Feature display

General Usage

Hi guys, I have implemented SIFT features in Julia. But my feature point display isn’t very prominent. My result looks like:

download488×650 145 KB

My display code:

function draw_points(image::AbstractArray, mask; c::Colorant=colorant"yellow")
    new_image = copy(uIn);
    new_image[mask] = c;
    return new_image;
end
draw_points(uIn, keypoints)

Can you guys help me make the display more prominent? Thanks!

Use a 2x2 or 3x3 block of pixels instead of a single one?
