Description: 计算SENSE重建图像中的g-factor,这是并行磁共振成像SENSE算法的关键一步-G-factor is the metric to quantify the amplificaiton of noise power in reconstructing SENSE accelerated image. The detail was presented in Pruessmann s 1999 Magn. Reson. Med. paper. In theory, g-factor is the pixel-by-pixel ratio of the image variance between the SENSE reconstructed image and un-accelerated image. And g-factor depends on: (1) the k-space data trajectory (2) coil sensitivit profiles (3) noise covariance matrix of the array coil

Description: A new approach toward target representation and localization, the central component in visual tracking of nonrigid objects,
is proposed. The feature histogram-based target representations are regularized by spatial masking with an isotropic kernel. The
masking induces spatially-smooth similarity functions suitable for gradient-based optimization, hence, the target localization problem
can be formulated using the basin of attraction of the local maxima. We employ a metric derived from the Bhattacharyya coefficient as
similarity measure, and use the mean shift procedure to perform the optimization. In the presented tracking examples, the new method
successfully coped with camera motion, partial occlusions, clutter, and target scale variations. Integration with motion filters and data
association techniques is also discussed. We describe only a few of the potential applications: exploitation of background information,
Kalman tracking using motion models, and face tracking.

Description:
Motion detection results
If you double-click the Switch block so that the signal is connected to the SAD side, the Video Viewer block displays the SAD values, which represent the absolute value of the difference between the current and previous image. When these SAD values exceed a threshold value, the demo highlights the quadrant in red.
Note that the difference image itself may be viewed, in place of the original intensity image, along with the red motion highlighting, which indicates how the SAD metric works.

Description: 本文提
出了基于功率预留的准入控制策略。首先介绍一种资源分配算法，该算法将可用信
道完全分配从而实现基站发射功率最小化。在此基础上，分别为小区间切换用户和
小区内切换用户设计预留策略，并根据系统的业务载荷自适应地调整功率预留量，
从而实现GOS的最优化。
-there exists a fundamental tradeoff between bandwidth and power. In this thesis, we
propose a novel admission control scheme based on power reservation. Foremost, we
introduce a joint subchannel and power allocation algorithm for WiMAX system, which
minimizes the overall downlink transmit power by utilizing all available subchannels.
Based on this, we propose two power reservation schemes for inter-cell handoff calls and
intra-cell handoff calls, respectively. The amount of reserved power is determined in an
adaptive manner for optimizing the metric of Grade of Service(GoS).
