Moreover, the gray scale centroid algorithm is applied to obtain the subpixel location of both uncoded and coded targets. The initial matching of the uncoded target correspondences between an image pair is established according to similarity and compatibility, which are based on the ID correspondences of the coded targets. The outliers in the initial matching of the uncoded target are eliminated according to three rules to finally obtain the uncoded target correspondences. Practical examples show that the algorithm is rapid, robust and is of high precision and matching ratio.展开更多

The talents should qualified with strong professional ability as well as good psychological quality to adapt to the growing challenges, College students, a new generation of young people shouldering the historical mission and the important responsibility of the country, are under the great pressure from family, school and society. All of these will aggravate their negative psychological emotions with the formation of complicated personality, which not only go against the growth of young talent, but also drive hidden troubles to the stability and harmony of the social. Plunging into the students＇ life and deeply analyzing their psychological characteristics with timely manners of solving psychological problems will accelerate the ideological and political education and promote talents cultivation with more modem intellectuals for our country.展开更多

The functional properties and textural of crispy balls snacks （CBS） have been studied. The results showed that different protein types were significantly affected on functional and chemical properties of extrudate. The bulk density of CBS-SC was the lowest due to the highest expansion, while CBS-WPC retained the most water in the product, whereas, the maximum value of water solubility index was obtained in the CBS-CWP. Results also showed that protein digestibility value of extrudates had higher than non-extruded products. Color analysis of CBS-SC and CBS-SWS products had the highest AE values （P ≤ 0.05）, whereas CBS-SWS was statistically higher than CBS-SC in rank. Also, it was noticed that CBS-SWS had the highest value of browning index. The hardness of all extrudates products was desirable for expanded crispy where ranged from 17.3 N to 12.18 N. Generally, MPC and SC incorporated with cereal flour had acceptable quality characteristics and improved significantly the functional and texture properties of crispy balls products.展开更多
