Error using rgb2gray parse input

Hello,

I want to change an image into binary image, and I have the following code:

   for i = 1: OBJ.NumberOfFrames 
    NUM =  sprintf('%03d',i);
    IMG_ORIGINAL = read(OBJ,i);                                          
    IMG_GRAY     = rgb2gray(IMG_ORIGINAL);                               
    IMG_BINARY   = edge(IMG_GRAY,'canny',90/255);                        
    IMG_EDGE1     = IMG_ORIGINAL;                                        
    IMG_EDGE2     = IMG_ORIGINAL;                                        
    imwrite(IMG_ORIGINAL, strcat(SAVEFOLDER1,'\ORIGINAL_',NUM,'.bmp'));  
    imwrite(IMG_GRAY, strcat(SAVEFOLDER2,'\GRAY_',NUM,'.bmp'));          
    imwrite(IMG_BINARY, strcat(SAVEFOLDER3,'\BINARY_',NUM,'.bmp'));      

    [y1,x1] = find(IMG_BINARY == 1);     

    for j = 1:length(x1)                 
        IMG_EDGE1(y1(j),x1(j),1) = 255;  % R
        IMG_EDGE1(y1(j),x1(j),2) = 0;    % G
        IMG_EDGE1(y1(j),x1(j),3) = 0;    % B
    end

Then the following error appeared:

Error using rgb2gray>parse_inputs (line 80)

MAP must be a m x 3 array.

Error in rgb2gray (line 35) X = parse_inputs(X);

Can anybody help me with this, please? Thank you in advance

What does this say

[rows, columns, numberOfColorChannels] = size(IMG_ORIGINAL);

Then try this:

if numberOfColorChannels > 1
    % Only try to convert if it's a color image.
    IMG_GRAY     = rgb2gray(IMG_ORIGINAL);
else
  % Already gray
    IMG_GRAY     = IMG_ORIGINAL;
end

HI, Thank you for your answer.

I tried to put that command, but the following sentence appeared.

Undefined function or variable 'numberOfColorChannels'.

Any other idea to solve this problem?

Thank you.

You did not put the first line in , did you? Or if you did, check the spelling. Remove the semicolon from the end of the line and see what it spits out to the command window for the values of those variables.

Dear Image Analyst, Thank you very much for the suggestions. Sorry that I could not get back to this earlier.

You were right. When I put the first line, nothing happened. Then I tried to erase the semicolon, and this appeared: >> [rows, columns, numberOfColorChannels] = size(IMG_ORIGINAL)

rows =

   200

columns =

   576

numberOfColorChannels =

     1

then I erased the next semicolon signs, as below: >> if numberOfColorChannels > 1 % Only try to convert if it's a color image. IMG_GRAY = rgb2gray(IMG_ORIGINAL) else % Already gray IMG_GRAY = IMG_ORIGINAL end

IMG_GRAY =

Columns 1 through 28

I don`t know which semicolon signs I should erase, so I erased the whole semicolon signs.

Then hundreds of numbers came out.

Any suggestions about this?

Thank you.

Best regards, ulfah rimayanti

Put the semicolons back. You have a grayscale image, so don't call rgb2gray or you will get the error you say. Instead of this:

IMG_ORIGINAL = read(OBJ,i);                                          
IMG_GRAY     = rgb2gray(IMG_ORIGINAL);

say this:

IMG_GRAY = read(OBJ,i);

Dear Image Analyst,

Thank you very much for your answer. I put the semicolons back and change the command as you said, also edited other parts which mentioned image original and rgb2 gray.

Another error came: Error using imwrite (line 454) Unable to open file "C:\Users\Ulfah Rimayanti\Desktop\ulfah\Test_Normal_Right_29032012_141908\GRAY\GRAY_001.bmp" for writing. You may not have write permission.

So i think it may be better to put the whole command here: Original command: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% 2014/01/27 %%% %%% kiuchi.m %%% %%% Šá‹…•ÏˆÊ‰ð͈˗Š‚̃vƒƒOƒ‰ƒ€ %%% %%% %%% %%% 2.ƒƒCƒ“ƒtƒHƒ‹ƒ_‚ÌŽw’è %%% %%% 3.“Ç‚Ýž‚Ý“®‰æƒf[ƒ^Žw’è %%% %%% 1.‰Šú‰» %%% %%% 4.˜A”ԉ摜‚É•ÏŠ· %%% %%% 5.‰~‹ßŽ—‚Ì‚½‚ß‚ÌpixelÀ•Wƒf[ƒ^‚Ì“Ç‚Ýž‚Ý %%% %%% 6.‰~‹ßŽ—ƒAƒ‹ƒSƒŠƒYƒ€ %%% %%% 7.‹ßŽ—Œ‹‰Ê‚Ì•\Ž¦ %%% %%% 8.•ÏˆÊ—Ê‚ÌŽZo %%% %%% 9.ŽÀۂ̕ψʗʂւÌZ³ %%% %%% 10.‰ðÍŒ‹‰Ê‚Ìcsv•Û‘¶ %%% %%% 11.ƒGƒ‰[ƒJƒEƒ“ƒg‚Ì•\Ž¦ %%% %%% 12.•â‘«@ƒGƒbƒWŒŸo•û–@‚Ì‚¢‚ë‚¢‚ë %%% %%% by Shohei Uemura %%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Get the properties on the folder and look at the Securities tab. Does everyone have "Full control"? If not, give them full control.

