Abstract :
A qualitative analysis of the effects of noise, foreshortening, and photometric variations on cepstral correspondence methods is presented. A modified approach that is less sensitive to these effects is developed, and analytical arguments for its robustness are given. The performance of the improved method is experimentally verified on real data
