to show 5 images having smallest eucledian distance with respect to query image.

Suppose i have one query image and a database in matlab having 10 images..i have read out and showed one image which has smallest eucledian distance with respect to query image.but now i want to read and to show atleast 5 images from that database which has nearest eucledian distance with respect to query image,that means i want to read and show 5 images in 5 different windows all together.

my program for reading and showing one image with respect to query image which has smallest eucledian distance is as follows:

G=imread('spine.tif');

H = adapthisteq(G,'clipLimit',0.01,'Distribution','rayleigh');

[rows cols]=size(H); 

[c1,s1]=wavedec2(H,1,'db1');

X=c1;

figure,imshow(G);

figure,imshow(H);

fileFolder=fullfile(matlabroot,'toolbox','images','imdata');

dirOutput=dir(fullfile(fileFolder,'*.tif'));

fileNames={dirOutput.name}

n=numel(fileNames)

g=zeros(1,n)

for k = 1 : n

fileNames1=strcat('fullfile(fileFolder)',fileNames(k)) 

I = imread(fileNames{k});

J = adapthisteq(I,'clipLimit',0.01,'Distribution','rayleigh');

J = imresize(J, [rows cols]);

[c2,s2]=wavedec2(J,1,'db1');

Y=c2;

E_distance = sqrt(sum((X-Y).^2));

g(1,k)=E_distance;

if g(1,k)==0

      w=k;

      end

end

disp(g);

II=imread(fileNames{w});

figure, imshow(II);

How will i read and show atleast 5 images from that database which has nearest eucledian distance with respect to query image,that means i want to read and show 5 images in 5 different windows all together.

i want to compute euclidean distance of a given image with the every 5 images one by one i want to see which image out of 5 which has the least euclidean distance and to show them one by one...please help me..thank you

Run your above code, except removing the disp(g) on downward, and adding in the missing "end" for the "for n" loop.

Afterwards, find the 5 smallest values in g. The indices of those 5 values tell you which fileNames(k) to read and display.

SORRY I AM NOT GETTING YOU..PLEASE WRITE THE CODE FOR ME.THANKS

[Walter Roberson]

G=imread('spine.tif');

H = adapthisteq(G,'clipLimit',0.01,'Distribution','rayleigh');

[rows cols]=size(H);

[c1,s1]=wavedec2(H,1,'db1');

X=c1;

figure,imshow(G);

figure,imshow(H);

fileFolder=fullfile(matlabroot,'toolbox','images','imdata');

dirOutput=dir(fullfile(fileFolder,'*.tif'));

fileNames={dirOutput.name}

n=numel(fileNames)

g=zeros(1,n)

for k = 1 : n

    fileNames1=strcat('fullfile(fileFolder)',fileNames(k))

    I = imread(fileNames{k});

    J = adapthisteq(I,'clipLimit',0.01,'Distribution','rayleigh');

    J = imresize(J, [rows cols]);

    [c2,s2]=wavedec2(J,1,'db1');

    Y=c2;

    E_distance = sqrt(sum((X-Y).^2));

    g(1,k)=E_distance;

    if g(1,k)==0

        w=k;

    end

end

Then, find the 5 smallest values in g. If the indices of those 5 smallest values in g are k1, k2, k3, k3, k5, then

for k = [k1 k2 k3 k4 k5]
  figure;
  imshow( imread(fileNames{k}) );
  title( sprintf('distance %g to file %s', g(k), fileNames{k}) );
end

[diva dave anthony]

ki k2 k3 k4 k5-error coming,it tells indefinite variable.if i give for k =1:5 will it be wrong?

[Walter Roberson]

I wrote " If the indices of those 5 smallest values in g are k1, k2, k3, k3, k5,". So when you find the 5 smallest values in g, assign the indices to k1, k2, k3, k4, k5 and proceed.

Using k = 1:5 will not be right: that would just take the first 5 images, not the 5 that are the best match.

[diva dave anthony]

Undefined function or variable "k1".

Error in ==> MONA at 26

for k =[k1,k2,k3,k4,k5]

this is the error coming..

[Walter Roberson]

Assign the index of the smallest value in "g" to k1. Assign the index of the next smallest value in "g" to k2. Assign the index of the third smallest value in "g" to k3. Assign the index of the fourth smallest value in "g" to k4. Assign the index of the fifth smallest value in "g" to k5. Then proceed with the code I showed.

thanx a lot....
