Interpolation-Based Enhancement Technique for Image Enlargement

Abstract

This research presents a technique to improve a quality of an image obtained by adjusting the coefficients for the new pixels obtained estimating or predicting values ​​from the neighbor pixels to create a new image that high-resolution and sharpness. The Interpolation Based Enhancement Technique (IBE-T) was developed based on the Bicubic technique, which is a method for estimating the new pixels that are popular and brought. Use to increase image resolutions. The results of evaluating the efficiency of the technique Using the PSNR and SSIM revealed the IBE-T technique had an average PSNR and SSIM which was better than other techniques, and had the ability to solve the aliasing from image enlargement. This demonstrated the effectiveness of the IBE-T to improve image quality, by estimating the image to grow effectively.
