Abstract

Manually identifying similarity between any images is a difficult task. This study proposes an image similarity detection model. The scale-invariant feature transform (SIFT) algorithm is used to detect similarity between input images, and also to calculate the similarity score that defines the extent to which the images are similar. SIFT detects the keypoints and computes its descriptors. A FLANN-based algorithm is used to find the best matches of the descriptors, taking the descriptor of first image and comparing it with the second image. The model achieved 60% accuracy in translational image similarity and 90% in rotational image similarity; feature-matching similarity differed depending upon the given inputs.
