Abstract. The color of an image may be affected by many factors such as illumination, complex and multispectral reflections, and even the acquisition device. Especially in outdoor scenes, these conditions cannot be ...

The colors of fruits and flowers are traditionally viewed as an adaptation to increase the detectability of plant organs to animal vectors. The detectability of visual signals increases with increasing contrasts between ...

We measured at the fovea the chromatic contrast threshold for stimuli modulated along different chromatic directions in the isoluminant plane of MBDKL colour space, considering the two cardinal axes (L+M) and S/(L+M) and ...

Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin. These cells receive afferent inputs from rods and cones, which provide inputs to the postreceptoral visual pathways. It is ...

We have adapted an actin-mosin motility assay to examine the interactions in vitro between actin cables isolated from the giant internodal cells of the freshwater alga, Nitella, and pigment granules extracted from red ...

CHRA is a hydrophobic protein that expels chromate dependently membrane potential. CHRA bacterial homologous are grouped within the CHR chromate transporter superfamily. They are classified according to their size in ...

The present work is a research to know the parameters of the intervention proposal for the Narváez Ordóñez family’s house, located in Cuenca city, which is looking for a change of use to a Dental Center. For this purpose, ...

This work presents a methodology to estimate the correlated color temperature and the luminous flux of light sources composed of one or more white LEDs using only data from the manufacturer's specification sheet. The ...
