In this paper, a fast geometric rectification method for space-borne SAR (Synthetic Aperture Radar) digital image in slant range with no ground control point is introduced , which is based on the imaging principle of SAR and the law of geometric distortion in slant range image. The main idea is at first to resample a slant range SAR image to a ground range image with a definite ground spacing b...

A novel ortho-rectification approach for satellite imagery, which we name the ‘three-model approach’, is proposed. Rather than fitting a single model, as is typically done, this approach fits a sequence of three models. The first model estimates the azimuth of the image, the image scaling factor and image shifting; the second model estimates the overall image pitch/shearing angle; and the third...

this paper presents, a hybrid method, low-resolution and high-resolution, for persian page segmentation. in the low-resolution page segmentation, a pyramidal image structure is constructed for multiscale analysis and segments document image to a set of regions. by high-resolution page segmentation, by connected components analysis, each region is segmented to homogeneous regions and identifying...

This paper describes a method for stereoscopic rectification with geometric distortion minimisation, to generate suitable image pairs for 3D viewing applications. The current state of the art technique is not optimal as it lacks appropriate mathematical constraints. We present a new approach that enforces the same distortion minimisation criterion with more computational efficiency whilst also ...
