  We report an algorithm designed to perform computer-automated tuning of a
single quantum dot with a charge sensor. The algorithm performs an adaptive
measurement sequence of sub-sized stability diagrams until the single-electron
regime is identified and reached. For each measurement, the signal processing
module removes the physical background of the charge sensor to generate a
binary image of charge transitions. Then, the image analysis module identifies
the position and number of lines using two line detection schemes that are
robust to noise and missing data.
