ThermovisorImages.jl is designed to process static thermal images stored as matrices in CSV files or as image files. It treats each matrix element as a temperature value. ThermovisorImages.jl provides functions to calculate temperature distributions and perform statistical analyses of temperatures within Regions of Interest (ROIs), such as circles, squares, rectangles, or along lines. ROI objects can be fitted to image patterns (regions that stand out from the background). It is also possible to evaluate statistics across multiple ROIs, including distributions of side length, area, and perimeter.
ThermovisorImages.jl also provides functions to recalculate the temperature distribution of the entire image (or its part within the ROI or labeled pattern), taking into account the emissivity of the surface and the spectral range of the infrared camera.
This package was designed to study the temperature distribution across the heated sample for the emissivity measuring facility described in this paper
The following figure shows the image with the ROI object on it:
The following figures show temperature distribution along the inclined line, and radial and angular distribution of all points within the ROI
Main functionality of the package is demonstrated in the Pluto notebook. Static version of this notebook is available at ThermovisorImages-test
