Initial registers pages classification dataset overview This dataset is prepared to train classification models for French 19th-century land registry pages. It deals only with initial registers pages (états de sections in French). Images have been provided by the Val de Marne Archive and they can be associated with two former French departements : the Seine and the Seine-et-Oise (departements that were rounded Paris before 1968). There are three main layouts in these registers which are presents here. The dataset counts 1046 simple pages (1016 in version 1) and has been split into training, validation, and test sets with stratification based on the type of page. It is structured according to YOLO Classification format. The metadata_v2.json file gives more information on the pages of the dataset (version 2). The additionnal_pages.json gives the information related to the pages added to version 2. 📁 Usage This dataset is intended for training a YOLO-v11 classification model. Differences with version 1 Version 2 is an augmented version of the dataset (+30 pages). The train subset is exactly the same as in version 1. The less represented classes (ets_couv and ets_resume) in the val and test subsets have been manually augmented to strengthen the evaluation. 📊 Dataset Splits Split Count Diff. with V1 Train 745 = Val 137 +14 Test 164 +16 🏙️ Grouped by municipality Communes are distinct across splits (useful to test geographic generalization), as land registry were produced for each municipality under the supervision of each departement.
