Improvement of images by pixel realignment

Centre National d'Etudes Spatiales CNES - 10/17/2016


Correction of pixel alignment faults by means of advanced image manipulation. The images captured by an alternate acquisition device, such as anti-glare systems, may be subject to defects, particularly pixel shifting. The image manipulation proposed applies a correcting lter to the original image.


Improving image quality - Increased image quality - The bene ts of alternate acquisition are retained, such as anti-glare - Correction of outline aliasing Systematic correction of a series of similar images - Possibility of de ning systematic correction parameters


Optimisation of existing systems - Initially designed for sweep acquisition systems - Adaptable to other acquisition means causing pixel shifting - Based on a single pre-sampling
