Camera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy

M. Karami; A. Moosavie nia; M. Ehsanian

Volume 8, Issue 1 , January 2020, Pages 1-12


  In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity ...  Read More

An Evolutionary Multi-objective Discretization based on Normalized Cut

M. Hajizadeh-Tahan; M. Ghasemzadeh

Volume 8, Issue 1 , January 2020, Pages 25-37


  Learning models and related results depend on the quality of the input data. If raw data is not properly cleaned and structured, the results are tending to be incorrect. Therefore, discretization as one of the preprocessing techniques plays an important role in learning processes. The most important ...  Read More

Interval Type-II Fuzzy H∞ Frequency Control for an Island Microgrid

F. Sabahi

Volume 8, Issue 1 , January 2020, Pages 39-48


  Frequency control is one of the key parts for the arrangement of the performance of a microgrid (MG) system. Theoretically, model-based controllers may be the ideal control mechanisms; however, they are highly sensitive to model uncertainties and have difficulty with preserving robustness. The presence ...  Read More

Improvement of Rule Generation Methods for Fuzzy Controller

N. Mohammadkarimi; V. Derhami

Volume 8, Issue 1 , January 2020, Pages 49-54


  This paper proposes fuzzy modeling using obtained data. Fuzzy system is known as knowledge-based or rule-bases system. The most important part of fuzzy system is rule-base. One of problems of generation of fuzzy rule with training data is inconsistence data. Existence of inconsistence and uncertain states ...  Read More

Segmentation Assisted Object Distinction for Direct Volume Rendering

A. Azimzadeh Irani; R. Pourgholi

Volume 8, Issue 1 , January 2020, Pages 67-82


  Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently ...  Read More

Nonparametric Spectral-Spatial Anomaly Detection

M. Imani

Volume 8, Issue 1 , January 2020, Pages 95-103


  Due to abundant spectral information contained in the hyperspectral images, they are suitable data for anomalous targets detection. The use of spatial features in addition to spectral ones can improve the anomaly detection performance. An anomaly detector, called nonparametric spectral-spatial detector ...  Read More

Capturing Outlines of Planar Generic Images by Simultaneous Curve Fitting and Sub-division

A.R. Ebrahimi; Gh. Barid Loghmani; M. Sarfraz

Volume 8, Issue 1 , January 2020, Pages 105-118


  In this paper, a new technique has been designed to capture the outline of 2D shapes using cubic B´ezier curves. The proposed technique avoids the traditional method of optimizing the global squared fitting error and emphasizes the local control of data points. A maximum error has been determined ...  Read More

Salt and Pepper Noise Removal using Pixon-based Segmentation and Adaptive Median Filter

S. Asadi Amiri

Volume 8, Issue 1 , January 2020, Pages 119-126


  Removing salt and pepper noise is an active research area in image processing. In this paper, a two-phase method is proposed for removing salt and pepper noise while preserving edges and fine details. In the first phase, noise candidate pixels are detected which are likely to be contaminated by noise. ...  Read More
