The development of Doppler ultrasound allows us to convert the distribution of reflective ultrasound energy into colored blood flow imaging. The Doppler spectrogram also reveals the change of flow velocity over time when specifying an observation window inside the vessel wall. With the information doctors can visually search for abnormalities in blood vessels or valves from irregular patterns in the...
Video-SAR combines SAR imaging and video techniques together, enabling continuous surveillance of a specific area, which is a new developing microwave detection technology. Several airborne Video-SAR achievements have been published; however, less attention has been paid to the moving targets in the Video-SAR as well as spaceborne platforms. In this paper, the continuous observation problem of spaceborne...
The Shoot Apical Meristem (SAM) is made of stem cells that are responsible for all above ground plant structures. Differentiating cells in the development of SAM form primordia. Primordia develop to become various plant organs. Understanding the growth dynamics of primordia is critical to understanding the developmental dynamics of the entire SAM. We present a method for performing quantitative analysis...
In this paper, we present a local graph matching based method for tracking cells and cell divisions in noisy images. We work with plant cells, where the cells are tightly clustered in space and computing correspondences across time can be very challenging. The local graph matching method is able to track the cells and cell divisions even when significant portions of the images are corrupted due to...
Based on the principle of infrared radiation, the formulas of the real temperature calculation of a target surface under various conditions were derived. Thereby we obtain the real difference in temperature between two points, so that formulate expressions of the relative temperature difference. And introduce some application of infrared imaging technique in the test of the fault of low-voltage apparatus.
The morphological measurement simulation system based on FM-CW is built and tested. The result of 10 km imaging experiments shows that the range accuracy can reach 1.00 m and that the system has achieved the design goal.
In this paper, we present a local graph matching based method for tracking cells and cell divisions. This will allow us to estimate the lineages of the cells in a 4D spatio-temporal image stack obtained using fluorescence imaging techniques. We work with plant cells, where the cells are tightly clustered in space and computing correspondences in space and time can be very challenging. The local graph...
