Epipolar resampling aims to eliminate the vertical parallax of stereo images. Due to the dynamic nature of the exterior orientation parameters of linear pushbroom satellite imagery and the complexity of reconstructing the epipolar geometry using rigorous sensor models, so far, no epipolar resampling approach has been proposed based on these models. In this paper for the first time it is shown t...

We present a new approach to camera calibration as a part of a complete and practical system to recover digital copies of sculpture from uncalibrated image sequences taken under turntable motion. In this paper we introduce the concept of the silhouette coherence of a set of silhouettes generated by a 3D object. We show how the maximization of the silhouette coherence can be exploited to recover...

We present a geometric approach for the analysis of dynamic scenes containing multiple rigidly moving objects seen in two perspective views. Our approach exploits the algebraic and geometric properties of the so-called multibody epipolar constraint and its associated multibody fundamental matrix, which are natural generalizations of the epipolar constraint and of the fundamental matrix to multi...

This paper presents image-based rendering related techniques; (1)a computer vision technique to estimate accurate epipolar geometry and (2) a n image coding technique to compress multiple-viewpoint images, which are stored for reconstruction of any arbitrary view of 3-0 object, with the epipolar geometry. Uhlike other epipolar geometry estimation techniques based o n the correct sets of feature...

This paper addresses the epipolar geometry of linear pushbroom imagery. Two images of a single scene are related by epipolar geometry which contain all geometric information and is essential for the three dimensional reconstruction of the scene in computer vision and remote sensing. It is told that the epipolar geometry of the linear pushbroom sensor is different from that of the perspective on...

Normalized image generation (epipolar resampling) is an important task for automatic image matching. Normalized images facilitate the detection of feature correspondences in the images and therefore provide the advantages of reducing the search space as well as the matching ambiguities. Normalized image generation is a well-established procedure for images captured by frame cameras. Digital fra...

This paper presents a practical epipolarity model for high-resolution linear pushbroom satellite images acquired in either along-track or cross-track mode, based on the projection reference plane in object space. A new method for epipolar resampling of satellite stereo imagery based on this model is then developed. In this method, the pixel-to-pixel relationship between the original image and t...

The Crossed-Slits (X-Slits) camera is defined by two nonintersecting slits, which replace the pinhole in the common perspective camera. Each point in space is projected to the image plane by a ray which passes through the point and the two slits. The X-Slits projection model includes the pushbroom camera as a special case. In addition, it describes a certain class of panoramic images, which are...
