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...

Image quality criteria with emphasis on criteria for remote sensing imagery

Image quality plays an important role on the various levels of image processing. However, until now it lacks a survey of methods for the evaluation of image quality. With a grant of the Netherlands Agency for Aerospace Programs (NIVR) a study was performed with respect to the quantification of image quality. Some results of this study are...
