• ### Image fusion technique based on non-subsampled contourlet transform and adaptive unit-fast-linking pulse-coupled neural network

Publication Year: 2011, Page(s):113 - 121

| | PDF (509 KB)

A new image fusion technique based on non-subsampled contourlet transform (NSCT) and adaptive unit-fast-linking pulse-coupled neural network (PCNN) is presented. By using NSCT, multi-scale and multi-direction sparse decompositions of the source images are performed. Then, the basic PCNN model is improved to be an adaptive unit-fast-linking PCNN model, which synthesises the advantages of both unit-... View full abstract»

• ### Efficient saliency detection based on gaussian models

Publication Year: 2011, Page(s):122 - 131
Cited by:  Papers (4)
| | PDF (938 KB)

This study presents an efficient saliency model mainly aiming at content-based applications such as salient object segmentation. The input colour image is first pre-segmented into a set of regions using the mean shift algorithm. A set of Gaussian models are estimated on the basis of segmented regions, and then for each pixel, a set of normalised colour likelihood measures to different Gaussian mod... View full abstract»

• ### Algorithm to decompose three-dimensional complex structures at the necks: tested on snow structures

Publication Year: 2011, Page(s):132 - 140
| | PDF (860 KB)

The separation of overlapping particles in three-dimensional images is an image processing task with many fields of application. However, commonly used image processing algorithms have difficulties to identify the single particles and their connections in certain structures. Here the authors present an alternative algorithm for part decomposition, which performs better on some structures than comm... View full abstract»

• ### Efficient fusion for infrared and visible images based on compressive sensing principle

Publication Year: 2011, Page(s):141 - 147
Cited by:  Papers (13)
| | PDF (485 KB)

In this study, the potential application of compressive sensing (CS) principle in the image fusion for infrared (IR) and visible images is studied. First, the theory of CS is introduced briefly. Some comparative analyses of different reconstruction techniques are carried out in view of their performance in multisensor image recovery and the minimum number of sampling measurements one has to take t...

• ### Segmentation of textured cell images based on frequency analysis

Publication Year: 2011, Page(s):148 - 158
| | PDF (657 KB)

A novel frequency analysis algorithm for segmentation of textured cells is presented. The algorithm is developed based on an ideal simulation model and is applicable to real cell images. A simulated cell image is assumed to have an ellipse-like region of textured interior embedded in a relatively flat background. The size of the original image is expanded multiple times by extrapolating it to addi... View full abstract»

• ### Segmentation of noisy colour images using cauchy distribution in the complex wavelet domain

Publication Year: 2011, Page(s):159 - 170
Cited by:  Papers (5)
| | PDF (1022 KB)

This study proposes a novel image segmentation technique for noisy colour images, in which the heavy-tailed characteristics of the image are modelled by Cauchy distributions. First, the RGB colour bands of the noisy image are decomposed into multiresolution representations using the dual-tree complex wavelet transform. For each wavelet subband, a model is built assuming that the input coefficients... View full abstract»

• ### Digital image processing approach using combined wavelet hidden markov model for well-being analysis of insulators

Publication Year: 2011, Page(s):171 - 183
Cited by:  Papers (3)
| | PDF (698 KB)

This study employs a digital image processing (DIP) technique for video surveillance (VS) of overhead power distribution line insulators. Such VS technique is one of the promising means for augmenting the process of distribution system automation (DSA). Particularly in semi-urban areas and as well as urban areas in developing countries like India, the overhead distribution lines traverse mostly ne... View full abstract»

• ### Refining structural texture synthesis approach

Publication Year: 2011, Page(s):184 - 189
Cited by:  Papers (1)
| | PDF (701 KB)

Structural textures are characterised by a repeating pattern called Texton and placement rule - that determines the nature of periodicity. Based on the periodicity, textures are classified as homogeneous - perfectly periodic - and weakly homogeneous - quasi-periodic. Both of these textures are assumed to be combination of structural information, illumination, that is, average brightness at diffe... View full abstract»

• ### Reversible and high-capacity data hiding in medical images

Publication Year: 2011, Page(s):190 - 197
Cited by:  Papers (7)
| | PDF (675 KB)

In this study, the authors introduce a highly efficient reversible data hiding system. It is based on dividing the image into tiles and shifting the histograms of each image tile between its minimum and maximum frequency. Data are then inserted at the pixel level with the largest frequency to maximise data hiding capacity. It exploits the special properties of medical images, where the histogram o...

• ### Metropolis monte carlo for tomographic reconstruction with prior smoothness information

Publication Year: 2011, Page(s):198 - 204
| | PDF (597 KB)

The Metropolis Monte Carlo algorithm was applied to produce tomographic reconstructions from scarce projection data supplemented by prior information about the smoothness of the object. The prior information is represented by means of local energy functions, which are added to the projection error. The proposed prior function is an extension of previous proposals of border filters, the novelty int... View full abstract»
