Satellite imagery analysis reveals luminance data, not just contrast, effectively estimates visibility parameters. This study presents two new methods for calculating visibility using spatial and frequency domain information from luminance images.
Area of Science:
- Remote Sensing
- Atmospheric Science
- Image Processing
Background:
- Visibility estimation from satellite imagery is crucial for atmospheric studies.
- Traditionally, contrast has been used to assess atmospheric attenuation effects on visibility.
- Spatial and frequency domain analyses offer potential for improved visibility estimation.
Purpose of the Study:
- To examine methods for estimating visibility using satellite imagery.
- To compare luminance and contrast image properties in spatial and frequency domains.
- To demonstrate that luminance data alone is sufficient for calculating visibility parameters.
Main Methods:
- Deriving and comparing properties of luminance and contrast images.
- Analyzing image data in both spatial and frequency domains.
- Developing two novel methods for estimating visibility parameters.
Main Results:
- Luminance image properties contain all necessary information for standard visibility parameter calculation.
- The luminance image provides a more comprehensive dataset than contrast for visibility estimation.
- Both spatial and frequency domain analyses of luminance yield comparable results.
Conclusions:
- Luminance image data is superior to contrast for estimating visibility from satellite imagery.
- The proposed methods offer efficient and accurate ways to calculate visibility parameters.
- This research advances the field of remote sensing for atmospheric monitoring.
