| Edge Detection-Diff. | Differentiation filtering. Produces continuous contours by highlighting
each pixel where an intensity variation occurs between itself and its
three upper left neighbors. | | Edge Detection-Laplacian | Laplacian filtering. Extracts the contour of objects and outlines
details. The Laplacian filter kernel has the following model: a d c b x b
c d a where a, b, c, and d are integers and x is greater than or equal
to the sum of the absolute values of the out | | Edge Detection-Prewitt | Prewitt filtering. A highpass filter that extracts the outer contours of objects. | | Edge Detection-Roberts | Roberts filter to detect edges. Outlines the contours that highlight
pixels where an intensity variation occurs along the diagonal axes. | | Edge Detection-Sobel | Sobel filter. A highpass filter that extracts the outer contours of objects. | | Embedded Vision Computer
| Another name for Embedded Vision Processor | | Embedded Vision Processor
| A
configuration of machine vision equipment where a camera is tethered to a
specialized, mini-computer (not a PC). Unlike the Smart Camera, the
computer power for processing images is external to the camera's
housing. | | Erode | Erosion reduces the brightness of pixels that are surrounded by neighbors with a lower intensity. | Exposure Time
| Exposure time is the amount of time
that the sensor is exposed to the light and thus accumulates charge.
This is the control that is used first (before gain and offset) to
adjust the camera. |
An innovative leader in machine
vision and laser integration deploying systems using advanced sensor
technologies servicing industrial automation, scientific and military
partners. |
