Change detection is a hot issue and is of great significance in remote sensing. The logarithm operation is a valid way to reduce the influence of multiplicative noise in the Synthetic Aperture Radar (SAR) image. However, changed areas with high gray level values will be weakened due to the nature of the logarithmic function. In this paper, a SAR image change detection framework based on visual attention...
Chlorophyll content plays an important role in the growth of crop. Chlorophyll content of crop not only shows the situation of crop growth but also has important significance in disease diagnosis. By using hyperspectral imaging technology, chlorophyll content can be diagnosed non-destructively. Before the correlation analysis, the experiment gets the SPAD values and vegetation indexes. The result...
To assure the construction and operation security of the smart grid, it is necessary to assess the real-time operation reliability of the power cables which work in power tunnels by using on-line monitoring data. An online assessment system, which presents the important operating characteristics of the power cables, has been built up based on the following data: some preventive experiments results...
Motion information occupies a considerable portion of the bit stream generated by the state-of-the-art video codecs. As a sequence, reducing bits on motion information can improve the overall performance of video compression. Various competition based motion vector coding (MVC) schemes were proposed for this goal. In this paper we propose a region based motion vector prediction (RMVP) algorithm to...
At present, each industry has its own database system. Yet, the overall performance of the business systems is falling, with the increase of running time and the rapid growth of the amount of data. Data rapid finding program was designed in this paper, table partition and index partition technology were used in large oracle table, and fast data retrieval was completed.
An integrated beam synthesis algorithm is presented to optimize the multiple beams of variable look-angle SAR antenna. With an iterative solution scheme of improved projection matrix algorithm, the amplitude excitations (common to all beams) and the phase of such excitations (corresponding to each radiated beam) are determined simultaneously. Antenna beams are controlled by phase only in SAR system...
