|| 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"?

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)

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?
