DL lies in image-based detection and instance segmentation of an entity, which is a critical issue that needs further investigation. This paper aims to study the fundamental challenges in using object instance segmentation of images. This paper proposes a novel algorithm for multi-object image instance segmentation algorithm in three stages. A novel backbone approach improves the image recognition algorithm by extracting low and high characteristic levels from the given images in the first stage. The ResNet is the fundamental building block and connects with the Squeeze-and-Excitation Network (SENet) for each ResNet block.
