A Deep Learning Approach for Predicting Subject-Specific Human Skull Shape from Head Toward a Decision Support System for Home-Based Facial Rehabilitation

چکیده

Prediction of human skull shape from head is a complex and challenging engineering task for the development computer-aided vision system. Skull-to-face generation has been commonly performed in forensic facial reconstruction. Classical statistical approaches were usually used. However, head-to-skull relationship still misunderstood. Recently, novel deep learning (DL) models have showed their efficiency robustness large range applications. The present study aimed to develop approach based on reconstruct head. A workflow was developed evaluated. database computed tomography (CT) images 209 subjects established training testing purposes. Three-dimension (3-D) geometries reconstructed then respective descriptors (head/skull volumes, sampling feature points point-to-center distances, head-skull thickness, Gaussian curvatures) extracted. Two (regression neural network long-short term memory (LSTM)) implemented evaluated with different configurations. 10-fold cross-validation performed. Finally, best worst predicted cases analyzed discussed. mean errors better accuracy level regression model according long short-term model. error between DL-predicted shapes CT-based ranges 1.67 mm 3.99 by using configuration. volume deviation smaller than 5%. suggested that allows be given good accuracy. This opens new avenues rapid visual sensors (e.g. Microsoft Kinect) toward system mimic rehabilitation. As perspectives, muscle will incorporated into workflow. Then, movements tracked animated evaluate optimize rehabilitation exercises. • Predicting subject-specific automatically shape. Feature relationship. 3D geometries.

Deep learning-based CAD systems for mammography: A review article

Breast cancer is one of the most common types of cancer in women. Screening mammography is a low‑dose X‑ray examination of breasts, which is conducted to detect breast cancer at early stages when the cancerous tumor is too small to be felt as a lump. Screening mammography is conducted for women with no symptoms of breast cancer, for early detection of cancer when the cancer is most treatable an...
