Inspired by the boosting technique for detecting objects, this paper proposes a cascade structure with a resurrection mechanism to establish keypoint mappings on multispectral images. The cascade structure is composed of four steps by utilizing best bin first (BBF), color and intensity distribution of segment (CIDS), global information and the RANSAC(More)
Singer model is a whole statistic model, which considers all the possibility of the variance of the maneuvering target, and it is fit for a variety of situations and many kinds of maneuvers. So the probability of the occurrence of the concrete maneuver in each concrete tactics situation is small, which leads to the low accuracy of tracking. The(More)
Fault diagnosis of actuators in flight control system of an unmanned tandem helicopter has been studied in this paper. A support vector machine (SVM) observer is designed to parameter estimation and model compensation for its uncertainty, and then to fault detection. Further more, a fuzzy sample SVM (FS-SVM) based diagnostic tool is used to fault diagnosis(More)
In the multi-sensor data fusion system, the data acquired by each sensor which will be fused should be at the same time level so that the correct state can be worked out. But actually the time error exists for the delay of the data transmission and the disaccord of the sampling cycles of the sensors. The time error has great effect on the measured distance(More)
Hematopoietic stem cells (HSCs) replenish all types of blood cells. It is debating whether HSCs in adults solely originate from the aorta-gonad-mesonephros (AGM) region, more specifically, the dorsal aorta, during embryogenesis. Here, we report that somite hematopoiesis, a previously unwitnessed hematopoiesis, can generate definitive HSCs (dHSCs) in(More)
