A number of studies have been conducted to enhance the pedestrian detection accuracy of intelligent surveillance systems. However, detecting pedestrians under outdoor conditions is a challenging problem due to the varying lighting, shadows, and occlusions. In recent times, a growing number of studies have been performed on visible light camera-based pedestrian detection systems using a convolut...

This paper describes the fundamentals of the image-resolved luminance and color measurement technique. Its aims and solutions are presented. The determination of image-resolved luminance and color measurements is the state-of-the-art in many applications, e.g. for road or street lighting. In today’s devices, luminance and color measuring cameras are attached to high-quality Charge Coupled Devic...

The detection ability of SO2 cameras has been improved effectively, while the calibration is still main factor that limits their measurement accuracy. This paper presents a nonlinear theory by considering effect light dilution due to path radiance as well dependence plume aerosol on scattering wavelength. new spectral method used retrieve column density and emission rate Etna volcano. Results s...

This paper presents performance test results of true-color night vision cameras. Such cameras are sensitive to the visible to near-infrared (VNIR) portion of the spectrum allowing for the “true-color” of scenes and objects to be displayed and recorded under low-light-level conditions. True-color refers to an approximate reproduction of the subjective colors that would be seen by the human eye i...

Because intelligent surveillance systems have recently undergone rapid growth, research on accurately detecting humans in videos captured at a long distance is growing in importance. The existing research using visible light cameras has mainly focused on methods of human detection for daytime hours when there is outside light, but human detection during nighttime hours when there is no outside ...

In this paper we consider cameras as belonging to one of two types: single aperture (conventional) cameras, and multiple aperture (compound eye) cameras. The eyes of insects are well known examples of the second type. Recently Fraunhofer Institute announced the manufacturing of a compound eye camera, which is very thin and has potential applications unthinkable for the traditional single lens c...

In this paper, we introduce the concept of hyperlines in light fields. When represented by the two-plane parameterization, hyperlines are 2-Degree-of-Freedom (2-DOF) linear entities in the 4-D light field. The light field can be thought of as a dual space of the world space. In this dual space, cameras appear as hyperlines with heterogeneous colors which we call camera hyperlines (CHL), while s...
