Tagged images with bees 3

Images taken from bee hive with tagged bees. The images are random frames from movies recorded in may 2017 and 2018. All images are taken from full HD video stream. The images filenames are the same as filename of source video, so it should be easy to match. Labels inside each file follow a name convention:e.g. rawdata/DSCN9958_segment_007_frame_210_scale_0_8.bmp means that:* video filename is DSCN9958* segment number is 7 (it's 8th frame chosen from this video, numbers start from 0)* frame number is 210 (it's 211th frame of all frames in this video, numbers start from 0)* scale of tagged video is 0.8 ("_" instead of "."), to use labels for full scale videos, you need to unscale the labels The tagging of the images was done manually using objectmaker.exe tool (supplied with the part 1 of the data, see references). The tags are stored in text files with names identical as the movie filename and has the following format: "image_name number_of_tags x_coordinate_of_top_lef_corner y_coordinate_of_top_lef_corner x_coordinate_of_bottom_right_corner y_coordinate_of_bottom_right_corner". The coordinate set is provided number_of_tags times.

本数据集的图像均采集自蜂箱内的标记蜜蜂。图像源自2017年5月与2018年5月录制的视频，取其随机帧，全部来自全高清视频流。图像文件名与源视频文件名完全一致，可轻松实现二者的对应匹配。各文件内的标签遵循如下命名规范：以rawdata/DSCN9958_segment_007_frame_210_scale_0_8.bmp为例，其含义为：* 对应视频文件名为DSCN9958；* 片段编号为7（即从该视频中选取的第8帧，编号从0开始计数）；* 帧编号为210（即该视频总帧序列中的第211帧，编号从0开始计数）；* 标记视频的缩放比例为0.8，命名中使用下划线替代了小数点；若需将标签适配至原比例视频，需对标签进行反缩放处理。本数据集的图像标注通过objectmaker.exe工具手动完成，该工具随数据集第一部分一并提供，详见参考文献。标签存储于与对应视频文件名完全同名的文本文件中，格式为："图像文件名 标签数量 左上角x坐标 左上角y坐标 右下角x坐标 右下角y坐标"，其中坐标集将按照标签数量重复输出。
