Hi @Sirisha Golukonda,

For effective segmentation, it is better to use Deep Learning techniques.

Please refer to the below links, which will give you an overall idea of using U-Net for semantic segmentation.

This example uses a 3-D pretrained U-Net for segmentation. You can also try using different models for effective segmentation.

One such model is "DeepLab v3+". It uses atrous (or dilated) convolutions, which allow the network to capture multi-scale contextual information without losing resolution. This is particularly useful for segmenting objects at various scales.

For more information on how to train a segmentation model using “deeplabv3plus” refer to the following link.
