Ridge Counting FVC 2002 DB1A

The proposed ridge count dataset is derived from the publicly available FVC-2002-DB1A benchmark [38]. FVC-2002-DB1A images were captured at a resolution of 500 dpi with dimensions of 388 × 374 pixels using the Identix TouchView II optical sensor. We annotated a subset consisting of the first two fingerprint samples from each of the initial 50 subjects, totaling 100 images.

本研究提出的脊纹计数数据集源自公开可得的FVC-2002-DB1A基准数据集[38]。该数据集的图像采用Identix TouchView II光学传感器采集，分辨率为500 dpi，图像尺寸为388×374像素。本研究对初始50名受试者各提供的前两份指纹样本组成的子集进行了标注，总计得到100张图像。
