Improved Adaptive Brovey as a New Method for Image Fusion
Hamid Reza Shahdoosti
An ideal fusion method preserves the Spectral information in fused image and adds spatial information to it with no spectral distortion. Among the existing fusion algorithms, the c…
Hyperspectral Images Classification Using Energy Profiles of Spatial and Spectral Features
Hamid Reza Shahdoosti
This paper proposes a spatial feature extraction method based on energy of the features for classification of the hyperspectral data. A proposed orthogonal filter set extracts spat…
Panchromatic Sharpening of Remote Sensing Images Using a Multi-scale Approach
Hamid Reza Shahdoosti
An ideal fusion method preserves the Spectral information in fused image and adds spatial information to it with no spectral distortion. Recently wavelet kalman filter method is pr…
A New Noise-Assistant LMS Algorithm for Preventing the Stalling Effect
Hamid Reza Shahdoosti
In this paper, we introduce a new algorithm to deal with the stalling effect in the LMS algorithm used in adaptive filters. We modify the update rule of the tap weight vectors by a…
A new ultrasound despeckling method through adaptive threshold
Hamid Reza Shahdoosti
An efficient despeckling method using a quantum-inspired adaptive threshold function is presented for reducing noise of ultrasound images. In the first step, the ultrasound image i…
Image denoising through bivariate shrinkage function in framelet domain
Hamid Reza Shahdoosti
Denoising of coefficients in a sparse domain (e.g. wavelet) has been researched extensively because of its simplicity and effectiveness. Literature mainly has focused on designing…
Robust non-local means filter for ultrasound image denoising
Hamid Reza Shahdoosti
This paper introduces a new approach to non-local means image denoising. Instead of using all pixels located in the search window for estimating the value of a pixel, we identify t…
A New Multifocus Image Fusion Method Using Contourlet Transform
Fatemeh Vakili Moghadam, Hamid Reza Shahdoosti
A new multifocus image fusion approach is presented in this paper. First the contourlet transform is used to decompose the source images into different components. Then, some salie…
Improving high-pass fusion method using wavelets
Hamid Reza Shahdoosti
In an appropriate image fusion method, spatial information of the panchromatic image is injected into the multispectral images such that the spectral information is not distorted.…
Using Complex Wavelet Transform and Bilateral Filtering for Image Denoising
Seyede Mahya Hazavei, Hamid Reza Shahdoosti
The bilateral filter is a useful nonlinear filter which without smoothing edges, it does spatial averaging. In the literature, the effectiveness of this method for image denoising…
A New Method for Removing the Moire' Pattern from Images
Seyede Mahya Hazavei, Hamid Reza Shahdoosti
During the last decades, denoising methods have attracted much attention of researchers. The conventional method for removing the Moire' pattern from images is using notch filters…
MS and PAN image fusion by combining Brovey and wavelet methods
Hamid Reza Shahdoosti
Among the existing fusion algorithms, the wavelet fusion method is the most frequently discussed one in recent publications because the wavelet approach preserves the spectral char…
