人脸识别中的Training set, Gallery set 和 Probe set

本文详细解读了步态识别中Galleryset(人脸库)与Probeset(待验证库)的概念,涉及它们在训练、验证过程中的作用,以及如何通过距离计算进行人脸匹配。

步态识别中Probe Set和Gallery Set的理解


  • 之前看人脸识别相关的paper的时候,出现了这些名词,所以记录一下;
  • 如果有不对的地方,还希望批评指正。

  • Training set:训练模型用的数据集;
  • Gallery set: ground- truth的人脸库,用来与Probe set中的人脸图比对;
  • Probe set:待验证的人脸库,与Gallery set的人脸库比对,跟Gallery set的人脸库中哪张人脸的距离(余弦距离、欧氏距离等)近,就是哪张人脸;
  • 注:Training set、Gallery set和Probe set中的图,两两之间互不重复。
Surveillance Face Recognition Challenge # ======================== Dataset Structure ========================== # "Training_Set": Ordered by face identities, i.e. each directory contains face images from a specific training identity. There are a total of 5,319 directories each is named by the corresponding identity. The image file name is in format of [PersonID]_[CameraID]_[ImageName].jpg. "Face_Identification_Test_Set" -"gallery": containing 60,294 gallery images from 5,319 test identities (IDs). -"mated_probe": containing 60,423 probe images from 5,319 test IDs, with mated gallery true match images in the "gallery" folder. -"unmated_probe": containing 12,1736 distractor probe face images without mated gallery true match images in the "gallery" folder, i.e. the open-set face identification scenario. -"gallery_img_ID_pairs.mat": the gallery image names and the corresponding face IDs -"mated_probe_img_ID_pairs.mat": the mated probe image names and the corresponding face IDs "Face_Verification_Test_Set": -"verification_images": containing 10,051 images, a subset of the whole test set, randomly sampled to build 5,320 positive and 5,320 negative pairs -"positive_pairs_names.mat": 5320_by_2 cell specifying the image pairs of 5,320 positive pairs -"negative_pairs_names.mat": 5320_by_2 cell specifying the image pairs of 5,320 negative pairs # ======================== Evaluation Instruction ========================== # *** Open-Set Face Identification Evaluation ("Face_Identification_Evaluation") *** 1. Extract features of "gallery" images according to the order defined by "gallery_img_ID_pairs.mat", put them in a matrix called "gallery_feature_map" ([image_number]_by_[feature_dimension]), and save the matrix in a mat file named "gallery.mat" 2. Extract features of "mated_pr
