Need Guidence- DL/CV project

Hi everyone! I’m new to Artificial Intelligence and Computer Vision and could use some guidance. I have a task that involves instance segmentation, but I’m facing an issue where the objects are overlapping, leading to inaccurate or incorrect detections. What approaches or techniques can I use to overcome this problem? Any help would be greatly appreciated!

Have you attended Course 4 of the Deep Learning Specialization? It covers this topic.
