+# Molecule Detection YOLO in MolParser
+
+From paper: *MolParser: End-to-end Visual Recognition of Molecule Structures in the Wild*
+
+We provide several [ultralytics YOLO11]((https://github.com/ultralytics/ultralytics)) weights for molecule detection with different size & input resolution.
+
+## general molecule detection
+
+`moldet_yolo11[size]_640_general.pt`
+
+* 640x640 input resolution
+* support handwritten molecules
+* multiscale input (inputs can be single/multiple molecular cutouts, reaction or table cutouts, or single-page PDF images)
+
+<span style='color:gray'>For single-molecule input (used as a classification model), appropriate padding can be added to enhance the performance.</span>
+
+Result in private testing:
+| size | map50 | map50-95 |
+| ---- | ----- | -------- |
+|n | 0.9581 |0.85235 |
+|s|0.96522|0.87038 |
+|m|0.96857|0.87355 |
+|l|0.98912|0.90282 |
+
+
+## PDF molecule detection
+
+`202503 moldet_yolo11[size]_960_doc.pt`
+
+* 960x960 input resolution
+* single page PDF image input
+
