A research article reports the results of original research, assesses its contribution to the body of data during a given area, and is published during a peer-reviewed scholarly journal. A given academic field will likely have dozens of peer-reviewed journals. However, writing a search paper also can be an excellent opportunity to explore a subject that's particularly interesting to you. The research process allows you to realize expertise on a subject of your choice, and therefore the writing process helps you remember what you've got learned and know it on a deeper level The aim of image enhancement is to enhance the interpretability or perception of data in images for human viewers, or to supply `better' input for other automated image processing techniques. Image enhancement techniques are often divided into two broad categories. Spatial domain techniques, which operate directly on pixels, Frequency domain techniques, which operate the Fourier transform of a picture. Log Transformation Technique: Log transformation is one among the elementary image enhancement techniques of the spatial domain which will be effectively used for contrast enhancements of dark images. The log transform is actually a gray level transform which suggests that the grey levels of image pixels are altered. Power Low Transformation Technique: Stevens' law transformation is another commonly used gray level transformation in the spatial domain. It is conceptually almost like alpha rooting within the frequency domain as this is often done by raising the input grey level by some power.
