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...

The use of MEBAS in creating a simulation environment for compression and encryption

In order to get a better sight on the performance of compression and encryption algorithms under various conditions a simulation environment is needed. Within this simulation environment It must be possible to investigate the influence of code tables, channel characteristics and frame formats on the performance of the algorithms. In this report...

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...
