Abstract
A computerized method for annotating at least one feature of an image of a view, includes the steps of obtaining the image with an image sensor of a portable device, and retrieving at least one condition. Based on the at least one condition, the method automatically selects a feature identification method among a plurality of features identification methods. It then applies the feature identification method for identifying the at least one feature, and annotates some of the identified features.
Claims10
A computerized method for annotating at least one feature of an image of a view, comprising:
- capturing the image with an image sensor of a portable device;
- selecting, with a processor of the portable device, a feature identification method from a plurality of available feature identification methods based on a focusing distance, wherein the focusing distance indicates a foreground focus or a background focus on an object in the image, and wherein said plurality of feature identification methods comprises:
- a first feature identification method matching features of said image with one or more of a plurality of 2D reference images that is selected when said focusing distance indicates background focus on the object in the image,
- a second feature identification method matching features of said image with projections of one or more of a plurality of 3D models that is selected when said focusing distance indicates foreground focus on the object in the image, or
- a combination thereof;
- applying, with the processor of the portable device, said feature identification method for identifying a plurality of features of said image, and deciding which of said identified features of said image are to be annotated;
- annotating, with the processor of the portable device, at least some of the identified features, resulting in an annotated image with superimposed annotations;
- and
- displaying the annotated image with the superimposed annotations on a display of the portable device.
A computer-readable non-transitory storage medium encoded with instructions for causing a programmable processor to perform a method, comprising:
- capturing an image with an image sensor of a portable device;
- selecting a feature identification method from a plurality of available feature identification methods based on a focusing distance, wherein the focusing distance indicates a foreground focus or a background focus on an object in the image, and wherein said plurality of feature identification methods comprises:
- a first feature identification method matching features of said image with one or more of a plurality of 2D reference images that is selected when said focusing distance indicates background focus on the object in the image,
- a second feature identification method matching features of said image with projections of one or more of a plurality of 3D models that is selected when said focusing distance indicates foreground focus on the object in the image, or
- a combination thereof;
- applying the selected feature identification method for identifying a plurality of features of said image, and deciding which of said identified features of said image are to be annotated;
- annotating at least some of the identified features, resulting in an annotated image with superimposed annotations;
- and
- displaying the annotated image with the superimposed annotation on a display of the portable device.
