A method and apparatus for two-stage packet classification, the two-stage packet classification scheme including a first stage and a second stage. In the first classification stage, a packet is classified on the basis of the packet's network path. In the second stage of classification, the packet is classified on the basis of one or more transport (or other) fields of the packet. Also disclosed are embodiments of most specific filter matching and transport level sharing, and either one or both of these techniques may be implemented in the two-stage classification method.

For the segment class designation the temporal position of segments in two candidate segment classes is used for the stanza / refrain selection by means of a segment class designation means, wherein the highest-order segment class is designated as refrain segment class only when it has a segment following temporally later in the audio piece than the latest segment of the other candidate segment class. With this, segment class labeling with a low error rate is achieved, which can at the same time be implemented with easy effort and is further predestined for automated flow.

A two-dimension code local recognition method and the device based on the secondary classification. The device includes: the coding unit, the module local unit, the firstly secondary classification unit and the secondly secondary classification. The firstly secondary classification unit makes the whole figure with the two-dimension code secondary classification firstly and output the secondary figure to the module local unit; the module local unit locates the position in the figure of every module in the two-dimension code to get the grey value of every module, then to classify secondarily to get the code number of every module and output to the coding unit; the coding unit can get the information stored in the two-dimension code according to the code number. The invention can improve the accurate of reading the two-dimension code.

With little efforts, to estimate the appropriateness of automatic defect classification, and to make classification criteria settable with a guarantee for the better classification performance, defects unknown with their classification classes are classified based on two different classification criteria. Also, defects differed in classification results are collected, and each thereto, a defect classification class is provided by using a manual. Then, the defects provided with the classification classes are divided into two types of groups: one is a setting group for the classification criteria; and the other is an evaluation group. Based on the classification criteria that is so set as to classify the defects included in the setting group with the maximum performance, the classification performance of a case where classification is applied to defects included in the evaluation group is calculated, and the appropriateness of thus set classification criteria is evaluated.

The invention discloses a recycling method of metallic iron in mixed steel slag of weakly magnetic iron and magnetic iron. The recycling method comprises the following steps of adopting two-stage crushing, carrying out rough grinding with a rod mill so as to avoid over crushing of materials and ensure that chunk metallic steel slag is effectively ground, and carrying out stage classification to obtain a chunk steel slag metallic iron finished product; sieving slurry, and carrying out separation to obtain a qualified metallic iron finished product with a washbox; discarding large amounts of tailings subjected to the washbox through the technological procedures of magnetic separation, fine grinding and secondary magnetic separation so as to improve the grade of the material iron product, and carrying out reselecting to obtain an iron ore concentrate finished product with a spiral chute; and recycling the generated tailings. According to the processing method, steel slag metallic iron products of different stages are obtained through fully using the characteristics that the materials are different in particle size, specific gravity, magnetism, and the like; the method is simple in technology, easy to operate, low in cost, high in metal recovery rate and friendly to production environment; chemical substances are avoided in the whole production technology, and no harmful impurity is generated; and the processing method is suitable for large scale industrial production and wide in application prospect.
