MATLAB: Error in code for windowing

image DICOM

Hi i wrote a code in which i applied a linear equation ax+b=0 to a image that is in format DCM. I think my code is fine, just at the end of the code i have "Array indices must be positive integers or logical values.

Error in windowin (line 38) transimage(i,j)=line(rho);"

can someone tell me why?

i attach the code..

rho = img(i,j) can be 0 or even negative. Your variable line is an array. So line(rho) is asking to index line at that location. But you cannot index at negative or 0.

Note: your DCM file appears to be a DICOM file. You should use dicomred() instead of the code you are using.

 Could not open "rice.dcm" for writing

This can mean, that the file is write-protected or you do not have the permissions to write in this folder. Check this either in the file explorer of the operating system or by the fileattrib command.

This tries to create the file in the current folder:

dicomwrite(I,'rice.dcm',info)

Better define the folder to write to explicitly. fullfile might be useful here.

MATLAB: Do I receive missing attribute errors when using the DICOMANON function in Image Processing Toolbox 5.0.2 (R14SP2)

This behavior occurs when the source DICOM image is missing the "SOPClassUID" attribute. The following code example demonstrates how to work around this issue:

imageInfo=dicominfo('image.dcm');
values.MediaStorageSOPClassUID=imageInfo.SOPClassUID;
dicomanon('image.dcm','anonimage.dcm','update',values);
