Abstract
Systems and methods are provided for editing an image of a vehicle interior to isolate the occupant of a vehicle seat. An image generator (102) generates an image of a vehicle interior. A contour generator (104) produces a contour image from the generated image. A model selector (106) selects a contour model from a plurality of contour models according to the similarity of the contour model to a portion of the contour image. An image editor (108) removes a portion of the generated image representing at least a portion of the vehicle seat according to the selected contour model to produce an image of an occupant of the vehicle seat.
Claims22
A method for preprocessing an image of a vehicle interior to remove a portion of the image corresponding to a seat back comprising:
- generating a contour image from the image;
- selecting one of a plurality of contour models that most closely matches the generated contour image, a given contour model being associated with one of a plurality of possible seat positions;
- determining a plane of separation between a seat back and a seat occupant within the image based on the selected contour model;
- and
- removing a portion of the image corresponding to the seat back based on the determined plane of separation to isolate an image of the seat occupant.
A system for editing an image of a vehicle interior to isolate the occupant of a vehicle seat comprising:
- an image generator that generates an image of a vehicle interior;
- a contour generator that produces a contour image from the generated image;
- a model selector that selects a contour model from a plurality of contour models according to the similarity of the contour model to a portion of the contour image;
- and
- an image editor that removes a portion of the generated image representing at least a portion of the vehicle seat according to the selected contour, model to produce an image of an occupant of the vehicle seat.
A computer program product, implemented in a computer readable medium and operative in a data processing system, for editing an image of a vehicle interior to isolate the occupant of a vehicle seat comprising:
- a contour generator that produces a contour image from one or more generated images;
- a model selector that selects a contour model from a plurality of contour models according to the contour image and an associated selection algorithm;
- and
- an image editor that edits the generated image to remove a portion of the image representing the vehicle seat according to the selected contour model.
