%%meanshift parameter
I was trying to make Region Adjacency Graph from MEAN SHIFT SEGMENTED Image
Got some Errors .Here is my code and my some result,help to fix the error
bw= 0.2; % Mean Shift Bandwidth
%%input
I = imread(fullImageFileName); % Original
%%ncut parameters
%SI = 5; % Color similarity
%SX = 6; % Spatial similarity
%r = 1.5; % Spatial threshold (less than r pixels apart)
%sNcut = 0.14; % The smallest Ncut value (threshold) to keep partitioning
%sArea = 220; % The smallest size of area (threshold) to be accepted as a segment
tic
[Ims Nms2]=Ms2(I,bw);
toc
subplot(331),imshow(I),title('Original Image');
subplot(332),imshow(Ims),title('Means Shifted Image');
tic
rg=rgb2gray(Ims);
subplot(333),imshow(rg);
level = graythresh(Ims); %# Compute an appropriate threshold
BW = im2bw(rg,level); %# Convert grayscale to binary
subplot(334),imshow(bw);
[labeledImage numberOfRegions] = bwlabel(BW);
subplot(335),imshow(labeledImage);
dist = bwdist(labeledImage);
subplot(336),imshow(dist);
% compute overlay image for display
ms=uint8(Ims);
tmp = uint8(double(I).*(ms>0));
ovr = uint8(cat(3, max(I, uint8(255*(ms==0))), tmp));
ovr=double(ovr);
subplot(441),imshow(ovr);
%[n,e]=imRAG(labeledImage);

Concatenation is not the way to Overlay two images. imshow one image, hold on, and plot the segmented overlay on the same axes using plot function.

Then you changed your expected result. My answer would have given you the original expected result of having two color images appear blended, on top of one another. This answer says to get some kind of coordinates, for example using bwboundaries() or something, and then plotting them as lines in the graphical overlay. Still another way is to use methods discussed in Steve's blog: http://blogs.mathworks.com/steve/2009/02/18/image-overlay-using-transparency/

Why did you cast ovr from uint8, which will display fine, to double, which won't? Don't do that.

You can't show a 6 color channel image. You'd have to average them:
averagedImage = uint8((double(rgbImage1) + double(rgbImages2))/2);
imshow(averagedImage);
