Patent ID: 8175376

Claim:
A method for detecting a region of interest in an image comprising: for each image in a dataset of images for which a region of interest has been established respectively, storing a dataset image representation based on features extracted from the image; for an original image for which a region of interest is to be detected: generating an original image representation for the original image based on features extracted from the image; identifying a subset of similar images from the images in the dataset, the identified subset being based on a measure of similarity between the original image representation and respective dataset image representations; training a classifier with information extracted from the established regions of interest of the subset of similar images, the information for training the classifier comprising at least one of: positive examples, comprising information extracted from patches of the identified similar images that are within the established region of interest, and negative examples comprising information extracted from patches of the identified similar images that are not within the established region of interest; and with the trained classifier, identifying a region of interest in the original image.
