I have loaded test image nose and moustache images but now finally how can i join or overlap all the things and also in other discussion forums they were mentioning about alpha number whats that exactly?
Doubt about overlapping images
Hey @Sid10,
I won’t be able to help you with your first doubt otherwise it won’t be a challenge anymore (Hint: You can find the solution in the discussion forum itself).
Regarding the alpha channel/number, png images have 4 channels instead of the typical 3 (BGR). The 4th channel is the transparency channel and decides how transparent a particular pixel is. You can find out more about it here
Hope this helps!
