Abstract: The image edge detection was based on wavelet transformation, the image’s smooth degree and scale increase are in direct proportion: the high frequency was restrained when scale aggrandized, the signal/noise ratio of the image output was increased, the image edge smoothness became rough, and the edge location precision was reduce. Contrarily, edge location precision was improved. The detect precision is ensured before the selection of wavelet function, so the noise of original image is restrained by the large size-filter. At the same time, the small size-filter was adopted to locate the image edge precisely. So, a quadric B-spline wavelet was constructed according to the general rules of wavelet mother function for edge detection, and the method of adaptive thresholds edge detection was used to detect the image edge.

实时系统中的优先级继承

（中国兵器工业第五八研究所 军品部，四川 绵阳 621000）

摘要：优先级继承协议可解决实时系统中优先级反转。多数支持优先级继承的嵌入式实时操作系统，要求释放资源的顺序与获得资源的顺序相反。当允许资源按任何顺序释放时，若一个任务拥有多个共享资源，优先级被提升多次。释放资源时，任务优先级须调节适当，否则将导致非受限的优先级反转。解决优先级反转的最好方法是通过详细的系统设计，以避免优先级反转。

Priority Inheritance Protocol in Real-Time System

LI Pan-feng, ZHOU Yong

(Dept. of Military Products, No.58 Institute of China Ordnance Industries, Mianyang 621000, China)

Abstract: The priority inversion in real-time system is solved with priority inheritance protocol. Most of the embedded real-time operation systems supported the priority inheritance require that the order of releasing resource is mutually inversed with the order of acquiring resource. When the resources are allowed to release in any order, if a task has multiple sharing resources, priority of task is hoisted many times. When the resource was released, the priority of task was adjusted to the appropriate level. Otherwise, unbounded priority inversion was brought on. The best solution to priority inversion is that the priority inversion is avoided by precise design of system.
