The application of deep learning in the field 3D reconstruction has greatly improved quality object reconstruction. For methods that take point cloud as supervision information, previous research mainly focused on network architecture while setting Chamfer Distance (CD) loss default function. However, CD only contains distance information ignoring directional information. In this paper, we intr...

Metric based description and analysis of shapes a fundamental notion in image analysis and processing. Among classical tools, the distance transform (DT) [54, 39] of a binary image I : Zd → {0,1} consists in labeling each point of a digital object E, defined as pixels with value 1 for instance on I, with its shortest distance to the complement of E. In the literature, DT has been widely used as...

A large amount of handwritten historical documents are located in libraries around the world. The desire to access, search, and explore these documents paves the way for a new age of knowledge sharing and promotes collaboration and understanding between human societies. Currently, the indexes for these documents are generated manually, which is very tedious and time consuming. Results produced ...
