Image enhancement improves the interpretability or perception of information in pictures for human viewers while also giving 'better' input for other automated image processing approaches.
i) SEM A scanning electron microscope (SEM) is a type of electron microscope that uses a focused beam of electrons to scan the surface of a sample to obtain photographs. When electrons contact with atoms in a sample, they produce a variety of signals that carry information about the sample's surface topography and composition.
ii) TEM Transmission electron microscopes (TEM) are microscopes that analyze objects and produce a greatly magnified picture using a particle stream of electrons. TEMs have a 2 million-fold magnification capability. Consider how little a cell is to gain a better picture of its size.
iii) Optical Microscopy Optical microscopy is a technique for seeing a sample up close using visible light and magnification using a lens. This is the classic type of microscopy, which was developed before the 18th century and is being used today. It can use for finding grain structures of samples.
