Introduction #
The Water Meters Dataset comprises a wide array of images depicting water meters, complete with associated segmentation masks and OCR labels for meter readings. The data was collected using Yandex.Toloka. Please note that this description is just a sample of the data. For comprehensive information, refer to the dataset’s homepage.
Summary #
Water Meters Dataset is a dataset for semantic segmentation and object detection tasks. It is used in the utilities industry.
The dataset consists of 1244 images with 1244 labeled objects belonging to 1 single class (water meter data).
Images in the Water Meters dataset have pixel-level semantic segmentation annotations. All images are labeled (i.e. with annotations). There are no pre-defined train/val/test splits in the dataset. The dataset was released in 2020 by the TrainingData.pro, UAE.
