Abstract. Shadows in satellite and aerospace images are a serious problem in image segmentation and object detection. Therefore, a large number of works and studies is devoted to this topic is devoted, a wide variety of different methods for detecting and eliminating areas of shadows are suggested. In this paper, we consider approaches to the detection of shadows that do not require knowledge of additional information, except the image itself. A comparison of 5 methods of this type, which use

Evaluation of the quality and speed of detection for the considered methods was carried out on a set of test images using 6 criteria. Five criteria for assessing the accuracy of the selected areas are: accuracy, completeness, F-measure, Matthews coefficient, overall accuracy; processing speed was estimated using the time spent on image processing.
