Image Enhancement is one of the most important and complex techniques in image processing technology. The main aim of image enhancement is to improve the visual appearance on an image and to offer a better representation of the image for Computer Vision Algorithms. In this paper,we is covered a few application fields of image enhancement with various images like grayscale, color, infrared and even with videos. The main objective of this paper is to highlight the drawbacks of the state of the art image enhancement techniques.

“…In the literature, modified versions of the hyperbolic algorithm for contrast enhancement can be found. These modified algorithms are suitable for the enhancement of magnetic resonance images, this technique uses controlled fashion of the grey level, which is stretched on the entire image [13]. Some contrast enhancement techniques are based on fuzzy techniques, fuzzy techniques can manage an image's imperfection, which is modelled as the uncertainty in the image, fuzzy methods for contrast enhancement (e.g.…”

Colour image enhancement plays an important role in image processing, computer vision and pattern recognition. Fuzzy logic techniques one of the methods used for digital image enhancement. In this study, Fuzzy Logic Based-on Sigmoid Membership Function (FLBSMF) was developed to improve lightness and contrast in coloured images. The FLBSMF algorithm was applied to the lightness component by using only the YIQ colour space, and the colour compounds were unchanged. The suggested algorithm was compared with other algorithms, such as fuzzy logic enhancement using membership function modification based on square operation, fuzzy logic based on histogram, histogram equalisation and multiscale retinex with colour restoration by using different criteria. Form the result the FLBSMF succeeded in enhancing colour images and it had good average values for entropy (7.44), mean square error in saturation (2.2E-08) and hue (8.11E-07), nature image quality (2.97) and lightness order error (0.90).

“…The proposed algorithm result proved as efficient and flexible for medical image enhancement and can be closed a pre-processing step for proper analysis and understanding of medical image. S.S.Chong [9] proposed an improved form of hyperbolic algorithm contrast enhancement technique suitable for magnetic resonance imaging (MRI). In this method contrast enhancement of image is done by controlled fusion of the gray level stretching on structure.…”

Image enhancement (IE) is the process of enhancing visual appearance of image in order to make it more effective for computer to process. The look and visibility of image rely on human eyes, which vary from one person to another. Several enhancement methods are used to improve the clarity of image, but different application require different types of techniques for enhancing image quality. In this review paper, we present different enhancement techniques categorized into spatial and frequency domain to classify image quality with its advantage and disadvantage.
