Method and apparatus for searching images

摘要

Disclosed are methods and apparatuses for searching images. An image is received and a first search path is defined for the image. The first search path may be a straight line, horizontal, and/or near the bottom of the image, and/or may begin at one edge and move toward the other. A transition is defined for the image, distinguishing a feature to be found. The image is searched for the transition along the first search path. When the transition is detected, the image is searched along a second search path that follows the transition. The apparatus includes an image sensor and a processor. The sensor is adapted to obtain images. The processor is adapted to define a first search path and a transition for the image, to search for the transition along the first search path, and to search along a second search path upon detecting the transition, following the transition.

1. A computer-implemented method comprising:
receiving, at a processor, an image; defining a first search path for said image; defining a transition for said image; searching for said transition along said first search path; and upon detecting said transition, searching along a second search path, said second search path substantially following said transition; wherein in searching along said second search path, following said transition in at least two directions.
