What is interpolation artifacts?
Interpolation artifacts are a consequence of the inability of the most commonly used interpolation algorithms to properly represent aliased linear features in geophysical images (e.g., minimum curvature, Briggs, 1974; bidirectional, Yao and Rokne, 1996; and kriging, Hansen, 1993).
What is bicubic interpolation method?
Bicubic interpolation is a 2D system of using cubic splines or other polynomial technique for sharpening and enlarging digital images. It is commonly used in computer image editing software, by retouchers and editors when upscaling or resampling an image.
How many points are required for bicubic interpolation?
In contrast to bilinear interpolation, which only takes 4 pixels (2×2) into account, bicubic interpolation considers 16 pixels (4×4).
What is bicubic upscaling?
Image upscaling algorithms solve the task of filling missing pixels that contain information during the image enlargement process. The most common is a bicubic interpolation. This method doesn't draw any details. It just simulates new pixels from the values of the surrounding ones using a formula.
