Hello everyone i want to retrieve images based on the euclidean distance.How to get euclideans distance from feature vector and sort images and display

How about using the formula for Euclidean distance:

meanDistance = sqrt(sum((featureVector - referenceFeatureVector).^2));

thank you.but how to calculate distance between two imags

How are you defining that? I answered your original question of how to find unweighted distance between two feature vectors. How are you defining distance between two images, rather than feature vectors? Do you mean the MSE? Or PSNR? Or SSIM? Or something else????
