Virtual restoration is a digitally restored version of a piece of art. This technique is used to describe a method by which an artwork can be cleaned. It basically shows how the artwork will look after cleaning.
1. Image acquisition 2. Image restoration/enhancement 3. Image segmentation 4. Image interpretation
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
Its called a virtual image.

A virtual image is always upright in relation to the object.
A negative sign is associated with a virtual image because the light rays do not actually converge at the location of the virtual image. Instead, they appear to diverge from a point behind the mirror or lens, creating the virtual image. Mathematically, this distance is represented as negative to indicate the direction of the virtual image.
A plane mirror forms a virtual image. If it's reflected, then the light does not come from the image, and it is virtual.
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)
a virtual image
image processingIn 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.
A convex lense forms only a virtual image.
