The early detection, classification, and elimination of occlusion and specular highlights which occur frequently in real scenes are of utmost importance. However, most of vergence algorithms which have been proposed in recent years do not take into c

A two-layer neural network is proposed for modeling objects with freeform surfaces in computer graphics and computer vision. The parametric form describes not only geometric shapes and normal vectors but also texture and other optical features of arb

A modified multilevel median filter (MLMF) incorporating the fuzzy associative memory (FAM) system is proposed in this correspondence. The modified method-the adaptive fuzzy multilevel median filter (AFMMF)-overcomes some disadvantages common to most

The authors describe an exploratory vergence method which has the ability to detect occlusion and specular highlights using information that is inherent in the vergence process. They propose an active exploratory vergence method based on concurrent c

Recognition of partially occluded objects has long been a difficult task in the area of pattern recognition and computer vision. The presence of occlusions complicates the problem of image registration and hence the subsequent tasks of object recogni

A technique of constructing picture elements for a large screen display with improved color quality is described. Existing large screen displays generally make use of a cluster of lamps to form a single pixel. Such a pixel usually consists of four la
