Hello

Matlab tries to call a function with the name "SegmentBone" as you can see from the example but I get the error of duplicate name and that Matlab cannot define it. There is only one SegmentBone.m in the folder. Why duplicate name?

Error: File: SegmentBone.m Line: 7 Column: 18
Function with duplicate name "SegmentBone" cannot be defined.
Error in Test1 (line 38)
imSeg = SegmentBone(im, 10e6, 0.031);

I use that code. There is no SegmentBone.m in the same script anywhere else or in the working folder.

% Apply the bone segmentation to test image and show the results
clc
close all
clear all
 
path = imread('2A.bmp');
imROIminX = 159;
imROImaxX = 536;
imROIminY = 33;
imROImaxY = 410;
% path = 'Z:\Data\Cadaver_Experiment_2\Data\MaleCadaver\1\center\im';
% imROIminX = 159;
% imROImaxX = 536;
% imROIminY = 33;
% imROImaxY = 410;
 
i = 69; %81;
lp = sprintf('%s%04d.bmp', path, i);
im = imread('2A.bmp');

1) Yes it's the correct function

This is the SegmentBone.m function. It starts at line 7 where all the previous lines are comments in green

function imSeg = SegmentBone(USimage, USfreq, USdepth)
 
[imH, imW] = size(USimage);
 
% calculate the segmentation parameters from US image parameters
boneTh = 1/8;   % used for masking
 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Downsampling
DownSampleFactor = 4;
% filter
Gsigma = 6;
hsize = floor(Gsigma*3)*2+1;
h = fspecial('gaussian', hsize, Gsigma);
imBlured = imfilter(USimage, h, 'replicate', 'same');
imBlured = imBlured(1:DownSampleFactor:imH,1:DownSampleFactor:imW);
imBlured = AdjustContrast(imBlured);
figure, imshow(imBlured)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
h = [0 -1 0; -1 4 -1; 0 -1 0];
imBLOG = imfilter(imBlured, h, 'replicate', 'same');
imBLOG = (imBLOG>0).*imBLOG;
imBLOG = imBLOG/max(imBLOG(:));
figure, imshow(imBLOG)
 
% To make the algorithm faster, keep track of the points that are probable
% to be the bone surface
% First: Apply the threshold to the image (this is a loose threshold)
imMask = (imBlured >= boneTh);
[imH, imW] = size(imMask);
BorderRigeon = round((0.002/USdepth)*imH);
imMask(1:BorderRigeon,:) = 0;
 
% calculate the weight for underneath shadowness
Wshw = CalcBoneShadow(imMask, imBlured);
figure, imshow(Wshw);
 
% calculate the intensity weight
Wint = imMask .* (imBlured+imBLOG);
Wint = AdjustContrast(Wint);
figure, imshow(Wint);
 
 
% calculate the total Boniness, (Multipication prefered over addition) 
Bness = Wshw.*Wint;
Bness = Bness/max(Bness(:)); % normalize
figure, imshow(Bness);
% imwrite(Bness, 'results\cadaver_2_50_Bness.bmp', 'bmp');
% Find bone surface using Dynamic Programming
% Smoothness will be applied through DP
% Presence of bone will be also determined using DP
% imSeg = FindBoneDP(Bness);
F0 = 50.0;  F1 = 100.0;  Bth = 0.55;  % bone threshold between 0 and 1
JumpConst = 1.5;
% imSeg = FindBoneDP(Bness,F0,F1,Bth,JumpConst);
imSeg = SegmentBoneDP(Bness,F0,F1,Bth,JumpConst);
 
end

I use the line

mex SegmentBone.cpp

This should do the compiling from cpp to Mex. However, I get the error

mex SegmentBoneDP.cpp

Anyone who can responsibly help me?
