PDF A new scheme of unsharp masking for image contrast enhancement is presented. An adaptive algorithm is introduced so that a sharpening action is performed only in locations where the image... Adaptive histogram equalization (AHE) is a computer image processing technique used to improve contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the

CONTRAST ENHANCEMENT TECHNIQUES USING ISTOGRAM
Image enhancement methods are widely used for improving the feature and quality of the images. Researchers have designed various contrast enhancement methods in the past. But since underwater image contain low contrast and resolution due to poor visibility conditions and refractions of light rays. Thus analysis and identification of the underwater object is a challenging and difficult task.

  • The library contains some basic image processing functionality, including point operations, filtering with a set of built-in convolution kernels, and colour space conversions. The library also supports image resizing, rotation and arbitrary affine transforms. There's a histogram method allowing you to pull some statistics out of an image. This can be used for automatic contrast enhancement
  • Medical imaging applies a lot of digital image processing techniques for better interpretation. Different enhance- ment techniques are available in literature for improving the quality of medical images. The major challenge in this area is that a specific algorithm which gives better results for a particular type of application may fail in giving good results for another type of application
  • standard image processing techniques (e.g., histogram equalization or linear contrast stretch). The subset is then displayed separately to highlight certain features that would have been impossible to discern in a global enhancement mode. The goal of this study was to develop automated procedures for feature based image enhancement techniques for rapid display purposes, especially of high
  • Contrast enhancement plays an important role in the im- provement of visual quality for computer vision, pattern recog- nition, and the processing of digital images.
