5.CONCLUSION 
The present shadow detection, extraction and 
enhancement methods do not require a DSM or DBM, 
sensor parameters, sun elevation and zenith angle 
parameters in contrast to the previous techniques. The 
mean-shift filtering technique was unexploited in the 
remote sensing image analysis. Further the application of 
the filtering to shadow extraction also new to 
photoeremimeiny: As a future work it is planned to apply 
the method to colour images and also to improve the 
segmentation algorithm to remove false positives.
