Abstract
The objective of this research is to develop a technique for improving the quality of enlarged images by adjusting the coefficients for the new pixels obtained from estimating or predicting values from the nearest neighboring 2 x 2 pixels to create the high-resolution and high-sharpness images, and anti-aliasing. The Interpolation Based Enhancement Technique (IE-T) has been developed based on the interpolation technique, which is a popular method for estimating the new pixels, and for solving problems in increasing the resolution of the image as well. The experimental results by evaluating the efficiency of the technique using the PSNR and SSIM show that the IE-T has average PSNR and SSIM values which are higher than the obtained values from other technique, and also has the ability to reduce the aliasing effects of the enlarged images. The research results demonstrate the effectiveness of the IE-T technique in increasing the resolution and sharpness of the enlarged images efficiently.
