Aiming at buildup of the pragmatic model of crane, a three-dimensional dynamical equation as well as its concise dynamical equation under the circumstance of the cable With the fixed length was push forward in this paper. A self-adaptive fuzzy PID controller proposed was fully able to realize the precise positioning control horizontally. In the meantime, a(More)
The ROI regions in JPEG2000 coding system mostly are defined artificially but it will decrease working efficiency a lot. This paper proposed a new fast face detection method based on AdaBoost and skin color detection, and introduced it into the JPEG2000 coding system. The experiments show that the false alarm rate of the human face detection is obviously(More)
