overlay the image with transparency
显示 更早的评论
I have an image A which is
A = dicomread ('HYP-P-040.MR.ALL_PHYSICS_JAMESO.0004.0001.2019.12.11.14.31.46.328125.178069209.IMA'); %T2Axial image
and image B which is
B= dicomread('metab1_dyn=0001_slice=0001.IMA'); %metabolite 1
How can i overlay image B on A with transparency.
Both Image is attached for reference.
Please provide support.

Try this:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 18;
fprintf('Beginning to run %s.m ...\n', mfilename);
A = dicomread ('HYP-P-040.MR.ALL_PHYSICS_JAMESO.0004.0002.2019.12.11.14.31.46.328125.178068929.IMA'); %T2Axial image
subplot(2, 2, 1);
imshow(A, [], 'Colormap', gray(256))
B = dicomread('metab1_dyn=0001_slice=0001.IMA'); %metabolite 1
subplot(2, 2, 2);
imshow(B, [], 'Colormap', gray(256))
[rowsa, colsa, numberOfColorChannelsa] = size(A)
[rowsb, colsb, numberOfColorChannelsb] = size(B)
if rowsa ~= rowsb || colsa ~= colb
B = imresize(B, [rowsa, colsa], 'nearest');
end
subplot(2, 2, 3);
% Get RGB image
cmap = jet(256);
rgbImage = ind2rgb(uint8(255 * mat2gray(B)), cmap);
imshow(rgbImage, []);
% Put both images into subplot
subplot(2, 2, 4);
ha = imshow(A, [], 'Colormap', gray(256))
hold on;
hb = imshow(rgbImage)
% Set opacity/transparency to something less than 1 (alpha).
% 1 is the default and it means the last image is opaque and the image below can't be seen.
hb.AlphaData = 0.4;

I'm not able to use your code to open your images. Are you sure you attached the right files and right code to read them in?

They aren't even the same size, so how do you want to overlay them? Resize B to match A?
A = dicomread ('HYP-P-040.MR.ALL_PHYSICS_JAMESO.0004.0002.2019.12.11.14.31.46.328125.178068929.IMA'); %T2Axial image
subplot(2, 2, 1);
imshow(A, [])
B = dicomread('metab1_dyn=0001_slice=0001.IMA'); %metabolite 1
subplot(2, 2, 2);
imshow(B, [])
