Tightening financial regulation squeezes banking activities into the shadow banking sector, which may hurt financial stability and production (Plantin, 2014). Unlike Plantin’s work, we investigate regulations that reduce banks’ leverage and dampen financial amplification effects. Moreover, our paper studies the trade-off between economic growth and financial stability in light of shadow banking...

This paper presents a model of shadow banking in which the shadow and the traditional banking systems share a symbiotic relationship. The analysis shows that competition with an opaque and fragile shadow bank can bene…t the traditional bank, especially when the traditional bank faces liquidity risk stemming from collective actions by investors, such as runs. The opacity and fragility of the sha...

This paper presents a method that combines shadow detection and a 3D box model including shadow simulation, for estimation of size and position of vehicles. We define a similarity measure between a simulated image of a 3D box, including the box shadow, and a captured image that is classified into background/foreground/shadow. The similarity measure is used in an optimization procedure to find t...

Shadows are physical phenomena observed in most natural scenes. They can cause many problems in computer vision performance. The paper addresses the problem of shadow detection and removal from solo image of natural scenes. Our method is based on Retinex theory which is an image enhancement and illumination compensation model of the lightness and color perception of human vision. The approach p...

We propose a novel shadow texture generation method with linear processing time using a shadow depth buffer (SZ-Buffer). We also present a method that achieves further speedup using temporal coherence. If the transition between dynamic and static state is not frequent, depth values of static objects does not vary significantly. So we can reuse the depth value for static objects and render only ...

We present a method, based on Haines' shadow caches, for accelerating shadow ray calculations for Tay tracing processes which use spatial subdivision and surface tessellation. Trees of shadow voxel caches, containing references to both objects and voxels, are used to quickly determine whether or not a surface lies in shadow. This method does not require an additional preprocessing stage before ...

In recent years, various shadow detection methods from a single image have been proposed and used in vision systems; however, most of them are not appropriate for the robotic applications due to the expensive time complexity. This paper introduces a fast shadow detection method using a deep learning framework, with a time cost that is appropriate for robotic applications. In our solution, we fi...

We propose a new touch screen interaction named as Touch Shadow, which is based on the contact area and the resultant shape of the fingertip when it touches the touch surface. The results of our feasibility evaluation established three degrees of freedom for the Touch Shadow interaction based on three fundamental parameters, the touch surface area, displacement of the touch centroid and directi...

Intelligent video surveillance systems detect pre-configured surveillance events through background modeling, foreground and object extraction, object tracking, and event detection. Shadow regions inside video frames sometimes appear as foreground objects, interfere with ensuing processes, and finally degrade the event detection performance of the systems. Conventional studies have mostly used ...
