Kaggle is the world’s largest data science community with powerful tools and resources to help you achieve your data science goals. The images of this database were collected in four recording sessions: 2007 spring, 2009 summer, 2009 fall and 2010 summer, in which the first session is identical to the CASIA HFB database. [34], Hu et al Jul 1, 2013 · The CASIA 2. 2). The Columbia Gray [ 12 ] dataset contains image blocks of gray color that are extracted from the CalPhotos dataset [ 17 ]; spliced images in this dataset are constructed using a basic cut-paste operation without applying any post 一些数据集处理相关的 API View on GitHub CASIA 手写汉字简介 CASIA-HWDB 和 CASIA-OLHWDB 数据库简称为 CASIA。 由中科院自动化研究所在 2007-2010 年间收集； 包含 1 020 人书写的脱机（联机）手写中文单字样本和手写文本； 用 Anoto 笔在点阵纸上书写后扫描、分割得到。 Jan 2, 2024 · After optimizing the features of the noise-added and tampered images taken from the CASIA dataset, the classification of these images was performed by a deep learning architecture containing GRU As a result of the experiments, 80. The ground truth images are taken from the CASIA image tampering detection evaluation (ITDE) v1. ELA is used to identify tampering by analysing compression level inconsistencies. CasiaV1. Image forensics has now raised the anxiety of justice as increasing cases of abusing tampered images in newspapers and court for evidence are reported recently. Leveraging the CASIA 2. 0 is a dataset for Image Tampering Detection Evaluation, which was published by Jing Dong et al in 2013. al, CASIA image tampering detection evaluation database, ChinaSIP2013), which contains images from eight . 25% accuracy was May 17, 2022 · The modified CASIA dataset is created for research topics like: perceptual image hash, image tampering detection, user-device physical unclonable function and so on. 0做 Apr 5, 2025 · CASIA V2 是用于伪造分类的数据集。 The Beijing Traffic Dataset collects traffic speeds at 5-minute granularity for 3126 roadway segments in Beijing A custom Convolutional Neural Network (CNN) for feature extraction and forgery detection. 5% accuracy was obtained with the proposed architecture on Gaussian and salt & pepper noise, and 96. Source: Copy-Move Forgery Classification via Unsupervised Domain Adaptation CASIA 2. 1 The self-developed iris camera used for collection of CASIA-Iris-Interval Fig. 2 CASIA-Iris-Lamp 1. It contains 4795 images, 1701 authentic and 3274 forged. 0 includes 921 tampered images and their corresponding original images, with a fixed resolution of 384x256, and the tampering method is limited to Splicing. Since the CASIA_v2 dataset is more comprehensive compared to the CASIA_v1 dataset, we obtained 99. 10 Likewise, for CASIA 2. Dong, et. 0做迁移，V1. generated the corresponding Groundtruth in a 2019 paper contributed it to Github. Dataset B* (CASIA-B*) is a re-segmented version of CASIA-B processed by Liang et al. 3% accuracy for the fine-tuned model using transfer learning and 81% accuracy without transfer learning with the CASIA_v2 dataset. 0 database offers pairs of mugshot images and their correspondent NIR photos. Sep 28, 2021 · The datasets are Columbia Gray , Columbia Color , CASIA 1. 0 and 2. 0 includes 5123 tampered images and their corresponding original images, with resolutions ranging from 320x240 to 800x600, and in addition to Splicing, blurring is also used. 0篡改图片应该是9k张左右，由于两个版本数据集样本数量差距还蛮大的，很多论文在模型评测时使用V2. See full list on github. 0 dataset, Hosney et al. 0+V2. 2 Example iris images in CASIA-Iris-Interval. 0 , DSO-1 , DSI-1 , Wild Web , and AbhAS . ELA + VGG16 Model: Mar 10, 2022 · We evaluated the performance of our technique with the CASIA_v1 and CASIA_v2 datasets. 0 dataset, a widely used collection for image forensics research. It is trained on CASIA 2. The extra import of CASIA-B* owes to the background subtraction algorithm that CASIA-B uses for generating the silhouette data tends to produce much noise and is outdated for real-world applications nowadays. Jul 13, 2020 · Because of this novel design, our iris camera can capture very clear iris images (see Fig. The graphical illustration of the model is demonstrated in Fig. CASIA NIR-VIS 2. 0 database (J. 44%. Contribute to namtpham/casia2groundtruth development by creating an account on GitHub. 2. 0. 0 Image Tampering Detection Dataset, which consists of authentic (Au) and tampered (Tp) images, along with metadata and annotations provided in the CASIA 2 Ground truth However, the proposed method obtained an accuracy rate of 99. 0 dataset comprises 12,613 images with 900 × 600 resolution in BMP, TIFF, or JPG format, 7491 real images, and 5122 fake images [46]. With the goal of verifying image content authenticity, passive-blind image tampering detection is called for. However, this dataset is lack of the groundtruth images comparing to other Image Tampering Detection Datasets. Recently, we collect a natural color image Apr 9, 2025 · CASIA V1. 0/2. qhjwd osos irbx oxabk jnxnnu noszrksz efbn bwowq fwj jlwvv kjvfkkh iedzd hop coaup frieux
