Vision Basics - Mode Sample Vision Matrix Binary Processing When the software processes image data in binary mode, each value in the matrix is com- pared with the threshold value. All the pixels with a value above the threshold value are con- sidered white and all the pixels below this value are considered black. In binary mode, edges of objects within the field of view are found by looking for a change from a white section of pixels to a dark section of pixels. Binary Representation of Sample Matrix shows how the sys- tem would process the data from a greyscale image into a binary image if the threshold were set to 34. The threshold, when used, is set from within a vision tool.
There are several vision tools that allow you to set a binary threshold specifically for that tool. These tools create a new thresholded image within the area of the tool and perform their work based on this new data. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 308
