plotting data into an image with plot function

Question

0 个投票

Hello everyone I got the following problem.

I loaded an image into MatLab now the image has a matrix of 720x752x3

I have a Data matrix that is 10x2

I want to plot the datapoints into my image but when I use normal plot I get an error that my data has more than 2 dimensions. Does anyone have an idea how to fix that?

Thanks for helping me

Ahhh, now things are tidy again ;)

@ Andre589 I'd be glad to help but I agree with Jan that we need to see your code.

clear all
close all
I = imread('test.png');
imshow(I)
C = [115 182
     225 113
     328 58
     515 426
     422 460
     309 535
     100 150
     478 628
     322 411
     490 541 ];
 
     plot(C,?)

The result should look like I get the data points I have in my Matrix C into my image I

I'm guessing that you want to plot the coordinates listed in C on top of the image.

I = imread('test.png');
imshow(I)
axis on %this will show you the axis ticks; note the y axis is reversed!
hold on
plot(C(:,1), C(:,2), 'bx')
