Shadow banking is a term that came out of the financial crisis of 2007-2009. There is a belief that shadow banking was one of the crisis reasons. Because the excessive expansion of shadow banking endangers the financial stability of countries, this paper examines the impact of shadow banking on financial stability using data from 14 countries of the G20 during 2002-2018. We divided countries in...
The reconstruction of the information contaminated by cloud and cloud shadow is an important step in pre-processing of high-resolution satellite images. The cloud and cloud shadow automatic segmentation could be the first step in the process of reconstructing the information contaminated by cloud and cloud shadow. This stage is a remarkable challenge due to the relatively inefficient performanc...
سایه انداز گیاه (cc) و شاخص سطح برگ (lai) نمایه هایی جهت برآورد مقادیر تابش دریافتی توسط گیاه است که بر شبیه سازی بیولوژیک گیاه تأثیر زیادی دارد. اخیراُ در برخی از مدل های گیاهی، برای مشخص کردن وضعیت رشد گیاهی در مزرعه، استفاده از cc جایگزین lai گردیده است. در این تحقیق ماده ی خشک گیاهی، عملکرد دانه و شاخص هایcc و lai طی دو سال زراعی 1389-1390 و 1390- 1391 در مزرعه پژوهشی در دانشکده کشاورزی دانش...
In this paper, we present a new method for creating shadow texture atlas with which we can represent the self-shadow. Shadow texture atlas is a texture atlas with shadow information in each texel. Shadow texture is effective to represent high-quality shadow using the graphics hardware because it stores shadow information as color unlike shadow map which stores depth. However, it cannot represen...
Natural resource rent affects countries’ economies through various channels. Revenues from the natural resources sales are expected to boost countries' economic growth, but the economic experience of recent decades reveals the numerous economic problems in these countries, the most important of which may be the increase in the shadow economy size. Moreover, the institutions specify the signific...

Shadow detection in real scene images is always a challenging but yet interesting area. Most shadow detection and segmentation methods are based on image analysis. This paper aimed to give a comprehensive and critical study of current shadow detection methods. Various approaches have been discussed related to shadow detection in images. The principles of these methods rely on intensity differen...
Varying illuminations, especially the side lighting effects in face images, is one of the major obstacles in face recognition systems. Various methods have been presented for face recognition under different lighting conditions witch require previous knowledge about Light source and shadow area. In this paper, a novel approach based on H-minima transform to image segmentation and illumination n...
Natural gas plays a key role in Iran’s economy and using its shadow price in allocating it to different sectors can lead to optimal use of this resource. This study uses a non-linear input-output model to estimate the shadow price of natural gas in different economic sectors in Iran. The study uses values of the input-output table constructed by the Statistics Center of Iran for the year 2011. ...
Image may contain shadow, which can lead to serious problem for full exploitation of image. This paper proposes A Novel Processing Chain to solve this problem. The main aim of this chain process is not only detect shadow region form image but also remove shadow region and reconstruct shadow less image. In this chain process, initially we classified shadow vs. nonshadow region by using binary cl...
