Table 3-1. Description of the image corrections/transformations which must be applied for each type of image correction and the workflow developed to carry it out. IMAGE CORRECTIONS / TRANSFORMATIONS WORKFLOW 1) Reflected Images (UV-VIS-IR) i. VIS images e Spatial inhomogeneities of light source e Spectral density of the light source and non-linear VIS camera response e Camera response (colour calibration for visiblereflected images) ii. IRR-UVR images: e Spatial inhomogeneities of radiation source e Spectral density of the radiation source and non-linear camera response IRR/UVR/false-colour e Image registration (for the creation of false colour images) e Generation of false colour images 2) Photo-induced Luminescence Images (UVL-VIVL-VIL) i. VIL images e Spatial inhomogeneities of light source VIL e Subtraction of ambient stray radiation ii. UVL images e Spatial inhomogeneities of radiation source e Subtraction of ambient stray radiation UVL e Correction for camera response/camera calibration e Pigment-binder interaction ili. VIVL images Not in scope (but could e As for UVL images? be developed based on UVL workspace) Version No. 1.0 116 Date : 14/10/2013
