The Use of Biharmonic Dejdamrong Surface in Gray Image Enlargement Process

In this given study, the image enlargement method was investigated from the perspective of making use of biharmonic cubic Dejdumrong surfaces. It is common practice to resize a picture by upsampling or downsampling in order to accommodate a tiny image on a bigger screen (full-screen mode) or to decrease a high-quality image to a lower resolution. In contrast, this study will focus on picture enlargement utilizing a scaling factor of two owing to certain limitations. Biharmonic cubic Dejdumrong was employed in the investigation under various four-boundary curve conditions. This research looked at the effectiveness of the recommended approach by applying it to well-known grayscale test photos and calculating the peak signal-to-noise ratio (PSNR), which is an indication of how well the strategy performed.
