The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...
In the image processing scenario the image enhancement takes high importance .Among so many image enhancement techniques the image enhancement is one of the main way. Visual information transmitted in the form of digital images is becoming a major method of communication in the modern age, but the image obtained after transmission is often corrupted with noise. The received image needs processi...
Enhancing Digital Images Through Cuckoo Search Algorithm in Combination with Morphological Operation
Corresponding Author: Ratna Babu, K. Department of CME SUVR and SR Govt. Polytechnic for Women, Ethamukkala, Prakasam Dt., India Email: [email protected] Abstract: This study presents an image enhancement approach to Cuckoo Search Algorithmin with Morphological Operation. At the present time, in many image processing applications digital images are developed. Machine vision, computer inte...
This paper presents a new, simple and robust image enhancement algorithm for image analysis by modifying the gamma value of its individual pixels. Considering the fact that gamma variation for a single image is actually nonlinear, the proposed method locally estimates the gamma values in an image. First, for local gamma correction the image is divided to overlapping windows and then the gamma v...
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...
The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...
Many images like medical images, satellite images, Arial images and even life photographs suffer from noise. Image enhancement techniques are used to improve the visual appearance of images by reducing noise from images. In this paper, a dynamic stochastic resonance (DSR) based algorithm is proposed to improve the visual quality by removing noise from digital image. Stochastic resonance (SR) is...
A new design method as a fusion of NewHisto algorithm & Pal-King algorithm based on traditional fuzzy image enhancement is proposed in this paper. The proposed method is used to improve the visual quality of low intensity images. In this method the image is processed differently at three stages. At the very first stage, Gamma Regulation technique is used then a recent NewHisto and above all fuz...
Modern endoscopes play an important role in diagnosing various gastrointestinal (GI) tract related diseases. The improved visual quality of endoscopic images can provide better diagnosis. This paper presents an efficient color image enhancement method for endoscopic images. It is achieved in two stages: image enhancement at gray level followed by space variant chrominance mapping color reproduc...
A histogram is a graphical representation of the distribution of data in an image. It is an estimate of the probability distribution of a continuous variable (quantitative variable). Histogram Equalization is a contrast enhancement technique in the image processing which uses the histogram of image. However histogram equalization is not the best method for contrast enhancement because the mean ...
