Histogram
Note:
Since histograms are performed in the Verifier, the results will be save regardless of
whether the image was captured as a BMP or JPEG.
1. From the
Evaluation
window, click the
Histogram
button.
The current image is transferred into the histogram operation. This may take a
moment since all relevant pixels are being evaluated intensively.
2. When the
Histogram
window opens, you might need to expand the window and/or
adjust the scroll bars in order to bring the image into view.
3. To generate a histogram, click and drag your mouse pointer diagonally across the
symbol or a portion of it.
An area of interest box is a dashed blue line that can be selected and moved by
placing a cursor inside the box, or resized by clicking and dragging the handles.
Usage:
Useful in determining quality and contrast of symbols.
Definition:
A histogram is a graphical presentation of the numeric count of the occurrence
of each intensity (gray level) in an image. The horizontal axis is the values of
gray levels and the vertical axis is the number of pixels for each gray level.
