Extended heartSeg

这项工作的数据集 X 是 heartSeg 数据集的扩展。每个样本 x ∈ X 是一个 RGB 图像，从恒定的腹侧视图捕获 Medaka (Oryzias latipes) 幼体的心脏区域。由于青鳉的身体是透明的，因此可以对内脏和整个循环系统进行无创研究。青鳉的心脏包含三个部分：心房、心室和球部。心房接收来自循环系统的脱氧血液并将其输送到心室，心室将其转发到球部。球茎是心脏的出口腔，为鳃弓提供恒定的血流。总共在 63 个短记录中捕获了流经这三个腔室的血流（大约 11 秒，每个记录 24 帧/秒），从中提取单个图像样本 x ∈ X。数据集按照 heartSeg 数据集分为训练和测试数据，训练集 Xtrain 中的 ntrain = 565 个样本，测试集 Xtest 中的 ntest = 165 个样本。 RGB 图像样本的分辨率为 640 × 480 像素。The dataset X in this work is an extension of the heartSeg dataset. Each sample x ∈ X is an RGB image capturing the heart region of larval *Medaka (Oryzias latipes)* from a consistent ventral view. As the body of Medaka is transparent, non-invasive studies of their viscera and entire circulatory system are feasible. The heart of Medaka consists of three compartments: the atrium, ventricle, and bulbus arteriosus. The atrium receives deoxygenated blood from the circulatory system and delivers it to the ventricle, which then passes the blood to the bulbus arteriosus. The bulbus arteriosus is the outlet chamber of the heart, providing constant blood flow to the gill arches. Blood flow through these three cardiac chambers was captured in a total of 63 short recordings (approximately 11 seconds each, at 24 frames per second), from which individual image samples x ∈ X were extracted. The dataset is split into training and test subsets following the split protocol of the heartSeg dataset: there are ntrain = 565 samples in the training set Xtrain and ntest = 165 samples in the test set Xtest. The resolution of each RGB image sample is 640 × 480 pixels.
