In: Measurement Science and Technology, 34(2), 021001, Feb. 20230957-0233https://hdl.handle.net/10016/36131Advancements in machine-learning (ML) techniques are driving a paradigm shift in image processing. Flow diagnostics with optical techniques is not an exception. Considering the existing and foreseeable disruptive developments in flow field measurement techniques, we elaborate this perspective, particularly focused to the field of particle image velocimetry. The driving forces for the advancements in ML methods for flow field measurements in recent years are reviewed in terms of image preprocessing, data treatment and conditioning. Finally, possible routes for further developments are highlighted.19eng© 2022 IOP Publishing LtdAtribución-NoComercial-SinDerivadas 3.0 EspañaMachine learningFlow-field measurementsImage processingParticle image velocimetryresearch articleIngeniería Mecánicahttps://doi.org/10.1088/1361-6501/ac9991open access12, 02100119Measurement Science and Technology34AR/0000031486
