Segmentation > Find Lines

Finds lines in the Current Image using an algorithm based on searching within the image’s Hough transform.

1. Minimum Length

Rejects lines under a certain length.

2. Infinite Lines

Allows the detection of lines that proceed to infinity, in addition to line segments.

3. Detection Strength Settings

Threshold determines how strong a feature must be above background to be considered as a candidate line.

Sensitivity determines how eager the algorithm is to find lines within the image.


Line detection is relative to the strongest features in the image. Detection will be much more successful if items such as scale bars and information boxes are removed from the image first.
