Overlay a plot on an image
171 views (last 30 days)
I have to overlay a plot on a image. Here is my code:
Imm = imread('imageLeft.png');
where Imm is the image (634x484x3 uint 8) while pos_sensor_Lx and pos_sensor_Ly are two column vectors 3487x1 double with values all normalized between [0;1].
When I plot the vectors and the image separately, I get this results:
Overlaying them, I ideally had to see the scan path well distribuited on the white and red dots of the image. Anyway when I overlay them I can't see the scan path over the image because of the very small values of the vector elements. Here the result I get:
All the values are clustered as shown.
Is there a way to adjust the image dimensions or the value of the vector elements to get the result I want?

Use the following code as an example to normalize your 2nd data based on the first and overlay it on the image.
Imm = imread('image.jpeg');
% Synthesis - [0,1] Normalized random data
P = rand(1,50); % -> X-variable
Q = rand(1,50); % -> Y-Variable
% Normalizing with respect to image pixels and quantizing
C = size(Imm)
P = uint16(P*C(1));
Q = uint16(Q*C(2));
% Overlay Plot
