A system and method are provided for segmenting an image. The method includes computing (S204) an image signature for an input image. One or more similar images are identified (S201) from a first set of images, based on the image signature of the input image and image signatures of images in the first set of images. The similar image or images are used to define (S212) a cropped region of the input image and a second image signature is computed, this time for the cropped region (S214). One or more similar images are identified (S218) from a second set of images, based on the cropped image signature and the image signatures of images in the second set of images. The input image is segmented (S222) based on a segmentation map of at least one of the similar images identified in the second set of images. |
