Automated designation of tie-points for image-to-image coregistration

Automated designation of tie-points for image-to-image coregistration

Image-to-image registration requires identification of common points in both images (irnage tie-points: ITPs). Here. we describe software implementing an automated, area-based technique for identifying ITPs. The ITP software was designed to follow two strategies: ( I ) capitalize on human knowledge and patternrecognition strengths, and (2) favour robustness in many situations over optimal perfo...

Image Coregistration in Sar Interferometry

A critical procedure in Synthetic Aperture Radar (SAR) Interferometric (InSAR) processing was studied: SAR image coregistration. Two pairs of ERS-1/2 SAR tandem data, representing diverse terrain types and different baselines, were used in this research. The commonly used traditional SAR image coregistration algorithms were addressed and tested; the computationally intensive algorithms were exa...

New Method for Analysis of image sensor to produce and evaluate the image

In this paper, a new method for evaluating CMOS image sensors based on computer modeling and analysis is introduced. Image sensors are composed of different parts, each of which has a specific effect on image quality. Circuits of image sensors can be evaluated and analyzed using circuit simulators or theoretically, but these methods cannot help to produce the final image. In order to produce th...

Precise Orientation of Spot Panchromatic Images with Tie Points to a Sar Image

The extraction of spatial data from satellite imagery requires that precise sensor models are used to orientate images. This is particularly important with images acquired by linear sensors, such as SPOT, frequently pointed with large incidence angles. Image orientation with pixel accuracy requires that accurate ground control points are used. The acquisition of ground control is especially dif...
