人脸识别是一个开集问题,人脸验证verification是一个闭集问题。训练样本可能是甲乙,测试样本可能是丙丁。通过训练样本来学习PCA的投影向量。gallery相当于新的训练集,在Probe上测试。在The CAS-PEAL large-scale Chinese face database and baseline evaluations (TSMCA 2008)P155也有Training set、 gallery set、Probe set定义
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
