This study introduces a new Object Information based Interactive Segmentation (OIIS) method for extracting gastric fatty tissues. OIIS simplifies the process by only requiring object information, proving effective in experiments.

Area of Science:

Medical Imaging
Computer-Aided Diagnosis
Surgical Pathology

Background:

Lymph node status is crucial for gastric cancer diagnosis.
Extracting complex gastric fatty tissues is challenging for automated and manual methods.
Current interactive segmentation methods often require both object and background information.

Purpose of the Study:

To propose a novel semi-automatic segmentation method requiring only object information.
To address the limitations of existing interactive segmentation techniques in medical imaging.
To improve the efficiency of gastric fatty tissue extraction for clinical diagnosis.

Main Methods:

Development of the Object Information based Interactive Segmentation (OIIS) method.
OIIS requires only user input for object features, excluding background information.

Keywords:

Fatty tissue Gastric cancer Interactive image segmentation Mean shift Object information
