Abstract: A mark-free computer-assisted diagnosis method and system are provided for assisting diagnosis of abnormalities in digital medical images using diagnosis based image enhancement. The method includes the steps of: receiving indicia identifying one or more regions of interest in a digital medical image; and displaying one or more enhanced views of the regions of interest, the enhanced views being based on diagnostic parameters for the regions of interest and diagnostic parameters corresponding to a particular abnormality.

Abstract: A computer-assisted diagnosis method and system are provided for automatically determining diagnostic saliency of digital images. The method includes the step of providing filters for evaluating the image. Each filter is designed to identify a specific type of diagnostic finding, and is associated with the following: a virtual window for defining regions in the image at which the filter is applied; a set of training image patches corresponding to typical appearances of the specific type of diagnostic finding; a distance measure between the training image patches and the regions in the image defined by the virtual window; and a feature set corresponding to the distance measure. The filters are applied to the image to compute distances between the regions in the image defined by the virtual window and the training image patches based on the distance measure and the feature set, for each of the plurality of filters.
