Single Image Dehazing Using Color Ellipsoid Prior.
Summary
This study introduces a novel single-image dehazing method using color ellipsoids for robust transmission value calculation. The approach effectively enhances image contrast and prevents artifacts, enabling real-time applications.
Area of Science:
- Computer Vision
- Image Processing
Background:
- Hazy images degrade visual quality and hinder subsequent image analysis tasks.
- Existing single-image dehazing methods often struggle with artifacts or computational complexity.
Purpose of the Study:
- To propose a novel and efficient single-image dehazing method.
- To enhance image contrast while preventing over-saturation and artifacts.
Main Methods:
- Constructs color ellipsoids statistically fitted to haze pixel clusters in RGB space.
- Calculates transmission values using color ellipsoid geometry and embedded fuzzy segmentation.
- Integrates refinement process within transmission calculation to avoid complex post-processing.
Main Results:
- Achieves statistically robust transmission values by averaging haze pixel values.
- Effectively maximizes contrast of dehazed pixels without over-saturation.
- Demonstrates superior performance compared to prevailing methods across various haze and noise levels, without visible artifacts.
Conclusions:
- The proposed method offers an effective and efficient solution for single-image dehazing.
- Its low complexity facilitates real-time applications.
- The integrated approach successfully handles transmission calculation and artifact reduction simultaneously.

01:28Geoid and Ellipsoid
720
The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:14Changes in Skin Color: Clinical Perspectives
3.7K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

In structural engineering, the analysis of beams subjected to varying loads is a critical aspect of understanding the behavior and performance of these structural elements. A common scenario involves a beam subjected to a combination of different load distributions.
Consider a beam of length L subjected to a varying load, which is a combination of parabolic and trapezoidal load distribution along the x-axis. In this case, it is essential to determine the resultant loads, their locations, and...
