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.

Key stages in digital image processing include image acquisition, where the image is captured by a sensor; image enhancement, which improves visual quality through techniques like filtering and contrast adjustment; image restoration, aimed at recovering an image that has been degraded; and image analysis, where techniques such as segmentation and feature extraction are applied to interpret the content of the image. Finally, image representation and compression may be performed to store or transmit the image efficiently.
Image processing refers to the technique of manipulating and analyzing images to enhance their quality or extract useful information. This involves various algorithms and methods to perform tasks such as filtering, transformation, and restoration. The goal is to improve visual perception or facilitate automated analysis for applications in fields like medicine, remote sensing, and computer vision. Ultimately, image processing enables better interpretation and understanding of image data.
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.

A convex lense forms only a virtual image.
