For the complexities of production and the limitations and lacks of methods for cost estimation of customized productions, a method for cost estimation based on Case-Based Reasoning was put forward in the steel enterprises. The process flow of the steel productions was analyzed in order to determine every activity in manufacturing steel productions. The descriptive procedure for the cases and the...
Previous studies of depth and distance estimation with autostereoscopic 3D displays indicate the users do not necessarily exhibit better depth perception with such displays. Yet, users claim 3D displays provide higher immersiveness. As shapes of objects are often described by their angles, it is expected that angle perception would contribute to object recognition and scene understanding. However;...
This paper presents image-based finger pose measurement for hand user interface. The aim of this measurement technique is to make a better user interface enabling three dimensional operation by hand. The measurement technique uses stereo vision, and approximates the hand motion based on anatomical constraints. Distinctive feature of the measurement technique is usage of ring markers, which enable...
For various applications, such as object recognition or tracking and especially when the object is partly occluded or articulated as in human-machine-interaction scenarios, 3D information is crucial for the robustness of the application. Recently sensor had been developed that acquire distance information based Time-of-Flight (ToF) principle and for which distance errors based on different causes...
