The terms"human trafficking,""trafficking in persons,"and"modern slavery"are sometimes used interchangeably to refer to both sex trafficking and forced labor. Human trafficking occurs when a trafficker compels someone to provide labor or services through the use of force, fraud, and/or coercion. The wide range of stakeholders in human trafficking presents major challenges. Direct stakeholders are law enforcement, NGOs and INGOs, businesses, local/planning government authorities, and survivors. Viewed from a very high level, all stakeholders share in a rich network of interactions that produce and consume enormous amounts of information. The problems of making efficient use of such information for the purposes of fighting trafficking while at the same time adhering to community standards of privacy and ethics are formidable. At the same time they help us,...

After an initial wave of special-purpose systolic processors, research has turned to the implementation of programmable systolic machines. These machines are often too large and complicated to be able to support massive parallelism: many of the benefits to be reaped from systolic algorithms are lost. Few of the current architectures provide the simple systolic communication of the early special-purpose processors. The primary contribution of this research is the systolic shared register paradigm. Unlike previous research efforts, the architecture provides a natural means of systolic communication and uses simple processing elements; the architecture can be both easily programmed and easily formed into very large systolic arrays. The main features of the architecture are broadcast instructions, a regular topology, and register sets that are shared between neighbo...

It followed in the same spirit as the first edition with a special focus on digital geometry and mathematical morphology. It was intended as both a short participative course on reproducible research (RR) aspects leading to open discussions with the participants and also on how to actually perform RR. For this second edition, a new call for short papers was proposed to the ICPR authors. The main idea was to give authors of already accepted ICPR papers the possibility to highlight the reproducibility of their work with a companion paper. It was an opportunity to include implementation details, source code descriptions, parameter choice etc. This proceedings volume gathers 14 contributions covering the RR result track (three papers), invited RR contributions (five papers), and t...

These are caused by poor image quality, a wide range of possible camera points of view, pose variations on the part of athletes engaged in playing a sport, deformations of text appearing on sports person’s clothing and uniforms in motion, occlusions caused by other objects, etc. To address these challenges, this paper presents a new method for detecting text on human bodies in sports images. Unlike most existing methods, which attempt to exploit locations of a player’s torso, face, and skin, we propose an end-to-end episodic learning approach that employs inductive learning criteria for detecting clothing regions in an image, which are, in turn, then used for text detection. Our method integrates a Residual Network (ResNet) and Pyramidal Pooling Module (PPM) for generating a spatial attention map. The Progressive Scalable Expansion Algorithm (PSE) is adapted for text detection from these regions. Experimental results on our own dataset as well as several benchmarks (like RBNR and MMM which contain images of runners in marathons, and Re-ID which is a person re-identification dataset) demonstrate that the proposed method outperforms existing methods in terms of precision and F1-score. We also present results for sports images chosen from natural scene text detection datasets such as CTW1500 and MS-COCO to show the proposed method is effective and reliable across a range of inputs.
