how to recognise an input image from a set of images which contains the input image as one of the images by comparing the pixel values of the input image from that of the set of images??

Hello sir,My problem statement is like this..I need to input an image using imread.In a folder there will be some 20 images.Our input image will b one among the 20 images.Now by comparing the pixel values of the input image with the pixel values of all the 20 images in the folder, i need to recognise that the input image has matched with one of the image in those 20 images.For this first I created a .csv file containing the pixels values of 17 feature points on each face for those 20 images.So now i need to compare the pixel values at the same 17 feature points on the input image with the pixel values of those 20 images in the.csv file.And then find a match that input image is present in those 20 images..how to do the comparison of pixel values is my problem..can any one help me plz...??
