Description: Bayesian Deblurring with Integrated Noise Estimation-Bayesian Deblurring with Integrated Noise Estimation
Conventional non-blind image deblurring algorithms
involve natural image priors and maximum a-posteriori
(MAP) estimation. As a consequence of MAP estimation,
separate pre-processing steps such as noise estimation and
training of the regularization parameter are necessary to
avoid user interaction. Moreover, MAP estimates involving
standard natural image priors have been found lacking in
terms of restoration performance. To address these issues
we introduce an integrated Bayesian framework that unifies
non-blind deblurring and noise estimation, thus freeing the
user of tediously pre-determining a noise level. A samplingbased
technique allows to integrate out the unknown noise
level and to perform deblurring using the Bayesian minimum
mean squared error estimate (MMSE), which requires
no regularization parameter and yields higher performance
than MAP estimates when combined with a learned highorder
image prior. A quan Platform: |

Description: Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.
