saimiriA photo becomes a geometric logomark
Saimiri draws the construction grid of circles and lines over the subject, then keeps the regions a designer would keep. The result is a clean SVG made only of lines and arcs.
Across the evaluation photos: median IoU 0.929 against the subject, with 17 primitives.
From photo to logo
One step uses AI, once per image. The rest is classical geometry.
- Segment the subjectA small model (U²-Netp) cuts the subject out of the photo.
- Fit lines and arcsThe outline is split into the fewest lines and circular arcs that follow it.
- Build the gridArcs become full circles and lines get overshoot: the designer's construction grid.
- Snap to the gridParallels, equal radii and tangencies are aligned, as long as the shape stays faithful.
- Pick the regionsThe grid cuts the image into faces; the ones inside the subject are kept.
- ExportA logo SVG and a construction sheet showing the grid behind it.
Examples
Each row is one photo: the subject, the construction grid with the final shape on top, and the logo alone. Across the 8 shown here the pipeline keeps the outline closely enough to be recognizable with few primitives; the median over the full evaluation set is an IoU of 0.929 with 17 primitives.
