Abstract: A Tracking Dip Estimator software including a novel Multi-Sine Tracking Software is adapted to be stored in a computer system memory for instructing a processor to produce a “first output” including a plurality of tracks in response to input borehole image data, and a “second output” including a plurality of “dip data” d in response to the plurality of tracks, the Tracking Dip Estimator software generating the “first output” and “second output” by: (1) pre-processing the input borehole image data with a Detector to output a plurality of image edge elements called “reports”, (2) using the reports as input to a Multi-Sine Tracking software that recursively develops a “first output” including a plurality of tracks, or a plurality of connected sets of track points, lying along sinusoidal dip events in the input borehole image data; the Multi-Sine Tracking software has embedded mathematical models for sinusoidal dip events, (3)
