feature image equal_v0.1
The feature-image-equal takes two images as input. According to parameters, its role is to fit both image exposition. It can align both image on the lowest exposure or the contrary. As output, both images are exported.
Grayscale images are expected by the software. If color images are given as input, the OpenCV image reader convert it automatically into grayscale images.
The feature-image-equal software expects the following arguments and parameters. Starting with the stream parameters :
--input-a -a, --input-b -b
Path of the two input images.
--output-a -c, --output-b -d
Path of the two output images. Output image a correspond to input
image a.
Exposure alignement mode arguments and parameter :
--mode -m
Mode of exposure alignment. If the mode is set to one, both output
images will fit the highest exposure. Any other value will align
both image to the lowest exposure.
Considering the two following grayscale images taken using an Eyesis4Pi camera in Geneva that shows different exposures :
the exported images using highest exposure alignment mode are given by the following images :
and becomes as follow when using lowest exposure alignment mode :
One easily observe that highest exposure alignement mode can be extremely dangerous in case of high exposure differencies between the two input images.
The software binary can be build using its specific makefile by simply typing in its base directory :
$ make clean && make
The binary is placed in the local bin directory and is not copied in the feature-suite main bin directory. To generate the documentation, use the command :
$ make documentation
When documentation is generated, the previous one is preliminary removed.
