[MATLAB] Import image to matlab

[moritz.buck]

A long thread on uploading to omero from matlab is there, but I have not seen the other story.

Basically, I just wanted to know if there is a simple function already implemented which basically takes an image ID and spits out a directly useable image matrix?

Thanks anyhow,

Hi Moritz,

there is no single function which does exactly what you want. However, such a function can be easily written using OMERO.matlab.

Below is a script example which connects to a server, load the image imageId and reads its first plane as a matrix.

Code: Select all

% Connect to the server
loadOmero
client = omero.client(server, port);
session = client.createSession(user, password);

% Get the image specified by imageId (integer or double)
ids = java.util.ArrayList();
ids.add(java.lang.Long(imageId));
proxy = session.getContainerService();
list = proxy.getImages('omero.model.Image', ids, omero.sys.ParametersI());
image = list.get(0);

% Get the pixels
pixelsList = image.copyPixels();
pixels = pixelsList.get(0);
pixelsId = pixels.getId().getValue();

% Initialize the rawPixelsStore and get the first plane
store = session.createRawPixelsStore();
store.setPixelsId(pixelsId, false);
plane = store.getPlane(0, 0, 0);
plane = toMatrix(plane, pixels);

Ok, it is so then,

thank you,
