Abstract :
The paper presents a method for detecting linear features in a satellite image. For enhancing these features, a local operation based algorithm is proposed which uses a certain multiplicative score rather than the commonly used additive score. The main contribution is in segmenting the linear features in the enhanced image where an adaptive segmentation technique is proposed on the basis of statistical models. A robust parameter estimation is done for this purpose
