I am writing a program wherein i need to use connectedCompponents(img, label, connectivity= 8, type= CV_32S ). All I know is that this function returns an integer stating the no of components in the image. Then what does Mat label suggest? Thanks in advance
The input is a binary image. Any contiguous area (with connectivity 4 or 8, as per the argument) is given a label.
label is the same size as the input image, and of type CV_32S, as you passed the argument. Each pixel in label contains the number of the blob it belongs to, with 0 being no blob. You have a maximum label value of the return value - 1.
So can I print the mat label? According to the explanation the background should be black and other objects having color corresponding to their label value.
What do you want to actually do with it? Of course you can print it, but since I don't know what you're doing, I can't tell you if it does anything useful.
The background does have a value of 0, and anything above 0 is a blob.
Thank you so much!
