how can i get the indexes

|| I am working in CBIR by histogram color my prof just wants to test me if i understand it or no so it is not my final project

now I have file has 161 images inside and I have 10 query images

I have extracted histogram color for the images files and i put them in vectory then I compute Euclidean distance for each images for query image and images file and i put them all in vectory so now I have 10*161 .until here is my work is good ?? then now if I sort the vectory ok how could i get the reall index for the images have smallest Euclidean distance , I try to do this

[x, y] = sort[vectory4] and then take the index but it gave me the first 10 images in database not that i want .

hope anyone help me .

thank you ||*

It is hard to estimate if "I have 10*161" is correct or not. Actually "10*161" is 1610, but you certainly mean a matrix. Afterwards you are looking for a kind of sorting. But what is "vector4"?

[shima said]

"vector4" it is a vector where i put the result of compute Euclidean distance

Did you look at the min function?

% Generate sample data.
array10by161 = randi(1000, [10, 161]);
% Find min distance for each image (each row)
% and it's location (column number)
[minDistances, indexOfMin] = min(array10by161, [], 2)

thank you so much ^Image Analyst^ it works good now

but it just show me 10 retrieval image how could i make it show for example 20 I meant indexOfMin has just 10 values inside it

You said "i put them all in vectory so now I have 10*161" so just do the same thing but for 20, or however many you want, instead of 10.

I tried that early before I asked you here but it still has just 10 values

[Image Analyst]

Well then, you're not building up your array properly. Isn't the row number the number of the image that you processed? So results from image #11 should have gone into row #11?

[shima said]

yes each row for one query image so 10 rows * 161 Columns

let me explain more i meant the 10 queries image ok , in my database there is others images are similar to them so for example q1 have 4 similar images so i want to show all them for each image . hope u understand me . ur answered worked good but it just show me 10 images i need more .
