SpectraPick
Colorimetric and spectral calibration
Category
SPECTRAL IMAGING
SpectraPick is software based on artificial intelligence and computer vision, and automatically produces:
Immagini CIELAB con errore dE2000 < 2
False color infrared images and associated grayscale IR images
False-color ultraviolet images and associated grayscale UV images
. This is another false-color infrared image that provides a lot of detail.
In addition to these standard data, SpectraPick allows you to define virtual filters. Each virtual filter will correspond to a B/W image that simulates the scene seen through that filter.
At the end of calibration, all images—colorimetric, spectral, false color, imported, and from virtual filters—are organized into folders, and all images produced are perfectly aligned with each other.
The number of bands that can be obtained while maintaining the same radiometric accuracy is approximately 6 times the number of shots (taken with the appropriate filters). With two shots (PFCL-A and PFCL-B filters), 13 bands are obtained, one every 50 nanometers, while with three shots (PFCL-A, PFCL-B, and PFCL-MBP filters), 18 bands are achieved.
How it works
Acquiring the starting images is simple and does not require any special photographic knowledge because it is guided by a robust, error-proof procedure that covers all shooting conditions, even those that would normally pose difficulties for an experienced photographer.
The software accepts images captured in both standard formats (TIFF, JPEG, PNG) and in the RAW format used by most commercial cameras. The RAW format provides the best quality and precision.
If you have images from other types of sensors (X-Ray, XRF scanning, THz, etc.), these can be added to the photographic images. In this case, at the end of the calibration process, you will obtain not only colorimetric and spectral images but also these images from other sources, resampled and aligned to obtain final image sets that are perfectly superimposable and directly usable for subsequent comparative analyses.
Some examples of how the SpectraPick process works
This figure shows how a two-filter acquisition, through AI calibration, leads to a 13-band spectral image (bandwidth 50 nanometers; line and text in green), and a 5-filter acquisition leads to a 34-band spectral image (bandwidth 20 nanometers; line and text in blue).
