Image Upscaling Using Bilinear Interpolation and Quadratic Surface Interpolation

Upscale images using bilinear interpolation or quadratic surface interpolation techniques, followed by color self-snake model application to eliminate edge blurring and aliasing artifacts. Implementation considerations include pixel weighting algorithms and curvature-preserving surface fitting.

Sinc Interpolation in the Frequency Domain for 2D Signals

This method performs sinc interpolation on the frequency domain of 2D signals to achieve image magnification, producing high-quality results with minimal aliasing artifacts.
