This 2-volume set constitutes the refereed proceedings of the 9th Iberian Conference on Pattern Recognition and Image Analysis, IbPRIA 2019, held in Madrid, Spain, in July 2019.

The 99 papers in these volumes were carefully reviewed and selected from 137 submissions. They are organized in topical sections named:

Part I: best ranked papers; machine learning; pattern recognition; image processing and representation.

Part II: biometrics; handwriting and document analysis; other applications.
