The invention provides a method of evaluating the performance of a saliency data set. The method comprises the following steps: the ratio of a salient region to the whole image is calculated; the ratio of the number of salient regions connected with an image edge to all salient regions in the saliency data set is counted; RGB color feature differences between a salient region and the whole image are counted; and the performance score of each saliency data set from the first step to the third step is calculated. The data set can be counted from different angles to comprehensively evaluate the performance of the data set. Research and development on an objective and scientific saliency detection algorithm are facilitated, and design of an algorithm with not high robustness to cater to database deviations can be avoided.

The purpose of the present invention is to discover a method to obtain an antibody for hydrophobic peptides, which can be used for general purposes easily and with great reliability. This method for preparing an antigen is characterized in that hydrophobic peptides, which are not bonded to carrier proteins, are used as high molecular weight aggregates in an aqueous solution containing a nonionic surfactant.

The invention provides a rhesus monkey temporal lobe epilepsy kindling model. In the model, coriamyrtin with the subthreshold seizure dose of 0.5 ml / kg is applied in rhesus monkey, and the effect of 1ml of coriamyrtin injection is equivalent to that of 6.7g of raw material medicine Chinese coriaria leaf. The invention also provides a method for screening drugs for curing temporal lobe epilepsy. The method of the invention has the following advantages: the method is simple to establish and easy to operate and repeat, does not cause mechanical damage on the brain, has short seizure time, etc. The model of the invention resists the classical antiepileptic drug carbamazepine, thus the model can be used in the research on the pathogenesis of the temporal lobe epilepsy and the research on the development of new antiepileptic drugs.
