Using global contrast enhancement, low contrast image can be improved in its quality globally. The enhanced output image, with such type of enhancement, may not have the noise and ringing artifacts. However, it may have over-exposure on some parts of the image and under-exposure on some other parts of the image when too high contrast gain occurs. Besides these, the enhanced output image may lac...
Image enhancement technique plays vital role in improving the quality of the image. Enhancement technique basically enhances the foreground information and retains the background and improve the overall contrast of an image. In some case the background of an image hides the structural information of an image. This paper proposes an algorithm which enhances the foreground image and the backgroun...
In image enhancement various enhancement schemes have been used for enhancing which includes gray scale manipulation, filtering and Histogram Equalization (HE). Histogram equalization techniques using fuzzy logic is one of the unique image enhancement technique. It became a popular technique for contrast enhancement because this method is simple and effective. In the latter case, preserving the...
This paper studies various research contributions in the field of contrast enhancement of medical images. Medical images such as X-rays, ultrasound and others are used in the analysis and diagnosis process by physicians and radiologists. If the image quality is not good and contrast is poor then the diagnosis result is badly affected. Therefore, this paper attempts to review the research papers...
We describe advanced video technologies for image reconstruction and enhancement. Sophisticated image reconstruction methodologies can enhance and improve the image quality of lower-resolution video. White Paper Advanced Media Functions
Surface roughness measurement is widely used to estimate the quality of the product during manufacturing processes. It has a great importance in manufacturing fields such as ceramic tiles, glass, and iron. Many are using surface profile-meter with a contact stylus to measure the surface roughness of work piece. In the stylus method, a stylus is moved along the surface and the vertical movement ...

The principle of image enhancement is to improve the interpretability of information contained in the image for human perception or to provide a more suitable input for automated image processing systems. Many images like medical images, satellite images, aerial images and natural images suffer from contrast and noise issues. It is necessary to enhance the contrast and remove the noise to incre...
Principle objective of Image enhancement is to process an image so that result is more suitable than original image for specific application. Digital image enhancement techniques provide a multitude of choices for improving the visual quality of images. Appropriate choice of such techniques is greatly influenced by the imaging modality, task at hand and viewing conditions. This paper will provi...
Satellite Images are used in many fields of research and enhancement of these images is a very important process. Satellite image enhancement is done using various transform techniques, filters and interpolation methods. This paper discusses a method of satellite image enhancement using Curvelet transform and interpolation technique. The quality of the enhanced image is measured using parameter...
