Why is the python binding not complete ?

Is there any reason why some functions or classes are not available in the python binding of OpenCV ?

This page in the documentation indicates how to export elements for python, and it is quite easy to use.

For example, the high-level cv2.Stitcher class is not very tunable, because the ExposureCompensator cannot be selected, or the stitch function does not exist with ROIs parameters.

A pr is in progress and may be it will help you. "It is quite easy to use" yes but you should try yourself. Feel free to make a PR

the python bindings are auto-generated, and for some exotic c++ constructs there is no easy way to do this,

so none of those are exposed to the python api.

python binding it's easy ?

blender class is here

FeatherBlender is here

Now if you write:

   blender = cv.detail_FeatherBlender(1./blend_width)
   blender.prepare(corners, sizes)


blender.prepare(corners, sizes) TypeError: detail_FeatherBlender.prepare() takes at most 1 argument (2 given)

and if you write

        blender = cv.detail.Blender_createDefault(cv.detail.Blender_FEATHER)

Error :

  AttributeError: 'cv2.detail_Blender' object has no attribute 'setSharpness'
