MATLAB: Disable border blue in scatter plot

plot

I'm building a scatter plot and I would that some points in the plot should be red.

scatter(nodes(:,2),nodes(:,3),'filled');
hold on;
scatter(heads(:,2),heads(:,3),'^','markerfacecolor','red');

unfortunately if they are red they have still the border blu.How can I delete the blue border?

you also need to set the markeredgecolour property

MATLAB: Segmenting or Thresholding Blue

Most color images are stored in RGB format. In other words, they are 3D matrices where the first, second, and third matrix represents the intensity of red, green, and blue respectively.

In your case, the simplest solution may be to isolate the blue-channel and perform segmenting on that image:

imageRaw = imread("source");
imageBlue = imageRaw(:,:,3);
imageBlueThresh = graythresh(imageBlue);
imageBlueBw = im2bw(imageBlue,imageBlueThresh);

What would you like to do with the segmented regions though? Remove everything else from the image? Outline them? Quantify something within those regions?
