nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. to design and implement suchcontrol systems, having information about traffic light colors is essential. there are the wide variety oftraffic lights in terms of light intensity and color. therefore it seems that design and ...

food quality, marketability, soluble solids, size and color of nectarine fruit is affected by the intensity and amount of direct sunlight. usually the outer areas of fruit trees get enough light and take the appropriate color. however, in the middle and lower part of trees, due to low light intensity, fruits have no good color and taste and their marketability were not desirable. to improve the...

Low-visibility conditions for navigation of vehicles are a frequent occurrence. Driving at night, in blizzards, in sand storms, or in fog form an obvious set of challenging conditions. Remote operation of unmanned vehicles through a camera image provides a similar difficulty. Gathering intelligence from satellite imagery can similarly benefit from improved visibility. Advanced image processing ...

Snakes provide high-level information in the form of continuity constraints and minimum energy constraints related to the contour shape and image features. These image features are usually based on intensity edges. However, intensity edges may appear in the scene without a material/color transition to support it. As a consequence, when using intensity edges as image features, the image segmenta...

In a series of experiments color coding, intensity coding, and decluttering were compared in order to assess their potential benefits for accessing information from electronic map displays. Participants viewed electronic battlefield maps containing 5 classes of information discriminable by color or intensity, or, in the decluttering condition, displayed or removed entirely by a key press. Parti...

In a series of experiments, the use of color-coding, intensity coding, and decluttering were compared order to assess their potential benefits for accessing information from electronic map displays. Participants viewed electronic battlefield maps containing five classes of information discriminable by color, intensity, or in the decluttering condition, displayed or removed entirely by a keypres...

The paper presents a novel approach for representing color and intensity of pixel neighborhoods in an image using a co-occurrence matrix. After analyzing the properties of the HSV color space, suitable weight functions have been suggested for estimating relative contribution of color and gray levels of an image pixel. The suggested weight values for a pixel and its neighbor are used to construc...

The design and implementation of an architectural dimming control for multicolor LED-based lighting fixtures is complicated by the need to maintain a consistent color balance under a wide variety of operating conditions. Factors to consider include nonlinear relationships between luminous flux intensity and drive current, junction temperature dependencies, LED manufacturing tolerances and binni...

Objective: Perfusion quantification of tissues is an important goal to evaluate the state of blood supply of an organ. We developed a method to quantify tissue perfusion via color Doppler signal quantification from sonographic videos and applied this to describe renal parenchymal perfusion in healthy kidneys. Method: Color Doppler sonographic videos of renal perfusion from bothkidneys of 87...

Color Constancy is the capability to recognize colors of objects, invariant to the color of the illumination source. This ability is usually endorsed to the Human Visual System, even though the precise details remain hesitant. Visual surveillance is one of the applications of color constancy which aims to improve the reliability of applications that depend on consistent color descriptions. Also...
