Overview of techniques used for image resolution enhancement
Journal Title: International Journal on Computer Science and Engineering - Year 2012, Vol 4, Issue 7
Abstract
Image resolution enhancement is one of the first steps in image processing. Image resolution enhancement is the process of manipulating an image so that resultant image is more suitable than the original one for specific application. Image enhancement can be done in various domains. For image resolution enhancement there are many methods, out of which image interpolation scheme is one of the most effective method. However, resolution is vital aspect of any image. Good quality image i.e. high resolution image produces better result in image processing applications. An interpolation is the technique to increase the resolution of the image by selecting new pixel from surrounding one. Image interpolation in complex wavelet transform is produces better results for any imaging application. DTCWT technique is used to improve the resolution of any satellite image. The paper focuses on the different techniques that are used to increase resolution of the images and their comparative results.
