Hi,

I'm having the same problem here when I tried to get my data. I've got 41 cell and each cell contains 480x640x3 uint8.

I can display data in moving image but I also cannot display the variable of the data due to the more than 524288 elements issue.

I've tried to extract into individual RGB channel but it is not working. How to get the data of 480x640x3 uint8 in each cell?

Help me, please...

Thank you

Regards

Hana

Please start your own question. You can display it with imshow() but not in the variable inspector. Only 2-D images can be displayed in the variable inspector (workspace). Not sure what you mean by moving image. Do you mean a video? Again, start your own question if you need more help.

Hi,

Sorry for the mistake I've done. I've read somewhere in the forum - it is better not to post a new question for the same topic. I may misinterpret it and be asking here since I thought to have the same problem as Ms. Sara.

I will post my question on the new thread. Thank you for telling me this. https://www.mathworks.com/matlabcentral/answers/402695-how-to-access-data-with-more-than-524288-elements

P/S It is yes to your question.

Thank you once again

Regards

I can't find your new question. If extracting the color channels to individual channels like in my answer below really doesn't work for you then edit your comment above to give a link to your new question.

It looks like a color image. So break it up into separate color channels and look at just one color channel at a time:

% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);

This is my coding and I just put your suggestion coding.

BW = imread('agar2.jpg');
% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);

but i get error: Undefined function rgbImage.

I know you've probably figured this out, but just in case... You need to access your own RGB image, in this case, use

redChannel = BW(:, :, 1);

etc.

BW is a name the Mathworks often gives for binary images. It means Black and White, meaning no gray scale, no RGB. So you should change your code like this:

rgbImage = imread('agar2.jpg'); % Read in RGB image.
