Adaptive image interrogation for PIV: Application to compressible flows and interfaces

As an experimental tool, Particle Image Velocimetry has quickly superseded traditional point-wise measurements. The inherent image processing has become standardized though the performances are strongly dependent on user experience. Moreover, the arduously selected image interrogation parameters are applied uniformly throughout the image...

Telescience experiments using the prototype optical diagnostic instrument (PODI)

The breadboard called PODI (Prototype Optical Diagnostic Instrument) was developed following a study for a general facility for fluid experimental research on fluid physics in a space laboratory. PODI has been developed further for the study of telescience and image processing related to microgee instrumentation. The extended breadboard called...

Image data reduction with splines and segmentation with emphasis on earth observation

This report describes the results of a feasibility study on image data compression using spline approximation and image segmentation, with emphasis on earth observation applications. The main subjects dealt with, are: the data compression method, implementation aspects, the test software and test results. It appears that a reduction factor of 5...
