Why Image Processing Is Used?

If an In-Sight job fails because of poor image quality, an Image function can help enhance the image so that the desired data is easier to extract. Some examples include:

• Reducing noise or changing the patterns of object connectivity for Blob analysis. For more information, see Blob.
• Converting spatial features into greyscale values so that statistics can be computed for Histogram analysis. For more information, see Histogram.
• Increasing the contrast of a 2D symbol against its background for 2D code reading. For more information, see ID.
• Minimizing confusing or unwanted spatial frequency characteristics from both the model and image pixel data, to improve the speed and reliability for PatFind template searching. For more information, see Pattern Match.
