Abstract:
The present disclosure discloses a method for retrieval of similar images from a database. For a plurality of input images, each input image is disintegrated into a plurality of image patches of one or more predefined pixel sizes. A representation of each image patch is computed using a dimensional reduction method and distances between the representations of each image patch are compared. Further, the representations of each image patch into addressable hyper-cubes are quantized, wherein an address of a hyper-cube is determined by content of corresponding image patch. Then, each image patch is stored using corresponding address as a key into the database. Later, for a target image patch, a set of similar image patches is retrieved from the database using the key.
