| * **Edge distance:** This parameter adjusts the distance (in pixels) between the edge detector. Increasing this value will help detect edges that are less distinct (fuzzier), but increasing will affect the barcode detection and decoding -- that is, it will increase the minimum barcode size. | * **Edge distance:** This parameter adjusts the distance (in pixels) between the edge detector.

| - | * **Maximum line compare:** This parameter can be thought of as maximum line velocity parameter for tracking lines between frames. For example, if a line moves from one side of the frame to the other side of the frame in one frame period (i.e. improbably large line velocity), it's probably not the same line, so this parameter is a sanity check for the tracking algorithm. Decreasing this value tells the algorithm to throw out more lines than before. Increasing the value tells the algorithm to be less restrictive regarding line velocity. | + | * **Maximum line compare:** This parameter can be thought of as maximum line velocity parameter for tracking lines between frames.

| * **Maximum merge distance:** This parameter determines how far the line tracking algorithm searches for nearby lines that might form an intersection. If the lines you are trying to track are wider, you should increase this parameter until the intersections formed with the wider lines are accurately detected. | * **Maximum merge distance:** This parameter determines how far the line tracking algorithm searches for nearby lines that might form an intersection.
