checking feature
1.4) segmenting dot image and accounting dot area percent using Neural Network pattern recognition method, checking texture character based on Co-occurrence feature and fractal dimensional feature, and checking color correlation based on correlation coefficient of the image waiting for checking and standard image in the corresponding field.
7.Following Pesetsky(2000) and in accordance with the Attract Closest Principle(Chomsky,1995;Radford,2004),this article suggests that the in-situ wh-phrases occupying the highest structural positions before wh-movement undergo covert wh-feature movement by which wh-feature agreement checking takes place.
8.The transformation between the active and the passive pertains to many important syntactic principles, such as semantics in syntactic interpretation, the transformational relevance between D-structure and S-structure, syntactic realization of thematic roles and case assignments, feature-checking and subject-to-subject raising.
