A Survey on Finding Image Similarity and Retrieval of Near Duplicate Images

computer Engineering

The image can be modified using some transformation and scaling on original images which forms near duplicate images. An image can be represented by their size or length and the number of patches in the image varies with respect to the length. The adjacent and visually same pixels are clustered or grouped and then the resulting cluster is considered as a patch. Image representation and image similarity measurement are two major issues in image matching. The proposed method extracts patches from given image and represents by changeable length signature. The signature is further verify and validated in a near duplicate natural image detection which makes a decision about whether two images are near duplicates or not. The near duplicate image retrieval aims at retrieving relevant or same images from image database which are similar to query image. The similarity between two images is finding by Using Earth Move Distance Algorithm.
