Abstract
A method representing an object appearing in still or video image for use in searching, wherein the object appears in the image with a first two-dimensional outline, by processing signals corresponding to the image, comprises deriving a view descriptor of the first outline of the object and deriving at least one additional view descriptor of the outline of the object in a different view, and associating the two or more view descriptors to form an object descriptor.
Claims11
A method of representing an object appearing in an image using one or more processors, the method comprising:
- deriving, using a processor, a plurality of view descriptors of the object, each view descriptor corresponding to a different view of the object;
- associating, using a processor, the view descriptors to form an object descriptor, wherein at least one view descriptor comprises a representation of the colour or texture of the object in the respective view;
- and
- identifying the object in the image, and identifying a first view of said object;
- determining the colour or texture of said object in said first view and therefrom deriving a colour first view descriptor or a texture first view descriptor;
- identifying another image of the object, showing the object in a second view, different from the first view;
- determining the colour or texture of said object in said second view, and therefrom deriving a colour second view descriptor or a texture second view descriptor;
- and
- associating at least said colour first view descriptor and said colour second view descriptor, or at least said texture first view descriptor and said texture second view descriptor, to form a colour multiview object descriptor or a texture multiview object descriptor.
A method of representing an object appearing in a group of images using one or more processors, the method comprising:
- deriving, using a processor, a plurality of view descriptors of the object, each view descriptor corresponding to a different view of the object;
- associating, using a processor, the view descriptors to form an object descriptor, wherein at least one view descriptor comprises a representation of the colour or texture of the object in the respective view;
- and
- identifying the object in the image, and identifying a first view of said object;
- determining the colour or texture of said object in said first view and therefrom deriving a colour first view descriptor or a texture first view descriptor;
- identifying another image of the object, showing the object in a second view, different from the first view;
- determining the colour or texture of said object in said second view, and therefrom deriving a colour second view descriptor or a texture second view descriptor;
- and
- associating at least said colour first view descriptor and said colour second view descriptor, or at least said texture first view descriptor and said texture second view descriptor, to form a colour multiview object descriptor or a texture multiview object descriptor.
A method of indexing images or groups of images stored in a database using one or more processors, the method comprising:
- identifying an object appearing in an image or group of images;
- deriving, using a processor, representations of a plurality of different views of the object;
- associating, using a processor, the view descriptors to form an object descriptor, wherein at least one view descriptor comprises a representation of the colour or texture of the object in the respective view;
- and
- identifying the object in a first image in the group of images, and identifying a first view of said object;
- determining the colour or texture of said object in said first view and therefrom deriving a colour first view descriptor or a texture first view descriptor;
- identifying another image of the object, showing the object in a second view, different from the first view, which may or may not be a second view in a second image in the group of images;
- determining the colour or texture of said object in said second view, and therefrom deriving a colour second view descriptor or a texture second view descriptor;
- and
- associating at least said colour first view descriptor and said colour second view descriptor, or at least said texture first view descriptor and said texture second view descriptor, to form a colour multiview object descriptor or a texture multiview object descriptor.
