Record 7 2007-01-31

English

Subject field(s)
  • Remote Sensing
DEF

A technique used in image restoration, enhancement or coding [that is] a separable orthogonal transform or an expansion of the matrix in rank-1 matrices.

CONT

This paper presents a simple and effective method for matching two uncalibrated images. Corner points are firstly extracted as interest points in the two images. Each interest point is assigned one dominant orientation. The initial set of point matches is then obtained by singular value decomposition of a correspondence strength matrix. A new expression of this matrix is introduced to handle more complicated imaging conditions. Each element of this matrix is the similarity measure between two interest points. The new similarity measure is invariant to image rotation by taking into account the dominant orientation of the two interest points. The epipolar geometry constraint is finally imposed to reject the false matches. Experimental results on real images show this approach to be effective for general image matching.

Photo-Optical Binary Code Systems: Particularly adaptable to random files, binary code systems depend on an organized code for retrieval, such as an invoice number, customer number or customer name, instead of an external index.

OBS

Photo-optical coding places descriptive data related to documents in photo-optical format on the film. The coding is placed either adjacent to the document frame or along the edge of the film.... The coding is created through a keyboard associated with a microfilm camera or by filming precoded information simultaneously with the document or by COM [computer-output microfilm] with the appropriate software. A search is conducted by keying in the codes. The film code patterns are electronically scanned, and the film stops at the image or images identified by the desired matching codes.
