In this paper, we present a user-friendly and practical method for seamless integration of computergenerated images (CG) with real photographs and video. In general, such seamless integration is extremely difficult and requires recovery of real-world information to simulate the same environment for both CG and real objects. This real-world information includes camera positions and parameters, s...

Embryonic stage of development, in conditions of intensive broiler production, is a period in which the dynamics of postnatal development and the productive performance can be affected significantly. Green monochromatic light and thermal conditioning are the most commonly used treatments that have given satisfactory results in postnatal development. The aim of this study was to examine the effe...

The implementation of codesign applications generally requiresthe use of heterogeneous resources (e.g., processor cores, hardware accelerators) in one system. Inteifacing hardware and software components together and providing communications between them are particularly error proned and time consuming tasks. Hence, on the basisof a generic architecturewe propose an extended communicationsynthe...

Estimating the contribution of a blurred photon plane involves the computation of an integral along the interval of overlap between the camera segment and the photon plane. In order to reduce variance introduced by this estimation, we apply control variates [Glasserman 2003] in our implementation of the photon plane estimator for homogeneous media. The concept of control variates is simple. Say...

Face of an individual is a biometric trait that can be used in computer-based automatic security system for identification or authentication of that individual. While recognizing a face through a machine, the main challenge is to accurately match the input human face with the face image of the same person already stored in the face-database of the system. Not only the computer scientists, but t...

Despite the obvious importance of thermal comfort in the design of indoor environment, it has not been effectively integrated with design decision support tools. The reasons can be attributed in part to an absence of modular and flexible software architecture that facilitates dynamic data transfer between energy performance, lighting simulation, and thermal comfort modules. Research has shown t...

. light is an environmental factor, which has profound influences on broilers performance and frequently overlooked management practices. this study was conducted to compare the effects of different lighting programs on growth, carcass parts and economical performance using 320 one day–old broilers (arian 386) in completely randomized design with 4 treatments and 8 replicates per each treatment...

BACKGROUND Traditionally, epidemiologists have considered electrification to be a positive factor. In fact, electrification and plumbing are typical initiatives that represent the integration of an isolated population into modern society, ensuring the control of pathogens and promoting public health. Nonetheless, electrification is always accompanied by night lighting that attracts insect vecto...

Interactively simulating visual appearance of natural objects under natural illumination is a fundamental problem in computer graphics. 3D computer games, geometry modeling, training and simulation, electronic commerce, visualization, lighting design, digital libraries, geographical information systems, economic and medical image processing are typical candidate applications. Recent advances in...
