摘要：This paper deals with effect of image gradients as initial step for"watershed segmentation" .Watershed transformation is a common technique for image segmentation. Effects of gradients are studied in the presence of different operators and further these operators are used to segment the image by watershed transformation. Convolution is performed using different mask operations. The purpose is to identify the operator which gives better results as initial step for watershed approach and the effect is studied in terms of time and peak signal to noise ratio
