  3. AMI group people • Aleman Miguel (Permanent position at ULPGC) • Alvarez Luis (Permanent position at ULPGC) • Castaño Carlos (Engineer, financed by FLUID project since october 1, 2005) • García Miguel (Engineer, financed by FLUID project since november 1, 2005) • González Esther (Permanent position at ULPGC) • Krissian Karl (PostDoc position, financed by FLUID project since december, 2005 • Mazorra Luis (Permanent position at ULPGC) • Salgado Agustín (University grant holder, financed by the ULPGC) • Sánchez Javier (Permanent position at ULPGC) FLUID Specific Targeted Research Project - Las Palmas Meeting

  4. AMI group background • Mathematical Analysis • Multiscale Analysis • Partial differential equations • Nonlinear filtering • Optic flow estimation techniques • Shape Analysis • 3D geometry reconstruction from 2 or multiple views • No previous experience in fluid image sequence FLUID Specific Targeted Research Project - Las Palmas Meeting

  5. WP 2: Physical models and early image processing. Activities • Analysis of optic flow estimation techniques • Multiscale approach using structure tensor information at different scales • PDE based approach • Correlation methods • Report 1: Optic flow estimation in fluid images I • Report 2: A Methodology to Compare Optic Flow Estimation methods FLUID Specific Targeted Research Project - Las Palmas Meeting

  6. WP 2: Physical models and early image processing. Future plans • To continuous to work on 2D multiscale analysis • To combine correlation based sparse methods and dense variational approach FLUID Specific Targeted Research Project - Las Palmas Meeting

  7. WP 3: 2D Fluid motion analysis. Activities (Questions) • Fluid mechanics evolution models. PDE equations ? • Navier-Stokes ? Parameters? • Vorticity equation ? • Pressure equation ? • Coriolis force ? • Hodge decomposition ? • Can we hope (by adding constraints) to solve PDE fluid mechanics evolution models in a 3D neighbourhood of a 2D layer where we have a motion estimation ? FLUID Specific Targeted Research Project - Las Palmas Meeting

  8. WP 3: 2D Fluid motion analysis. Vortex models I • Fluid mechanics evolution models. Vortex models FLUID Specific Targeted Research Project - Las Palmas Meeting

  9. WP 3: 2D Fluid motion analysis. Vortex models II • Fluid mechanics evolution models. Vortex models FLUID Specific Targeted Research Project - Las Palmas Meeting

  10. WP 4: 3D Fluid motion estimation. Satellite sequences (layer segmentation) • Compute 2D flow estimation. • Transform of flow information from pixels to physical measures (motion in Km) • Compute the height of each point using infrared temperature intensity value. • Compute a segmentation of the infrared temperature channel • Implementation of a 3D visualization tool for the layers • Tracking regions using a motion model • A robust tracking method could deal with layer occlusions. FLUID Specific Targeted Research Project - Las Palmas Meeting

  11. WP 4: 3D Fluid motion estimation. PIV stereoscopic motion estimation • Calibration. Alignment between the light sheet and the calibration plate • PIV 3D motion estimation using 2 or multiple views. FLUID Specific Targeted Research Project - Las Palmas Meeting

  12. Project risk analysis • We need to design tractable applied physical models. The interplay between 2D image measurements and 3D dynamical system is perhaps too complex. • We need to design a multi-layer coupling model (too complex). • Computer vision groups of the project need to strongly interact with the other partners. • We need to define clearly a way to share results and a validation strategy. • We need to identify specific tasks in the project where different partners work together. • We need to convince Bruxelles people that everything is fine.
