by Discrete Wavelet Transforms (DWT). Then, the highfrequency sub band images and the input low-resolution image are interpolated .Then all these images are combined and a new resolution image is formed by passing through inverse DWT. DWT preserves the high frequency components which helps to get a more sharper image.