[Ulfah]

Yes, everybody got full control. Any other ideas?

Thank you.

Can you copy any files into that folder using Windows Explorer, or does that also complain? Do you have the file open and locked in some other program, like Paint or Photoshop or something?

[Ulfah]

Yes, I could copy or delete files into the folder. About whether the file is being locked or not, I`m not really sure, but there is no lock icon on it, and I could play it using other programs (Video, windows media player, movie maker, even photo gallery), so I think it should be ok.

What do you think I should do then?

I`m sorry for asking so much.

Thank you.

To see if any file has a lock on it, you can use Unlocker: http://download.cnet.com/Unlocker/3000-2248_4-10493998.html

Then try using a very very simple script to simply write a line or two to a text file in that folder using fopen, fprintf() and fclose(), like

fid = fopen(fullFileName, 'wt');
fprintf('It worked');
fclose(fid);

[Ulfah]

Dear Image analyst,

Thank you for your suggestions.

I have downloaded the application you suggested and checked the file. No locking handle found. I typed that script to open the avi file which is going to be analyzed, and surprisingly an error came out: >> fid = fopen(C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada Nobuko_Left_19022014_144138.avi, 'wt'); fprintf('It worked'); fclose(fid); fid = fopen(C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada | Error: Unexpected MATLAB operator.

I don`t understand why that unexpected MATLAB operator appeared. I registered my own name for the MATLAB license and this is my own PC.

Is there any connection of this error with the previous error? "Error using imwrite (line 454) Unable to open file "C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada Nobuko_Left_19022014_144138\GRAY\GRAY_001.bmp" for writing. You may not have write permission.

Do you have any further suggestions?

Thank you very much.

Best regards,

You need to wrap the filename in single quotes. To be specific, you can't do this:

fopen(C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada Nobuko_Left_19022014_144138.avi, 'wt');

and you must do this:

fopen('C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada Nobuko_Left_19022014_144138.avi', 'wt');

Dear Image Analyst,

Thank you. The words below appeared when I typed what you said: >> fid = fopen('11803384_Shimada Nobuko_Left_19022014_144138.avi', 'wt'); fprintf('It worked'); fclose(fid); It worked>>

And when I typed only the first script, this appeared: >> fid = fopen('11803384_Shimada Nobuko_Left_19022014_144138.avi', 'wt')

fid =

     4

What should I do next?

Thank you.

Best,

You need to use fid in fprintf():

fprintf(fid, 'It worked');

Dear Image Analyst, Thank you for your reply.

I typed like you said:

fid = fopen('C:\Users\Ulfah Rimayanti\Desktop\ulfah\11803384_Shimada Nobuko_Left_19022014_144138.avi', 'wt'); fprintf(fid, 'It worked'); fclose(fid);

But nothing happened, nothing appeared.

Any ideas?

Thank you.

Sincerely,

Are you sure you're looking in the correct folder? A file called "11803384_Shimada Nobuko_Left_19022014_144138.avi" should have appeared (get created) and put into the folder C:\Users\Ulfah Rimayanti\Desktop\ulfah. If it didn't then it should have thrown an error message and you'd see red text. If you didn't see red text error message then look in the folder - the file should be there, and if it's there it means that you have permission to write to the folder and your problem lies somewhere else. That is, it's not a permission problem but some other kind of problem you need to figure out.

Dear Image Analyst,

Finally i was able to analyze the data. I just need to change IMG_GRAY = rgb2gray(IMG_ORIGINAL) into IMG_GRAY = IMG_ORIGINAL

Thank you for all the discussion.

Do you mind if I ask you 1 more thing? Could you tell me how to open workspace?

Thank you.

There is a function called workspace that will open and display the workspace panel if you're running the MATLAB IDE and not a compiled program.

workspace

If you want to see the Current folder panel with the files listed, issue the filebrowser command
