CARTOON Image abstraction using bilateral filtering. This function uses the bilateral filter to abstract an image following the method outlined in: Holger Winnemoller, Sven C. Olsen, and Bruce Gooch. Real-Time Video Abstraction. In Proceedings of ACM SIGGRAPH, 2006.

“Fast Tracking via Dense Spatio-Temporal Context Learning,” In ECCV 2014的源代码，效果非常好。(In this paper, we present a simple yet fast and robust algorithm which exploits the spatio-temporal context for visual tracking. Our approach formulates the spatio-temporal relationships between the object of interest and its local context based on a Bayesian framework, which models the statistical correlation between the low-level features (i.e., image intensity and position) from the target and its surrounding regions. The tracking problem is posed by computing a confidence map, and obtaining the best target location by maximizing an object location likelihood function. The Fast Fourier Transform is adopted for fast learning and detection in this work. Implemented in MATLAB without code optimization, the proposed tracker runs at 350 frames per second on an i7 machine. Extensive experimental results show that the proposed algorithm performs favorably against state-of-the-art methods in terms of efficiency, accuracy and robustness.)

通过此代码，实现OFDM调制。设定子载波个数为6，每个信道的比特数是4000(OFDM MODULATION)

说明：  matlab绘图，包括2D,3D等，很好用的！希望大家好好看一下(MATLAB)

频率采样法：使所设计的FIR数字滤波器的频率特性在某些离散频率点上的值准确地等于所需滤波器在这些频率点处的值，在其他频率处的特性则有较好的逼近。 (Frequency sampling method：Make the FIR digital filters designed by the frequency characteristic in some discrete frequency is equal to the value accurately in these frequency required filter in value, the characteristics of the other frequency place there is a better approximation. )
