Triangulating the Effects of Interfixation in the Processing of German Compounds
The German language shows a high degree of compounding. The process is very productive in the language and compounds may be formed from the combination of four or more roots. In addition, German compounding also shows the presence of interfixes between constituents in about 35% of all compounds. We report on a compound composition experiment that investigates the role of these interfixes in on-line compound processing. The study reveals that interfixation carries with it a processing cost in German and that this processing cost is elevated in cases in which the interfix attaches to a truncated form of the initial compound constituent. Moreover, we find that response times are increased when initial compound constituents show inconsistent interfixation patterns across the language. These results support the view that German compounds are represented in terms of their constituents and that interfixation choices are made on-line.
After pointing out some essential difficulties in binocular stereo vision systems, we proposedthen a trinocular stereo vision method matching the feature primitives in 3-D space by use of pyramidalgraph.This method is based on the 3-D perspective projection geometry and needs no prior constraints or im-age similarities,so it can solve better the contradiction between the accuracy and matching difflculty. And theuse of pyramidal graph can speed up the matching process also. The experimental result for artirlcial imagesshows that the ratio Of false targets is almost zero,and the matching speed and accuracy is higher.
