Image fusion is the process of merging two or more images obtained from the same sensor at different times or from two or more sensors at the same instant. The objective is to obtain more information from the fused image than from the individual images. In satellite images, the lower spatial resolution multispectral images are fused with higher spatial resolution panchromatic images. The fusion...

The ability of a spatial deconvolution algorithm to enhance reconstructed optical tomographic image quality was previously demonstrated. Here, additional computational studies show that introduction of complex medium geometry actually can improve the method’s performance. ©2006 Optical Society of America OCIS codes: (100.6950) Tomographic image processing; (100.6890) Three-dimensional image pro...

The aim of image enhancement is to improve the interpretability or perception of information in images for human viewers, or to provide `better' input for other automated image processing techniques. Image Enhancement process is use to enhances the original image into the good image according to quality. The aim is to enhance the features of original image for the better output. In this paper, ...

Because of light scattered by the suspended particles in the atmosphere, photographs taken in the foggy day look gray and lack of visibility. In order to unveil the clear image’s structures and colors, we propose a image defogging algorithm of single color image based on wavelet transform and histogram equalization. Firstly, using histogram equalization to enhancement image, then to nonlinear e...

Edges represent discontinuities of image intensity in an image. High level digital image processing such as object recognition, segmentation and robot vision depend on the accuracy of edge detection. Adding product of the detected image edge and a scaling constant k to the original image is useful for image edge enhancement for better visual perception. Numerical Experiment on high pass spatial...

w w w . i j c s t . c o m Abstract Image enhancement in Spatial Domain is the process of improving the quality of a digitally stored image by manipulating the image pixel values with the help of software. Manipulation of pixel values includes point operations, where each pixel is modified according to a particular equation that is not dependent on other pixel values so that result is more suita...

Recent literatures show how modified particle swarm had achieved its name and fame over its parental algorithm called as PSO by optimizing. In this paper we exploit its advantage over image enhancement for improving image contents. This makes handy for visualizing the information from enhanced images. Work deal with use of parameterized transformation and objective function for local/global inf...

The purpose of this research paper is to define a critical step in studying the statistics of fingerprint minutiae to reliably extract minutiae from the fingerprint images. It is necessary to employ the image enhancement techniques prior to minutiae extraction to obtain a more reliable estimate of the minutiae locations. Thus, fingerprint Image enhancement is to make the image clearer for easy ...

The use of modified version of PSO had declared the optimum solutions and act as remedy incase of particle stagnation. Traditional PSO lost its identity due to impact and strength of MPSO. Recent literatures show how modified particle swarm had achieved its name and fame over its parental algorithm called as PSO by optimizing. In this paper we exploit its advantage over image enhancement for im...

In order to improve contrast and restore color for underwater image captured by camera sensors without suffering from insufficient details and color cast, a fusion algorithm for image enhancement in different color spaces based on contrast limited adaptive histogram equalization (CLAHE) is proposed in this article. The original color image is first converted from RGB color space to two differen...
