CDeC-Net: Composite Deformable Cascade Network for Table Detection in Document Images

Localizing page elements/objects such as tables, figures, equations, etc. is the primary step in extracting information from document images. We propose a novel endto-end trainable deep network, (epee-Net) for detecting tables present in the documents. The proposed network consists of a multistage extension of Mask R-CNN with a dual backbone having deformable convolution for detecting tables varying in scale with high detection accuracy at higher iou threshold. We empirically evaluate epee-Net on the publicly available benchmark datasets with extensive experiments. Our solution has three important properties: (i) a single trained model CDeC-NeT double dagger that performs well across all the popular benchmark datasets; (ii) we report excellent performances across multiple, including higher, thresholds of iou; (iii) by following the same protocol of the recent papers for each of the benchmarks, we consistently demonstrate the superior quantitative performance. Our code and models are publicly available at https://githuh.com/mdv3101/CDeCNet for enabling reproducibility of the results.
