Multistep Wind Speed and Wind Power Prediction Based on a Predictive Deep Belief Network and an Optimized Random Forest

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
A variety of supervised learning methods using numerical weather prediction (NWP) data have been exploited for short‐term wind power forecasting (WPF). However, the NWP data may not be available enough due to its uncertainties on initial atmospheric conditions.

Texture Classification Using Scattering Statistical and Cooccurrence Features

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Texture classification is an important research topic in image processing. In 2012, scattering transform computed by iterating over successive wavelet transforms and modulus operators was introduced. This paper presents new approaches for texture features extraction using scattering transform. Scattering statistical features and scattering cooccurrence

The aceToolbox: low-level audiovisual feature extraction for retrieval and classification [PDF]

, 2005
In this paper we present an overview of a software platform that has been developed within the aceMedia project, termed the aceToolbox, that provides global and local lowlevel feature extraction from audio-visual content.

Normal Inverse Gaussian Model‐Based Image Denoising in the NSCT Domain

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
The objective of image denoising is to retain useful details while removing as much noise as possible to recover an original image from its noisy version. This paper proposes a novel normal inverse Gaussian (NIG) model‐based method that uses a Bayesian estimator to carry out image denoising in the nonsubsampled contourlet transform (NSCT) domain.

A HYBRID FACE RECOGNITION APPROACH USING LOCAL FUSION OF COMPLEX DUAL-TREE WAVELET COEFFICIENTS AND RIDGELET TRANSFORM [PDF]

ICTACT Journal on Image and Video Processing, 2011
In this paper, we propose novel face recognition method based on local appearance feature extraction using hybrid mode of local ridge- let and fused dual-tree complex wavelet transform (DT-CWT).

A multiresolution framework for local similarity based image denoising [PDF]

, 2012
In this paper, we present a generic framework for denoising of images corrupted with additive white Gaussian noise based on the idea of regional similarity.

Fingerprint Classification Combining Curvelet Transform and Gray‐Level Cooccurrence Matrix

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
Fingerprint classification is an important indexing scheme to reduce fingerprint matching time for a large database for efficient large‐scale identification. The abilities of Curvelet transform capturing directional edges of fingerprint images make the fingerprint suitable to be classified for higher classification accuracy.

Cosmological Non-Gaussian Signature Detection: Comparing Performance of Different Statistical Tests

EURASIP Journal on Advances in Signal Processing, 2005
Currently, it appears that the best method for non-Gaussianity detection in the cosmic microwave background (CMB) consists in calculating the kurtosis of the wavelet coefficients.

A Multiresolution Image Completion Algorithm for Compressing Digital Color Images

Journal of Applied Mathematics, Volume 2014, Issue 1, 2014., 2014
This paper introduces a new framework for image coding that uses image inpainting method. In the proposed algorithm, the input image is subjected to image analysis to remove some of the portions purposefully. At the same time, edges are extracted from the input image and they are passed to the decoder in the compressed manner.

A Note on Fractional Gabor Systems in L2(ℝ)

Journal of Function Spaces, Volume 2024, Issue 1, 2024.
In this article, fractional Gabor frames in L2(ℝ) are defined and studied. Also, a finite linear combination of fractional Gabor frames for L2(ℝ) is discussed. It is proved that under certain conditions, a finite linear combination of fractional Gabor frames is a fractional Gabor frame for L2(ℝ).
