Follicle Segmentation from ovarian USG image using Horizontal Window Filtering and Filled Convex Hull Technique

EasyChair Preprint 2608

Abstract

In this paper a segmentation technique has been developed and discussed to segment different follicles from ultrasound image. The proposed segmentation technique used a 20 pixel long window and standard deviation of the USG image for smoothing and despeckling the image. Further, morphological opening followed by morphological closing operations have been applied to the image for removing the paper and salt noise. Next, segmentation of the follicles is done by finding the active contours and filled convex hull from the intermediate USG image that contains only the follicles those are bright i.e. white in color with a black background. Finally, a comparative study has been presented between the experimental results and inferences made by the experts to validate the results towards determining the degree of accuracy of the proposed technique.
