What is interpolation in image processing?
you resize or remap your image from one pixel grid to another.
image processing In electrical engineering and computer science, image processing is any form of signal processing for which the input is an image, such as photographs or frames of video; the output of image processing can be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.

In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image Computer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer with help from specialized software andhardware
First, the image contains a nice mixture of detail, flat regions, shading, and texture that do a good job of testing various image processing algorithms. It is a good test image! Second, the Lena image is a picture of an attractive woman. It is not surprising that the (mostly male) image processing research community gravitated toward an image that they found attractive.

§ Image processing tends to focus on 2D images, how to transform one image to another by pixel-wise operations, such as noise removal, edge detection, etc. whereas computer vision includes 3D analysis from 2D images. § As inferred from above, image processing does not require any assumptions, nor does it produce any interpretations about the image content, whereas computer vision often relies on more or less complex assumptions about the scene depicted in an image…
