- Week 1. Image processing pipeline
- The lectures of the first week cover the following stages of space monitoring information processing: background suppression; detection of isolated groups of bright pixels (areas); estimation of shape parameters of extracted bright areas for classification as stars or tracks; estimation of positions of detected stars; estimation of parameters of detected tracks; astrometric reduction of the image; photometric reduction.
- Week 2. Correlation methods for determining the mutual displacement of images
- Second week discusses a method for determining the mutual displacement of images based on the presence of spatial correlation of the observation background. This method can be used in a situation when the survey is carried out in such a way that the object does not go beyond the field of view of the telescope during the time between two successive frames, and these frames have a significant intersection in absolute angular space.
- Week 3. Spatiotemporal methods of filtering observation background
- Lectures of the third week describe spatio-temporal methods of filtering the observation background. General principles of these methods are considered. The most commonly used methods are described in detail: the simplest nonparametric time filtering algorithm, adaptive autoregression algorithm and algorithm of calculation filter coefficients as an explicit shift function.
- Week 4. Extraction of spatially resolved point objects from digital image
- The fourth week is dedicated to selecting and classifying allowed point objects in a digital image. The general limitations of using the proposed methods are considered. The general structure of the optimal algorithm is described. A method for detecting a single object in a fixed window is proposed. Based on this method, the case of determination the decision-making statistics in the image reference points for a symmetric PSF, conjugated with pixel dimensions, is considered. A suboptimal algorithm for detecting objects at image reference points is proposed.
