Feature Tensor Low-Rank Representation Network for Semi-Supervised Echocardiography Video Left Ventricle Segmentation.

As a non-invasive and real-time diagnostic method, echocardiography plays a crucial role in assessing heart health and diagnosing disease. Accurate segmentation of echocardiography videos is essential for understanding cardiac structure and function. However, it encounters several challenges, including the presence of speckle noise, low image contrast, and incomplete video annotations.
