ABSTRACT
The main goal of the immediate monitoring based on the remote sensing data is detection of changes in different natural and anthropogenic processes and objects. Monitoring bases on remote sensing data is irreplaceable in observation of dangerous natural phenomena and catastrophes, investigating territories, which are difficult to access, determination of unauthorized construction works, etc. Immediacy and quality of monitoring in the conditions of town infrastructure directly depends on spatial resolution of the satellite data, as well as on the presence of additional interferences, such as shadows of tall buildings and others. However, to extract shadows, the automated detection of shadows from images must be accurate. In this paper, an improved algorithm for detecting and compensating shadows with the use of the infrared channel is proposed. The results after the evaluation on the satellite images exhibit that the recovered shadow regions are consistent with their neighboring nonshadow region.
