In this talk, we will introduce some optimization problem in remote sensing data processing. The high dimensional characteristics of remote sensing data, especially hyperspectral data, will not only l...
Real-time convex optimization in signal processing
Convex optimization signal processing coefficient of algorithm filtering array design
font style='font-size:12px;'>
2015/8/7
Convex optimization has been used in signal processing for a long time, to choose coefficients for use in fast (linear) algorithms, such as in filter or array design; more recently, it has been used t...

2015/6/29
In the near future, there will be two more civil GPS signals in addition to the current one at the L1 frequency (1575.42 MHz). The second civil signal will be broadcast at the L2 frequency (1227.60 MH...
Rate-Distortion Optimization with Inter-iew Refreshment for Stereoscopic Video Coding over Error-Prone Networks
Rate-Distortion Optimization Inter-iew Refreshment Stereoscopic Video Coding
font style='font-size:12px;'>
2010/12/20
Stereoscopic video is a practical and important manner for 3-D video applications, and robust stereoscopic video transmission over error-prone networks has posed a technical challenge for stereoscopic...
Hierarchical Optimization of Visual Vocabulary for Effective and Transferable Retrieval
Hierarchical Optimization Visual Vocabulary Effective
font style='font-size:12px;'>
2010/12/20
Scalable image retrieval systems usually involve hierarchical quantization of local image descriptors, which produces a visual vocabulary for inverted indexing of images. Although hierarchical quantiz...

Joint Source-Channel Rate-Distortion Optimization for H.264 Video Coding Over Error-Prone Networks
Joint Source-Channel Rate-Distortion H.264 Video Coding
font style='font-size:12px;'>
2010/12/16
For a typical video distribution system, the video contents are first compressed and then stored in the local storage or transmitted to the end users through networks. While the
compressed videos are...
Drift Compensated Coding Optimization for Fast Bit-rate Reduction Transcoding
Drift Compensated Coding Fast Bit-rate Reduction Transcoding
font style='font-size:12px;'>
2010/12/17
Bit rate adaptation is one of the basic problems in universal multimedia access. Therefore, in many cases, there exists a strong requirement for a very fast transcoding implementation. Usually, open-l...
