DBrasiliensis

The DBrasiliensis dataset is a repository with 246 images containing 5141 cysts of Dendrocephalus brasiliensis, a native species from South America. The cyst examples were obtained from substrates portions took from the bottom of an aquarium used as an incubator and split into two parts: one to capture the training images and the other to capture the test images. Training images: the substrate was fixed on white coverslips and observed under a XTRAD USB digital microscope model XT-2036, in which the images were captured using 52x objective lenses. Subsequently, the LabelImg software was used to label cysts in both PASCAL VOC and YOLO formats. There are 111 images in all for training with a resolution of 640x480, containing 3173 annotated cysts. Test images: the testing set was built with the aim of assigning a weight to a set of images. The substrate was split into small portions on a white coverslip and weigh it using a precision scale. Then, we capture an image of each portion of the substrate using the digital microscope. The captured images were stored in a folder, whose name indicates the amount of cyst and the weight of the substrate contained in the set of images. Besides, the file name of each image in the folder indicates the image number and amount of cyst contained in it. The complete testing set has 1968 cysts in 135 images with a resolution of 640x480 distributed in 10 folders. The substrate weight used to build the testing set is 4.24 grams.DBrasiliensis数据集（DBrasiliensis Dataset）是一个包含246幅图像的样本库，内含共计5141枚巴西枝额虫（Dendrocephalus brasiliensis）的休眠卵囊，该物种为南美本土特有物种。这些休眠卵囊样本取自用作孵化箱的水族箱底部的基质样本，并被划分为两部分：一部分用于采集训练集图像，另一部分用于采集测试集图像。 训练集图像：将基质固定于白色盖玻片上，使用型号为XT-2036的XTRAD USB数码显微镜进行观测，并通过52倍物镜采集图像。随后采用LabelImg软件，以PASCAL VOC与YOLO两种格式对休眠卵囊进行标注。训练集总计包含111幅分辨率为640×480的图像，共计标注了3173枚休眠卵囊。 测试集图像：本次测试集的构建旨在为各图像子集关联对应的基质重量参数。将基质在白色盖玻片上分割为若干小份，随后使用精密天平称量每份基质的重量。之后使用前述数码显微镜采集每份基质小份的图像。所采集的图像存储于单个文件夹中，文件夹名称会标注该集合内所含休眠卵囊数量与基质重量；而文件夹内单幅图像的文件名则会标注图像序号与该图像内包含的休眠卵囊数量。完整测试集包含135幅分辨率为640×480的图像，共计1968枚休眠卵囊，被划分至10个文件夹中。用于构建该测试集的基质总重量为4.24克。
