problem in function imshow figure

I wante to use the following function

figure, imshow(I , []), title('Image');   I is image

but this command give error with some images not all images

I observed this error occure where the image have big size as 530 KB but if its size is 263 KB do not give error

please help me

**************************************************************

error is :-

??? Error using ==> imageDisplayValidateParams>validateCData at 114
Unsupported dimension

Error in ==> imageDisplayValidateParams at 31
common_args.CData = validateCData(common_args.CData,image_type);

Error in ==> imageDisplayParseInputs at 79
common_args = imageDisplayValidateParams(common_args);

Error in ==> imshow at 199
  [common_args,specific_args] = ...

Error in ==> code1_new at 6
figure, imshow(I , []), title('Image');

On one of the cases that fails, please check size(I) . If somehow you had a 4 dimensional array then that message would appear.

You could end up with a 4D array if you were doing something like Array(i,:,:,:) as in that case the singular first dimension would not automatically be removed.

Set a break point on that line. When it stops, in the command window, type this:

>> whos I

Tell us what it says.

I don't know what those 2 image planes mean. It's not an RGB image because those have 3 image planes, and it's not a gray scale image because those have only 1 plane. Your image has 2 - a very unusual number. Nonetheless, try this:

[rows columns numberOfColorChannels] = size(I);
image3D = cat(3, I, zeros(rows, columns));
imshow(uint8(image3D));

assuming your data is in the 0-255 range. Otherwise, use mat2gray:

imshow(uint8(255*mat2gray(image3D)));

it also show error...

No it doesn't. Here is proof:

% Create a 512x512x2 array
I = 255*ones(512,512,2);
[rows, columns, numberOfColorChannels] = size(I);
% Append on third plane (blue plane) of all zeros.
image3D = cat(3, I, zeros(rows, columns));
% Cast to uint8 and display.
imshow(uint8(image3D)); % Shows yellow image, as it should.

You did something incorrectly.

Hello, I have following code to plot 4 layers as, Clafimage= cat(3, A, B, C, D); figure, ClafImage=imshow(Clafimage,[],'InitialMagnification','fit');

But it is showing below error, Error using imageDisplayValidateParams>validateCData (line 117) Unsupported dimension.

Error in imageDisplayValidateParams (line 31) common_args.CData = validateCData(common_args.CData,image_type);

Error in imageDisplayParseInputs (line 79) common_args = imageDisplayValidateParams(common_args);

Error in imshow (line 220) [common_args,specific_args] = ...

Can anyone suggest how 4 or more layers can be show as a single classified image?

Thanks,

[Walter Roberson]
