LOCAL IMAGE PROCESSING

01 Input image

＋ Choose log image

PNG, JPEG or scanned log page

02 Binary & alignment

Black threshold 160

Rotation correction 0.0°

03 Axis calibration

Click each reference button, then click the actual chart ruling line in the image. Vertical lines establish X values; horizontal lines establish depth. Assign the real numerical value beside each selected line.

Depth references 3+ add QC checkpoints. The export uses piecewise-linear depth calibration between references; check the QC table for spacing inconsistencies.

0/4 reference lines placed. Click a button to begin.

Each click snaps to a nearby strong straight line (within 9 px). Hold Shift when clicking to use the exact pixel instead. Values can be edited afterward.

04 Remove ruling lines

Vertical line minimum 65 px

Horizontal line minimum 65 px

05 Extract wires

Select “Pick wire”, then click the desired trace. Each click adds another wire.

Click upper limit → lower limit → curve. For manual drawing, choose Draw by cursor. Set two limits, then press and drag inside the band. Both tools reset to Pick after one wire.

Use horizontal trace on nearly flat curve sections. It follows left/right pixels instead of depth rows.

Click two extracted segments in sequence, then confirm the join. The nearest endpoints connect into one ordered polyline. Each join produces one exported wire.

Join connection method

Image-guided: follow dark pixels in the cleaned image where possible. If no reliable path is found, the join is not performed; choose another method.

Break: click a wire to split it at that point. Erase: click two points on the same wire to discard the wrong section between them. A highlighted removal preview appears before the second click.

Work on group

Active data group name

Removes only wires in the selected group. Other groups and calibration remain unchanged. Confirmation required.

Auto-join new picks in the active group

Active: Gamma Ray · unlocked. Auto-join links nearest endpoints only within 80 pixels; long bridges require manual join. Lock a group when complete.

X axis scale

Gamma Ray uses a linear X axis. Each group remembers its own X references and scale. Depth references are shared.

Search radius 18 px

Vertex spacing 4 px

Depth and X require reference calibration. Pixel positions remain available without it.
