The BioID Face Database

The BioID Face Database has been recorded and is published to give all researchers working in the area of face detection the possibility to compare the quality of their face detection algorithms with others. It may be used for such purposes without further permission. During the recording special emphasis has been placed on “real world” conditions. Therefore the testset features a large variety of illumination, background, and face size. Some typical sample images are shown below.

Description

===========

The BioID Face Database has been recorded and is published to give allresearchers working in the area of face detection the possibility tocompare the quality of their face detection algorithms withothers. During the recording special emphasis has been laid on "realworld" conditions. Therefore the testset features a large variety ofillumination, background and face size.The dataset consists of 1521 gray level images with a resolution of384x286 pixel. Each one shows the frontal view of a face of one out of23 different test persons. For comparison reasons the set alsocontains manually set eye postions. The images are labeled"BioID_xxxx.pgm" where the characters xxxx are replaced by the indexof the current image (with leading zeros). Similar to this, the files"BioID_xxxx.eye" contain the eye positions for the correspondingimages.

Image File Format

=================

The images are stored in single files using the portable gray map(pgm) data format. A pgm file contains a data header followed by theimage data. In our case the header consists of four lines of text.* The first line describes the format of the image data (ASCII/binary). In our files the text "P5" indicates that the data is written in binary form* The second line contains the image width written in text form * The third line keeps the image height also in text form * The fourth line contains the maximum allowed gray value (255 in our images)The header is followed by a data block containing the image data. Thedata is stored line per line from top to bottom using one byte perpixel.

仿生人脸数据库

BioID人脸数据库已经被记录下来并被发布，以使所有从事人脸检测领域的研究人员能够将他们的人脸检测算法的质量与其他人进行比较。未经进一步许可，可用于此类目的。在录制过程中，特别强调了“真实世界”的条件。因此，测试集具有各种各样的照明、背景和面部尺寸。下面显示了一些典型的示例图像。

说明

===========

BioID人脸数据库已经被记录并发布，以使所有从事人脸检测领域的研究人员能够将他们的人脸检测算法的质量与其他人进行比较。在录制过程中，特别强调了“现实世界”的条件。因此，测试集具有各种各样的照明、背景和面孔大小。这个数据集由1521幅灰度图像组成，分辨率为384x286像素。每一个都显示了23个不同测试人员中一个的正面视图。出于比较原因，设置还包含手动设置眼睛位置。这些图像被标记为“生物”_xxxx.pgm“其中字符xxxx替换为当前图像的索引（带前导零）。与此类似，文件“BioID_xxxx.眼睛包含相应图像的眼睛位置。

图像文件格式

=================

使用便携式灰度图（pgm）数据格式将图像存储在单个文件中。pgm文件包含一个数据头，后跟图像数据。在我们的例子中，标题由四行文本组成。*第一行描述图像数据的格式（ASCII/二进制）。在我们的文件中，文本“P5”表示数据以二进制形式写入*第二行包含以文本形式写入的图像宽度*第三行以文本形式保持图像高度*第四行包含允许的最大灰度值（在我们的图像中为255），标题后面是包含图像数据的数据块。数据从上到下逐行存储，每像素使用一个字节。
