W shape over here, it would replace the one we already had, so we no longer have the other sky divers will choose undo if I want to add to the other sky diver I need to hold on the shift key could shift means add to what we already have and all the strong my lasso around that then again I'll go back to my magic wand tool and I will say let's take away from this election and that's by holding on the option key alton windows and I will click right where the sky is within that selection to say get rid of the blue sky from thesis election as a whole and more spot there and I could get that selected so that makes sense some times that's if I had twelve birds in the sky and I only needed one of them why not just do a simple magic wand around one and then used or not a magic wand a lasso around one and then use the magic wand to say hey shrink that lasso down to eliminate this blue sky area that's there so there's all sorts of ideas we can explore like that but it's really nice field use it and we can use the same ideas holding on shift to add or option to take away on the simplest tools or the most complex there so universal that you just really need to drill him into your head most people I find think about him on a very simple level but I use him even on the most complex tools that photo shop offers we have a question when you make that selection around, whatever the object is, do you have to be in the blue area? If it's overlapping, will it mess up the selection? If I were to make this election over here and overlaps, some of the smoke let's say like that, then when I tell it to take away by holding on the option key, and I click here, it would most likely relieve some of that smoke up at the top.

The key that takes away is option on a mac all tum windows I haven't held down right now, and I'm just going to click inside the selection that's here, right where the sky is to say take away the sky so the magic wand to will click I could get that I'll do it again to the other sky diver in this case, I'll grab my lasso tool usually fired just dra. I want to get the sky divers, so what I'm going to do is use the lasso tool to first tele photo shop what part of the image to think about? And then I'll switch to a different simple tool, like the magic wand tool, and I'm going to hold down the key that takes away from things. But there are some other ideas we can use here.
Well, I could select the sky choose inverse so that we have all the birds in the sky, and then I could use the keyboard shortcuts of either shift to add to a selection or options option to take away and take away the other birds. Num, img, mask, rect = cv2.Another ideas let's say there was ten birds in the sky, and I only wanted to get one of them. # Find button based on background color via flood-fill I'm happy to see other suggestions on more efficient ways to tackle this. I think I've gotten this pretty close (major credit to this solution: ). # Define the button background color at exit coordinatesīackground_color = img, top_left]
Img = cv2.imread('C:/Users/xyz/PycharmProjects/findTextImage_v0/testBank/sampleScreen.png')

Any tips on how to accomplish a "magic wand" selection of pixels based on color? import cv2 I then need to store the top left and bottom right coordinates of that box.
I'm going through images and finding "buttons" based on their text.
