why i m getting this error "Array indices must be positive integers or logical values. or min=min(dist);" please help me out?

%% Test Image

[fname,path]=uigetfile('.jpg','Provide a Image for Testing');

c=strcat(path,fname);

im=imread(fname);

imshow(im);

title('Test Image');

%% Fond out which Class it Belongs to

Ftest=FeatureStatistical(im);

%% Compare with Database

load db.mat

Ftrain=db(:,1:2);

ctrain=db(:,3);

for(i=1:size(Ftrain,1))

dist(1,:)=sum(abs(Ftrain(1,:)-Ftest));

end

min=min(dist);

if (min<3)

m=find(dist==min,1);

det_class=cstrain(m);

msgbox(strcat('dectected class',num2str(det_class)));

else

msgbox('This person is not register');

end

Answer 1

You cannot call the min function while a variable named min exists in the workspace. Rename or remove the variable.

i am try to run this code but when i was try to recognized then its show always same result "detected class 1"

Answer 2

[madhan ravi]

clear all % at the very beginning, this clears the variable named ‘min’

MIN = min(dist); % change your line to this, means u have to change all the min variable to MIN , naming a variable min is a bad idea which shadows the inbuilt function min(...)

>> image_classification

Array indices must be positive integers or logical values.

Error in image_classification (line 16)

MIN=min(dist);

again error brother
