Hi all,
I have the image 20 images in subplot figure. then the image have three sphere.
Anyone can help me to calculate all the three sphere.
I used this command
T = regionprops('table', outt22,'Area','Centroid')
note: outt22 is the mask of my three volume. but it show only one area of the circle among the images.
T =
1×2 table
Area Centroid

Yes I have individual images.
But if i view individual image, it will be have 20 figure.
So I have to calculate the volume every single image. With repeatition command.
What I supposed is just view 20 images in one subplot, then calculate for all three sphere volume

You have to calculate that for each image and store into array. Calculating in the attched image is not feasible.

You need to stack these images together into a 3-D volumetric image, and then use regionprops3() instead of regionprops().

I wrote this, then function
image3d = zeros(256, 256, numFiles, 'uint8');

I thought that you knew in advance how many rows and columns your images have. If not, you can easily find out by just reading in one of them.
yourImage = imread(yourFileNameOfOneImage);
[rows, columns, numberOfColorChannels] = size(yourImage)
