English Abstract

Atmosphere modifies the radiance reflected from the ground and contributes in an additive path radiance term.

It is necessary then to correct the atmospheric effect to retrieve the surface reflectance.

Atmospherically corrected surface reflected images improve the accuracy of surface classification and Earth's reflected data.

The problem to estimate surface reflectance is the assessment of the path radiance.

In this research, computation of atmospheric characteristics is based on the dark object theory; atmospheric parameters are observed in regions were the absorption is maximal.

Histogram satellite image has been used to estimate path radiance; i.e.

histogram peak value is adopted.

Histogram mean and standard deviation are also used for the path radiance estimation.

For the image bands in the visible spectrum, water areas involve some non-zero DN values.

These non-zero DN values are adopted to represent the path radiance.

The most probable "histogrampeak" is introduced to overcome the problem of non-zero existed values.

As a fidelity test, regions that have been considered to represent the path radiance are classified and isolated from other image regions.

The degree of correlation between isolated image regions has been considered to satisfy the implemented method for path radiance estimation.

Eigen values and covariance matrix of the principal components have been used for this qualification test
