<b>ODS1 - Dataset of sputum smear microscopy images for Tuberculosis</b>

<b>ODS1 - Dataset of sputum smear microscopy images for Tuberculosis</b>This dataset was built from 25 sputum smear slides (S) from different selected patients. The sputum samples from patients suspected of being pulmonary TB cases were prepared by the Kinyoun stain method.Two sets of digital field (DF) images were acquired from each slide (S01 to S25). Each set is called Tile Region (TR1 and TR2). Each TR is composed of 164 DF images. From each DF image, 11 images were obtained:one DF image using autofocus microscope function.ten DF images with different focal depth (5 above and 5 below relative to the position of the autofocus image - Z axis).The images acquired are true-color 24-bit image with 1040x1388 pixels. The images were acquired with a Canon PowerShot A640 digital camera, which couples with a 10-megapixel CCD image sensor with a 4× optical zoom. The microscope used was a Zeiss Axioshop 40. A magnification of 100× and a numerical aperture of 1.25 was used.This dataset has 90,200 DF images resulting from 8,200 stacks of 11 images of the same DF image, acquired at different focal depths. The 6th image in the stack is the autofocus image. It was designed to evaluate algorithms for selecting the best autofocusing measurement, and for evaluating image fusion algorithms, for example. Therefore, the bacilli in the images of the data set are not labelled.The folders are individually stored as tar.gz archives, for a total size of 127 GB.

<b>ODS1——肺结核痰涂片显微镜图像数据集</b>
本数据集源自25份来自不同入组患者的痰涂片（编号S01至S25）。针对疑似肺结核患者的痰液样本，采用金胺酚染色法（Kinyoun stain method）进行制片。
每份涂片（S01至S25）均采集两组数字视野（Digital Field, DF）图像，每组命名为Tile Region（TR1与TR2），每个Tile Region包含164张数字视野图像。针对每张数字视野图像，可进一步获取11张子图像：1张为使用显微镜自动对焦功能采集的视野图像，另外10张则以自动对焦图像的Z轴位置为基准，分别在其上下5个不同焦深处采集。
本次采集的图像为24位真彩色图像，分辨率为1040×1388像素。图像采集设备为佳能（Canon）PowerShot A640数码相机，该相机搭载1000万像素CCD图像传感器，支持4倍光学变焦。所用显微镜为蔡司（Zeiss）Axioshop 40型显微镜，采集时采用100倍放大倍率与1.25的数值孔径。
本数据集总计包含90200张数字视野图像，由8200组图像堆叠生成：每组堆叠包含同一张数字视野图像在不同焦深下采集的11张子图像，其中堆叠中的第6张即为自动对焦图像。本数据集的设计初衷为评估最优自动对焦判定算法以及图像融合算法等相关研究场景。因此，数据集中图像内的结核杆菌未进行标注。
数据集文件夹以独立的tar.gz压缩包形式存储，总容量为127GB。
