Roger S. Reiss is based in Leominster, Massachusetts. Pierre et Marie Curie researchers describe a new color-sensitive photodetector that consists of three buried junctions and is implemented with conventional BiCMOS or bipolar technology. Because each junction is sensitive to a specific range in the visible region, the device can specify colors without using optical filters. This reduces the surface area and cost of the color sensor. An industrial system, developed at the Univ.
Lighting is especially critical when the product being imaged is highly reflective.
The French system is composed of a structured lighting system and a new morphological local filter. The filter is designed around the knowledge of the shapes to be detected. Periodic microscreen design using direct binary search and training Purdue Univ. The algorithm has two main steps. In the first, screens are designed using direct binary search.
