Abstract

Image resolution enhancement algorithms, in spatial domain (viz., bicubic, data dependent triangulation and edge directed interpolation) and transform domain (viz., wavelet and DCT) were implemented and their performances were compared. It was concluded that discrete cosine transform (DCT) based image resolution enhancement algorithm performs better than the other methods. DCT based image resolution enhancement algorithm is very simple to implement and has the additional advantage of being able to produce high resolution images whose size need not necessarily be a multiple of two. DCT based video resolution enhancement algorithm was implemented and tested its performance in Simulink. It was concluded that this algorithm would be very suitable for video resolution enhancement.
