With the development of display technology, people are not satisfied with the normal two-dimensional display which is commonly used all over the world. People want the display technology to go much further, so that it can show more details of the real world by the way of three-dimensional.Compared with two-dimensional display, three-dimensional display can provide

As huge amount of geographical data especially 3D terrain data being produced, it has become a serious problem to visualize large-scale geographical scene. Nowadays, large-scale geographical scene visualization mainly acts as a platform for visualizing infrastructural geographical information, which faces many problems such as transmission of huge amount of data, large in-memory scene structure, resulting

Pulse compression is mainly used in modern radar system for distance detection and target recognition. Woodward perfect theoretically the idea of pulse compression, by proposing that the use of matched filter to compress the signal with large Time-Bandwidth Product would make the output more narrow. Thanks to the narrowness of output signal, the resolution of

The white matter occupies a large area in both human brain and thinking. For MRI(magnetic resonance image) is used to detect white matter lesions and identify early or mild whilt matter disease and mental illness, pattern recognition technology is used in this paper to indentify and segment the while matter area from MRI. Then the

Up to now, the testing of leather performance is mainly carried outby sensing, i.e. visual inspection and feeling. Try to overcoming thisshortcoming, a virtual instrument for measuring such leather performanceas compression, tension, and bending, has been developed, which consistsof the motion control system and the system for data sampling andprocessing.The hardware of the motion control
