Data from the Hyperspectral Mapper (HyMap), which is acquired with a field of view (FOV) of 61.3 degrees, is disturbed by the bidirectional behavior of the covered surface and its complex geometry. The resulting phenomena, an across-track brightness gradient and spectral differences caused by shifted objects, were described and analyzed in detail. An appropriate correction method for the object...

The widespread application of drones and associated miniaturization imaging sensors has led to an explosion remote sensing applications with very high spatial spectral resolutions. 3-D ultrahigh-resolution digital outcrop models created using oblique imagery from ground-based are now commonly used in the academic industrial sectors, while generation spatially accurate been greatly facilitated b...

background: the aims of this study were to evaluate the employees' subjective assessments of different aspects of lighting condition as well as task area illuminance in manufacturing plants. methods: this field study was conducted between march and may 2013 , in three packing plants (saveh, central iran). data were collected by questionnaire and measurement of the task area illuminance levels. ...

In this paper, the performance of Local Binary Patterns method is evaluated in face recognition with long-wave infrared images. Long-wave infrared images are invariant to illumination conditions, but at the same time are affected by a fixed-pattern noise inherent to this technology. The fixed-pattern noise usually is compensated with a nonuniformity correction method. Here, the robustness of Lo...

In this paper we present an automatic color correction framework based on memory colors. Memory colors for 3 different objects: grass, snow and sky are obtained using psychophysical experiments under different illumination levels and later modeled statistically. While supervised image segmentation method detects memory color objects, a luminance level predictor classifies images as dark, dim or...

Abstract. Camera traps generating a huge number of images help to study and monitor the wildlife. However, camera work at any time day under weather conditions. Therefore, many have low or high illumination, blurring, other defects. This complicates image analysis by both humans computer systems. In this study, we develop an adaptive illumination correction algorithm based on modified Multi-Sca...
