Copy-move forgeries are very common image manipulations that are often carried out with malicious intents. Among the techniques devised by the Image Forensic community, those relying on SIFT features are the most effective ones. In this paper we approach the copy-move scenario from the perspective of an attacker whose goal is to remove such features. The attacks conceived so far against SIFT-ba...

intra-industry trade (iit) comprises of instantaneous imports and exports of goods and services which are handled in a same industry. the importance of iit between trading partners refers to those tradable products that provide them with diversity and high technology. to expand its foreign trade relations, iran indeed requires such trade patterns that include diversification of goods and servic...

In the conventional Bag-of-Features (BoF) model for image classification, handcrafted descriptors such as SIFT are used for local patch description. Since SIFT is not flipping invariant, left-right flipping operation on images might harm the classification accuracy. To deal with, some algorithms augmented the training and testing datasets with flipped image copies. These models produce better c...

the relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. this approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. the technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. the ...

This paper describes our contribution to instance search (INS) task for TRECVID 2012. We present four approaches for this task, (i) histograms of SIFT features as feature vectors and Bhatacharya distance for similarity detection (ii) feature vector is combination of SIFT features alone, while for matching we used a basic descriptor matching algorithm (iii) IR based approach using SIFT features ...

if global trade were fair, it is argued, then international aid would be unnecessary and inequalities inherent to the economic system would be justifiable. here, we argue that while global trade is unfair, in part because richer countries set the rules, we believe that additional interventions must go beyond trade regulation and short-term aid to redress inequalities among countries that will p...

In the relevant literature, there has been a lack of discussion to focus particularly on the relationship between entrepreneurship and international trade. It is more restricted when one intends to seek an interaction between international trade and the indexes of the 3A approach of entrepreneurship, including entrepreneurial attitude, activities and aspirations which are collected from Global ...

SIFT is an excellent descriptor to features in medical images. However, the algorithm to achieve SIFT is tedious and takes a long time. To cope with this, we combined image integration and image region partition and proposed a modified SIFT descriptor capable of describing the global energy information of the image. We further proposed a spatial SIFT -oriented non-rigid registration model. Expe...
