Matlab导入B＆W 16位TIFF然后绘图？

Question

I have a 16-bit tiff that is b&w. It has no color mapping.

I import it like the following:

Tiff = imread('MyImage.tif')

That gives me a Variable with a value 'single' named Tiff. It is just a grid/matrix of intensity values for each pixel.

I have tried then using

image(Tiff);

But I end up with an image that is all Yellow.

If I do

imagesc(Tiff);

Then it kind of works, but its not grayscale, it is more like a heat map.

How do I plot the tiff on a graph? I want to be able to then then graph other lines on top of that tiff image.

Answer 1

Try this,

[I,cmap] = imread('your_image.tif');
img  = ind2rgb(I,cmap); 

To plot something on top of your image you can do this:

figure, imshow(img);
hold on;
plot(your_x_data,your_y_data); % or whatever yo want plot on top that image.
