Well thats great i just wanted to tell you how algorithms work .. while implementing practically the region is very big with many pixels at that time as you said we try to select the center pixels so that the steps used are less .. Thanks for sharing your views 👍
@@business-hy3lb sure you can refer Gonzales, if you want i can send you the ebook I have the 2nd edition 2002 In that book page 535 has the region filling algorithm It says " beginning with a point p inside the boundary " this justifies any point inside the region can be point p
these all examples in this video and other examples in other videos on this channel are taken from "Digital_Image_Processing by Gonzalez and Woods". So try reading the book rather than watching brief intro. of each topic.
