We present a software tool for the analysis of 3D-line shaped objects in a 3D grey valued image. We discuss the extraction of the object from the image, the measurement of its shape features and its display.

Software reuse provides several advantages, e.g., increased productivity and software quality, decreased development time and costs. Installing reuse programs requires up-front investments. Empirical data showing that a potential for software reuse exists in a certain environment will help managers to decide on such investments. In order to determine the potential productivity gain it is necess...

This paper reports new results regarding the usefulness of colour measurements in flotation process. Colour measurements coming simultaneously from RGB-camera and a spectrophotometer (and from the same measurement point) are compared. The measured variables are used to construct a partial least squares (PLS) model and a multilinear regression (MLR) model for the prediction of the zinc content i...

The performance of scanning electron microscope can be defined in terms of parameters such as the spatial resolution, and the signal to noise ratio of the image. Knowledge of these quantities is important in verifying that an instrument meets its specification, and subsequently for tracking and optimizing its performance during use. Analytical methods based on the power spectrum (2-D Fourier tr...

The impedance characteristics of household-appliances and power-line channels in the Japanese environment are measured in the high-frequency band, i.e., from 70to 35MHz. The transfer function of the channels is also measured and these results are shown. The powerline channel can be treated as a distributed constant circuit at the high frequency band. In this paper, the distributed constants of ...

This report describes activity at a workshop on New Measurement Technology for Polymer Processing which was held at the National Institute of Standards and Technology on December 3-4,1990. The workshop was attended by 19 industry scientists and engineers from polymer processing and instrumentation manufacturing companies. The objective was to seek industry responses to the question: what in-lin...

The line-structured light vision sensor has been used widely in industrial vision measuring fields due to its simple structure, small volume, light weight, low cost, convenient calibration, and high accuracy of measurement. To locate the reference sphere precisely with line-structured light vision sensor, a mathematical model based on the measuring principle of line-structured light vision sens...
