Hi. Here I have an image with yellow boundary as salient region (attached image). How can I extract the ordered list of x and y coordinates within the yellow region from the image?
Thank you in advance.

How about the following?
I = imread('untitled.jpg');
Ilab = rgb2lab(I);
BW = Ilab(:,:,3) > 25;
se = strel('disk',20);
BW = imclose(BW,se);
BW = bwareafilt(BW,1);
xyCoordinates = regionprops(BW,'PixelList');
