Automatic Analysis of Thermocolor Paints for Heat Flow Measurements in Wind Tunnel Facilities
An automatic analysis of thermocolor paints is done. All the images have been masked, corrected from non uniform illumination and registered. Then, after having compared different colorimetric representation systems (R-G-B, I-H-S and K-L bases), we use the bidimensional histogram to extract the different colors and so detect the iso-flux lines on each image. A relative thermic exchange map is obtained by superimposing a sampling of processed images.
