Fig. 5 The geometric factor ((G_{mathrm{ESA}})) for wide (red) and narrow (green) channels.
The blue and green channels were combined in the merged images.
In addition, the spatial similarity between the green channels is estimated for the restrict decision of the edge direction.
The real-time video stream was processed using a real-time spectral unmixing of the red and green channels.
An analysis of the red and green channels demonstrates dissimilar kinetics, suggesting the co-existence of two or more temporally shifted luminescence pathways.
The values of each LR image are obtained as followed by using the definition of the difference between the red and green channels [7]: (21).
where represent the Bayer CFA samples at pixel index and the LR image channel is green, red, blue, and green channels according to the sampling index, respectively.
It should be noted that the UVL image still has contributions from the blue and green channels (as expected) but in the VIVL images this has almost disappeared.
The fully interpolated green channels which have much information on edges are utilized to improve interpolation accuracy of the red and blue channels.
The vertical profiles of the F-region emission obtained from the red and green channels of the A-IMAP observation have a good agreement with these studies.
The intensity of white pixels (only red and green channels) in the maps are interpreted as 2D vectors, which are then used to define how far input pixels must be pushed.
