Estimating Vanishing Points in Images
First Claim
1. An automated image processor arranged to receive original digital image data and estimate the position of a vanishing point in an image plane of a respective original digital image, including by detecting pairs of similar image patches within an image and identifying a concurrent set of straight virtual lines that substantially converge at a point on the image plane, each line passing through a pair of similar image patches within the image.

Abstract
A digital image is processed to provide an estimation of the position in the image plane of a vanishing point. The processing includes detecting pairs of similar image patches and identifying a concurrent set of straight virtual lines that substantially converge at a point on the image plane, each line passing through a pair of similar image patches within the image.

20. An image processor comprising:
-
a. an input to receive digital data representing a digital image; b. a data store to store a received digital image; and c. a vanishing point estimator, which is adapted to estimate the position of a vanishing point in an image plane of a digital image, including by detecting pairs of similar image patches within an image and identifying a concurrent set of straight virtual lines that substantially converge at a point on the image plane, each line passing through a pair of similar image patches within the image.
