Plotting Image intensity from Matrix
显示 更早的评论
Greetings to all ! I have a 3D matrix which represnts a Sheep_Logan Phantom. Is there any way to plot the intensity ogf the image matrix both in horizontal and vertical direction? I can do the same things with saving an image but I want it from the matrix that I have attached.

Do you want the profile along some certain row or columns, like
rowProfile = squeeze(image3d(rowNumber, :, sliceNumber));
columnProfile = squeeze(image3d(:, colNumber, sliceNumber));
or do you want the average profile across the entire plane? Or the max projection? Have you seen slice?

@Image Analyst, Thank you for your reply. Yes I want the Intensity profile along some certain row or columns ( for a specific slice) for a specific direction (Horizontal/Vertical).
It should be 2D plot ( Having the shape of Gaussing Bell). Kind of Following.

OK, but did my code not work? Did you even try it? It should produce a 1-D plot of the gray scale, like you showed. If you want a 2-D profile, then that is an image and you'd replace one of the number variables by a colon.

I would first get the entire plane as a 2-D image and then use max for the direction you want. For example
image2d = randi(255, 5, 4)
verticalMaxProjection = max(image2d, [], 2)
horizontalMaxProjection = max(image2d, [], 1)
