Beeldcorrectie

Beeldcorrectie is the process of adjusting an image to improve its accuracy or to achieve a desired presentation. It encompasses both geometric and photometric corrections applied to digital images and, in some contexts, to scans and prints.

In photography and videography, beeldcorrectie includes white balance, exposure or brightness correction, contrast and color adjustments, gamma correction, noise reduction, sharpening, and correction of lens-induced distortions or perspective. In scanning and printing, it covers color management, calibration with ICC profiles, tonal reproduction, and compensation for scanner or printer limitations.

In medical imaging, beeldcorrectie refers to correcting artifacts and distortions in images such as CT, MRI or PET to improve interpretability and diagnostic accuracy. Common techniques include motion correction, geometric distortion correction in certain sequences, field inhomogeneity correction, and denoising.

In surveillance and remote sensing, corrections address atmospheric effects, sensor bias, radiometric calibration, and geometric rectification to ensure comparability across time and platforms.

Technologies used include algorithmic image processing, calibration targets, and, increasingly, machine learning methods that perform denoising, detail enhancement, and artifact removal while aiming to preserve realism.

Beeldcorrectie raises considerations about authenticity and overprocessing, as extensive edits can alter factual content. It remains a core part of the imaging workflow, enabling clearer representation, better analysis, and more consistent color and tone across devices and media.
