QUESTION
I have an image that has different shades of black at the edges and a bit of red in the centre. I want to convert all the black pixels to transparent using opencv. I'm new to opencv so I'd appreciate your help.
I tried following what fireant said in the link: overlay a smaller image on a larger image python OpenCv, but it didn't work. Here's the code I have so far:

Answered 2019-Aug-21 at 15:29You need to use alpha blending to combine the lens flare with the background image. Check out this tutorial to find out more about alpha blending. Here is the stript that I used:
QUESTION
I'm trying to overlay random images (natural scene images should be overlayed with sign images) using OpenCV and Python. They can vary in size, file extension and no. of channels (and many more, I guess). So I'm resizing the sign images according to the size of the natural scene image and put them onto the latter.
I have implemented fireant's code found here: overlay a smaller image on a larger image python OpenCv
But it only works for images with 4 channels.
Using cv2.addWeighted() always crops the larger image (scene image) to the size of the smaller image (sign image). Has anybody an idea how to do that? Help is highly appreciated.
EDIT: See the expected output below. At first the, escape route sign and the background are separate images.
And this is my code, it is working, but since a lot of my images seem to have only 3 channels, I would like to get it working for those also.
...ANSWER
Answered 2018-Nov-26 at 18:42thanks to @DanMašek hint and How to crop or remove white background from an image, I have worked out a solution. The following code will first remove white background from the smaller image, then set all images to 4 channels and then overlay the larger image with a smaller image. Works for me.

objects now have format == 17
, which is:
ANSWER
Answered 2017-Feb-04 at 21:35The image format should be YUV NV21 not NV12. OpenCV can convert an image from that format to BGR or RGB.
Just a guess, it seems you're using RGB instead of BGR, the image after NV21 with BGR looks like this:
