RESOLUTION ENHANCEMENT ALGORITHM FOR SPACEBORN SAR BASED ON HANNING FUNCTION WEIGHTED SIDELOBE SUPPRESSION
SAR image Sidelobe suppression Hunning function
2018/5/14
Resolution and sidelobe are mutual restrict for SAR image. Usually sidelobe suppression is based on resolution reduction. This paper provide a method for resolution enchancement using sidelobe opposit...
MICROPHONE ARRAY SPEECH ENHANCEMENT BY BAYESIAN ESTIMATION OF SPECTRAL AMPLITUDE AND PHASE
MICROPHONE ARRAY SPEECH ENHANCEMENT BAYESIAN ESTIMATION SPECTRAL AMPLITUDE AND PHASE
2015/9/29
Microphone arrays provide new opportunities for noise reduction and speech enhancement. This paper presents anovel decomposition of the estimation problems for short-time spectral amplitude (STSA), lo...
MULTI-CHANNEL PSYCHOACOUSTICALLY MOTIVATED SPEECH ENHANCEMENT
MULTI-CHANNEL PSYCHOACOUSTICALLY SPEECH ENHANCEMENT
2015/9/29
Multichannel techniques offer advantages in noise reduction and overall output signal quality when compared to the well studied mono approaches. In this paper we present an original multichannel psych...
BAYESIAN SINGLE CHANNEL SPEECH ENHANCEMENT EXPLOITING SPARSENESS IN THE ICA DOMAIN
BAYESIAN SINGLE CHANNEL SPEECH ENHANCEMENT EXPLOITING SPARSENESS ICA DOMAIN
2015/9/29
We propose a Bayesian single channel speech enhancement algorithm to exploit speech sparseness in the independent component analysis (ICA) domain. While recent literature considers the idea of denoisi...
PERFORMANCE ASSESSMENT METHOD FOR SPEECH ENHANCEMENT SYSTEMS
PERFORMANCE ASSESSMENT METHOD SPEECH ENHANCEMENT SYSTEMS
2015/9/29
A new method to assess noise reduction algorithms with respect to their ability to enhance the perceived quality of speech is presented. Such algorithms consist of both single-microphone systems and m...
BIOMIXING BY CHEMOTAXIS AND ENHANCEMENT OF BIOLOGICAL REACTIONS
CHEMOTAXIS ENHANCEMENT BIOLOGICAL REACTIONS
2015/7/14
Many processes in biology involve both reactions and chemotaxis. However, to the best of our knowledge, the question of interaction between chemotaxis and reactions has not yet been addressed either a...
Nonlocality-induced front interaction enhancement
nonlocal coupling spatial dynamics quantitative Nonlocality-induced
2011/7/6
We demonstrate that nonlocal coupling strongly influences the dynamics of fronts connecting
two equivalent states. In two prototype models we observe a large amplification in the interaction
strengt...
PDEs-based method for image enhancement
Complex diffusion Denoising Partial differential equation
2010/9/10
Removing noise from data is often the first step in data analysis. De-noising technique should not be only reduce the noise, but do so without blurring or changing the location of the edges. Many appr...
