It is the intention of the author that this report serve as a strategic review of the potential for image processing techniques to aid the detection and classification of underwater mines and mine-like objects in various modes of sonar imagery. Image processing techniques to improve the performance of mine hunting operations using sector-scan, side-scan and the Acoustic Mine Imaging (AMI) proje...

is carried out on region basis. An imagery scene is modeled by the spectrally homogeneous regions restrained in shape and size. Given a set of low level image features for each region, perceptual grouping is performed on the regions to generate a higher level of structure, from which road segments are extracted. In our unique approach, perceptual grouping is based on the similarity of spectral,...

This paper proposes an improved dark channel prior for removing haze from images. Dark channel prior is an effective method for removing haze. Dark channel is an image in the same size as the hazy image which is obtained by dividing the RGB images into windows and for each window, the minimum of each R, G and B channels are calculated. Then again the minimum of these three values is calculated ...

Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

Using satellite and aerial imagery of Australian waveand storm-prone coastal areas, investigate a variety of image segmentation/classification techniques in GIS and other application environments. During the investigation, establish: (i) the suitability of the techniques for reliable classification of imagery, for instance into sand, rock and mud substrates, (ii) whether they can be implemented...

The image processing applications in which JPL's Image processing Laboratory is active range from planetary exploration and earth applications to biomedical applications, astronomy, and scene analysis for the robotic vehicles of the future. There are several common trends that are apparent that are common to each of these applications areas, and these trends are discussed in this paper. The tre...
