Anatomical Landmark Detection using Deep Appearance-Context Network.

Area of Science:

• Medical Image Analysis
• Deep Learning
• Computer Vision

Background:

• Accurate anatomical landmark identification is vital for medical image analysis.
• Deep neural networks require substantial data, which is often scarce in medical imaging.
• Limited data poses a challenge for training robust deep learning models.

Purpose of the Study:

• To propose an attention-driven end-to-end deep learning architecture for anatomical landmark localization.
• To address the challenge of limited data availability in medical image analysis.
• To improve the stability and performance of deep learning models under data constraints.

Main Methods:
