pixel interpolation

Pixel interpolation is a process used to estimate and create new pixel values when resizing or enlarging images. When an image is scaled up, the software calculates the colors and brightness of new pixels based on surrounding pixels to maintain a smooth and clear appearance. This involves analyzing neighboring pixel data to fill in gaps, resulting in a resized image that appears natural without abrupt edges or pixelation. Different methods, such as bilinear or bicubic interpolation, use varying levels of complexity to achieve the best balance between image quality and processing speed.
