What are Profilocolore's DeltaPick and DeltaViewer?

DeltaPick and DeltaViewer are software tools developed by Profilocolore for the comparative analysis of images of the same subject acquired at different times or before and after events or interventions on the work, allowing objective measurement of chromatic and spectral variations.

What is DeltaPick used for in the benchmarking workflow?

DeltaPick is software dedicated to data acquisition and preparation: it accepts groups of images with the same number and type of data, aligns the images of the two groups in pairs, can recalibrate the second group on the first, and allows resampling to change the resolution, making the images ready for analysis with DeltaViewer.

What information can DeltaViewer provide, and in what areas is it used?

DeltaViewer calculates changes in dE2000, colorimetric parameters (such as delta-L, delta-a, delta-b, delta-C, delta-h), and all available spectral bands. It is used for monitoring works over time, correlating with environmental and climatic monitoring, verifying the state of conservation before and after loans or moves, and evaluating and documenting restoration work.

Comparative image analysis

SPECTRAL IMAGING
PROFESSIONAL PHOTOGRAPHY

DeltaViewer, and the preparatory acquisition software, DeltaPick, are Profilocolore tools that allow you to obtain the objective difference between shots of the same subject taken at different times, or before and after events or interventions on the work itself.

DELTAPICK

Dedicated software for acquisition activities

DeltaPick is the preparatory software for using DeltaViewer. It accepts groups of images containing the same number and type of data, aligns the images in the first and second groups in pairs, and can recalibrate the second group based on the images in the first group if necessary. The software also includes resampling functions that allow you to change the original resolution.

DELTAVIEWER

Comparative image analysis

With DeltaViewer, you can obtain information on changes in dE2000, all colorimetric parameters (e.g., delta-L, delta-a, delta-b, delta-C, delta-h), and all available spectral bands.

The software can be used for various purposes:

Monitoring over time

Correlations between environmental/climate monitoring

Verification of the status of the work

before and after a loan or transfer

Assessments of restoration work

before and after comparison

Documentation of the operational phases of restoration
