Structure and motion from straight line segments

Structure and motion from straight line segments

A method to determine both the camera location and scene structure from im age straight segment correspondences is presented The proposed method considers the nite segment length in order to use stronger constraints than do those that use the in nite line that supports the image segment The constraints between image segments involve a weak pairing between image segment midpoints This al lows de...

Structure and Motion from Line Segments inMultiple

| This paper presents a new method for recovering the three dimensional structure of a scene composed of straight line segments using the image data obtained from a moving camera. The recovery algorithm is formulated in terms of an objective function which measures the total squared distance in the image plane between the observed edge segments and the projections (perspective) of the reconstru...

Structure and motion from line segments in multiple images

|This paper presents a new method for recovering the three dimensional structure of a scene composed of straight line segments using the image data obtained from a moving camera. The recovery algorithm is formulated in terms of an objective function which measures the total squared distance in the image plane between the observed edge segments and the projections (perspective) of the reconstruc...

A neural network structure for detecting straight line segments

A new method for detecting one-pixel wide vertical, horizontal and diagonal line segments in binary images, is presented. It is based on using four slabs of neural networh, each of which is composed of a set layers. Each layer consists of a number of neurons that is determined by the slab type. The whole image is used as input to each slab, and the infomation processing in each slab occurs in p...
