The invention discloses a cloth defect detection method based on visual salience, which comprises the following steps: (1) collecting images; (2) processing brightness features; (3) processing direction features; (4) multi-channel superposition and normalizing processing; (5) Grayscale image processing; (6) Binarization processing; (7) Defect area judgment. Compared with the traditional cloth defect detection method, the present invention reduces the complexity of calculation, improves the recognition rate, and can accurately locate , and at the same time, it avoids false detections easily caused by the case where the gray value of the salient image of the detected cloth intact image is higher than the gray value of the intact part of the defect image, effectively reducing the interference of the background during the detection process, and reducing It prevents the misjudgment of the target area obtained by the adaptive threshold segmentation of the image of the intact cloth as the defective area.

A system and method for resilient communication services under multi-chassis APS protected routers, including one or more of the following: an add-drop multiplexer; a working chassis; a plurality of working lines of communication between the add-drop multiplexer and the working chassis; a protection chassis; a plurality of protection lines of communication between the add-drop multiplexer and the protection chassis; and a multi-chassis APS control link between the working chassis and the protection chassis, wherein a plurality of active entities in the working chassis having state information send their state information to parallel inactive entities in the protection chassis by way of the multi-chassis APS, the active entities send changed state information to parallel inactive entities through the multi-chassis APS control link upon a state change in the active entities, and the inactive entities that were down request current state information from the active entities through the multi-chassis APS control link when the inactive entities that were down come back up after being down.

The invention discloses a multi-objective optimization method for radar radiation source signal sorting based on a membrane system. First, the traditional clustering is transformed into a multi-objective optimization problem, and then the membrane calculation optimization theory is used as the main line, and the genetic algorithm is integrated into the membrane structure framework. Algorithms, computational intelligence and other intelligent information processing technologies are intersected, and the self-improvement ability of the algorithm and the calculation efficiency and fusion ability of the current typical intelligent algorithms are compared to verify the convergence accuracy and effectiveness of the membrane system, in order to obtain multiple data sets with different clusters. The Pareto frontier solution maintains the diversity and difference of sorting results, which is conducive to the accuracy of later sorting. Combined with the nature of radiation source signal sorting, the clustering validity index, feature evaluation index and other evaluation criteria related to sorting are constructed into corresponding problem models and multi-objective functions. For the intercepted unknown radar signals, the essence of unsupervised classification is in line with the classification requirements of radar emitter signals.
