compute_histogram support is available. hist2table support is available hist2image still to be performed. Function for 3c to 1c to be added quickly! Reported-by: Julien Lengrand-Lambert <julien@lengrand.fr> Signed-off-by: Julien Lengrand-Lambert <julien@lengrand.fr>

Here is a simple example of an histogram calculation on a grayscale image in
|
|
Python.
|
|
|
|
The histogram calculation is performed using the OpenCV library. In order to
|
|
simplify the process, an Histogram class has been created, which contains all
|
|
necessary data for a proper output image creation.
|
|
|
|
The final output is an IplImage in this script.
|
|
To end the script, the user simply needs to hit a keyboard key with the input
|
|
image in the foreground.
|
|
|
|
For now, only the grayscale function is available, but color images support
|
|
should be added soon.
