Image Scaling Algorithm for Multimedia Applications

Shraddha Mali

This paper contains an adaptive edge enhancement algorithm proposed for two-dimensional (2-D) imagescaling application. The proposed image scaling algorithm consists of an edge detector, bilinear interpolation and low complexity spatial filter. The bilinear interpolation defines the intensity of the scaled pixel with the weighted average of the four nearest neighboring pixels, interpolated images become smooth and loss of edge information. The adaptive edge enhancement technique is used to protect the edge features effectively, to achieve better image quality and to avoid the loss of edge information. The filter attempts to reduce the noise, in blurred and distorted edges which are produced by bilinear interpolation. The analysis shows that edges are well preserved and interpolation artifacts (blurring) are reduced.Comparedwith the previous low-complexity techniques, this proposed method produces better quality required output images. To show the advantages of this system the PSNR values produced by different algorithms are compared.
