Natural Scene Braille Character Recognition Dataset
There are a total of 1157 Braille segment images in this dataset, including 925 in the training set and 232 in the testing set. There are two folders in the directory of this dataset: character_label and segment_label. The character_rabel file contains three formats of Braille segment images: (1) Braille segment images and label files stored in ICDAR-2015 format, each. jpg file corresponds to a. txt file, where each line stores the position and recognition label of a braille character rectangle box. The data corresponds to the coordinates of the four points in the rectangle box and the recognized numerical label; (2) The original format of the data is stored in the folder org. Each .jpg file in this folder corresponds to a .json file which marked by labelme software; (3) VOC format, stored in voc-data folder. This folder stores images and corresponding .xml files in VOC format, and marks the position of each braille character rectangle box and its corresponding numerical label information in the .xml file. In addition, the original Braille images of natural scenes and the corresponding Braille segment markings .json files are stored in the folder segment_label.

中国高分辨率高质量PM2.5数据集(2000-2023)
ChinaHighPM2.5数据集是中国高分辨率高质量近地表空气污染物数据集(ChinaHighAirPollutants, CHAP)中PM2.5数据集。该数据集利用人工智能技术,使用模式资料填补了卫星MODIS MAIAC AOD产品的空间缺失值,结合地基观测、大气再分析和排放清单等大数据生产得到2000年至今全国无缝隙地面PM2.5数据。数据十折交叉验证决定系数R2为0.92,均方根误差RMSE为10.76 µg/m3。主要范围为整个中国地区,空间分辨率为1 km,时间分辨率为日、月、年,单位为µg/m3。注意:该数据集持续更新,如需要更多数据,请发邮件联系作者(weijing_rs@163.com; weijing@umd.edu)。 数据文件中包含NC转GeoTiff的四种代码(Python、Matlab、IDL和R语言)nc2geotiff codes。
