It provides the binary GT mask of the tampered image and the corresponding tampered regions. In the reference arm, a mirror reflects the light, 2. CASIA v2 image dataset [26] is used to evaluate the proposed method, which is widely used to detect image forgery and is publicly available. HiFiMask (CASIA-SURF HiFiMask) Introduced by Liu et al. models 2. First, we only choose part (576 pixel length of the images in this paper) of the original text images for training each time, because shorter training images can speed up the training process several times for each mini-batch The CASIA-B gait database [6] is the largest publicly available multi-view gait dataset, which consists of 124 subjects under 11 view angles (i. In the CASIA Gait Database there are three datasets: Dataset A, Dataset B (multiview dataset) and Dataset C (infrared dataset). Fake samples are shown in Fig. In recent years, heterogeneous face biometrics has attracted more attentions in the face recognition community. A large scale dataset, called CASIA-WebFace, is built, which contains about 10,000 subjects and 500,000 images. c72e1dc 5 months ago. (i. How to get CASIA-E dataset? #2.

The dataset contains 504 samples from 14 subjects, consisting of 230 LF images of bona fide iris and 274 LF images of spoofing iris. Each person has 12 image sequences and 4 sequences for each of the three directions. This is technically a single impression dataset, but since every finger is present twice as rolled and flat impression, the dataset can be considered a pairset. CASIA-SURF dataset to verfiy its significance and general-ization capability. O’Reilly members experience books, live events, courses curated by job role, and more from O’Reilly and nearly 200 top publishers. generated the corresponding Groundtruth in a 2019 paper contributed Center for Advanced Studies in Adaptive Systems (CASAS) School of Electrical Engineering and Computer Science EME 121 Spokane Street Box 642752 Washington State University The UBIRIS. 2, and the handwritten texts are divided into three It is recommended to add the samples of DB1. 0, 1368 are available for training and 343 for testing. 3). Three variations, namely view angle, clothing and carrying condition changes, are separately considered. To verify the effectiveness of the model in the multi-modal dataset, the training and testing were conducted on the multi-modal CASIA-SURF dataset. We agree with [13,19] that among all of the publicly available datasets, CASIA 2 is the latest state-of-the-art splicing and copy–move attack dataset having a large number of color image samples in varying pixel dimensions which portray natural and realistic image forgery and thus, a robust forgery detection method should have PGPS9K is composed of 9,022 geometry problems paired with non-duplicate 4,000 geometry diagrams, where 2,891 problems paired with 1,738 diagrams are selected from Geometry3K dataset, the rest of problems are collected from five popular textbooks across grades 6-12 on mathematics curriculum websites .
