Image resampling is the process of changing the size or resolution of a digital image. This can involve either enlarging or reducing the number of pixels in the image, which affects its quality and clarity. When an image is resampled, new pixel values are calculated based on the original pixels, which can lead to a smoother appearance or loss of detail, depending on the method used. There are different techniques for image resampling, including nearest neighbor, bilinear, and bicubic interpolation. Each method has its own advantages and disadvantages, impacting the final look of the image. Choosing the right technique is essential for achieving the desired visual outcome.
