• Enhancements to ICC Color Capabilities

• Enhancements to the imdistline Function

• setColor Method Accepts Predefined Color Strings

Enhancements to DICOM Capabilities

This release includes the following new features and enhancements to the DICOM capabilities of the Image Processing Toolbox:

• The toolbox includes a new function, dicomlookup, that provides a way to find the name of an attribute in a DICOM data dictionary by specifying its group and element tags, or find the group and element tags for an attribute by specifying its name.

• The performance of the dicominfo function has been significantly improved

New Symmetric Option with graycomatrix Function

The graycomatrix function now supports a new option: 'symmetric'. With this option, you can create a gray-level co-occurrence matrix (GLCM) that is symmetric about its diagonal. This is consistent with the GLCM definition given by Haralick in his 1973 article. For more information, see graycomatrix.

Enhancements to ICC Color Capabilities

The toolbox includes the following enchancements to the ICC color capabilities:

• The applycform function can now transform colors using profiles that contain parametric curve types.

• The iccread function now supports named colors in ICC profiles.

Compatibility Considerations

The whitepoint function, when used with the 'd50' argument, returns different results in R2006b than it did in R2006a. The previously returned XYZ color values were incorrect according to the current interpretation of standards. If your algorithm depended on the old values, you might see subtly different results.

Enhancements to the imdistline Function

This release includes the following enhancements to the imdistline function:

• The imdistline function now uses a different cursor shape at its endpoints to highlight that these endpoints can be grabbed to change the length or direction of the line. The function uses a hand cursor over endpoints and a fleur cursor over the body of the line.

• The imdistline function reference page now includes an example that shows how to use the XData and YData properties of the associated image to express distance in non-pixel units.

Compatibility Considerations

The Distance Tool's getAngleFromHorizontal method now returns a value between 0 and 180 degrees. Previously, this function incorrectly returned a value between 0 and 90. For an explanation of how getAngleFromHorizontal calculates this angle, see the imdistline function.

setColor Method Accepts Predefined Color Strings

The setColor method of the imdistline, imline, impoint, and imrect functions accepts an RGB triplet or the short- or long-name version of the MATLAB predefined color names.
