Description: 压缩传感是一个从2006年左右开始兴起的研究领域，它关注于如何采样信号，也就是信号的采样方式或者压缩方式。通过设计一种特殊的采样方案，可以使得采样频率降低为信号的“信息率”，而不是传统的奈奎斯特采样率，于是，实际的采样率可以大大低于奈奎斯特频率，却只损失很少的信息量，依然保持了充足的信息量足以恢复出采样前的原始信号。这个研究思想挑战了奈奎斯特频率的理论极限，会对整个信号处理领域产生极其深远的影响，同时，信号处理的许多应用领域也会随之发生根本性的发展和变化。
-Compressive sensing (CS) is an emerging fi eld based on the revelation that a small
collection of linear projections of a sparse signal contains enough information for sta-
ble, sub-Nyquist signal acquisition. When a statistical characterization of the signal
is available, Bayesian inference can complement conventional CS methods based on
linear programming or greedy algorithms. We perform approximate Bayesian infer-
ence using belief propagation (BP) decoding, which represents the CS encoding matrix
as a graphical model. Fast encoding and decoding is provided using sparse encoding
matrices, which also improve BP convergence by reducing the presence of loops in
the graph. To decode a length-N signal containing K large coeffi cients, our CS-BP
decoding algorithm uses O(K log(N)) measurements and O(N log2
(N)) computation.
Finally, sparse encoding matrices and the CS-BP decoding algorithm can be modifi ed
to support a variety of signal models and measurement noi

Description: 本文提出一种基于边缘自适应小波变换的多尺度图像修复算法，对非纹理图像有比较好的修复效
果。边缘自适应小波变换的基本思想是，先检测出图像的主要边缘，这些边缘把图像分割成几个平滑区，然后
对图像进行不跨越边缘的小波分解，即在各平滑区内部进行小波变换，得到图像的多尺度表示，并且同时计算
边缘的多尺度表示。这样的小波分解使高频信息基本都集中在边缘上，而高频系数则非常稀疏，而且都接近
于零。在此基础上进行图像修复，就只需要对低频部分与边缘图像进行修复，然后重构得到修复图像即可。
经过小波分解，低频部分破损区域大大缩小，用比较简单的插值方法就可进行修复，大大降低了计算量。对边-Abstract：A fast inpainting algorithm based on edge—adaptive wavelet transform are in—

Description: We consider the problem of tracking mu ltiple maneuvering targets in the presence of clutter u sing switch ing multiple target motion mo d els. A n ovel sub optimal fixed-lag
smo othing algorithm is develop ed by applying the b asic interacting multiple mo d el (IMM) approach and joint probabilistic d ata asso ciation (JPDA) technique to a state augmented system. But unlike the standard single scan JPDA
approach, we exploit a multiscan JPDA (Mscan-JPDA) approach to solve the d ata asso ciation problem. The algorithm is illustrated via a simulation example.
