Abstract: In general, imaging analysis of fetal heart images through concave region newlineclusters the image with respect to time and frequency domain. The clustering is carried newlineout through optimization algorithms that reduces the error in images and delineate newlinethem with high accuracy. The high accuracy of images in turn leads to high contrast in newlinefetal heart images. Moreover, the fetal heart image is clustered and quantified with newlineground truth verification rule. In this research work, the fetal heart image is optimized newlinethrough nature inspired algorithms such as GA, FCM, PSO, CSO and FFO clustering newlinein the solution space. newlineThe genetic algorithm clusters the fetal heart image through concave region newlineand delineate the pixel with high accuracy and GA clusters through the population of newlinenature inspired algorithm. The GA finds the fitness or intensity of the pixel through the newlinepopulation in the solution space and finds suggested size, shape and intensity in the newlinesolution space. Finally, the algorithm improves the overall accuracy through the newlineconcave region in the feasible solution space. newlineThe FCM method cluster the fetal heart image with size and shape through the newlineconcave region. The clustered fetal heart image is optimized in the solution space. newlineThe fuzzy c-means clustering algorithm delineate the pixel with high contrast and also newlinefinds the edge detection in the fetal heart image. The overall accuracy of clustered newlinefetal heart image is about 70%. The c-means clustering algorithm also analyses the newlineedge and boundary. newlineThe edge and boundary detection of fetal heart image using the particle swarm newlineoptimization algorithm is proposed in the present research work. The approach newlineidentifies the centroids of clusters that are normally in user specified numbers with newlinesimilar image features and every cluster groups together. The proposed algorithm is newlinevalidated for broad applicability using MRI and synthetic images of fetal heart.
