In the paper methods of small-sized objects fi nding in images and videoframes for its selection and control are considered and analyzed. There are different cases of image backgrounds, where small-sized natural and non-natural should be found, are examined. Non-natural objects are distinguied by its straight line borders, and natural ones on the other hand have curved borders. Objects borders on images are recognized by regions with brightness change and well-known differentiating and difference fi lters are implemented for its selection. In general, for solving the task of object selection there are methods of fi ltration and fragmentation. Basing on reviews, recommendations for image processing method choice are given, regarding small-sized objects with characteristics similar to background. Besides, practical recommendations for the methods choice are also presented. It can be implemented for solving tasks of bio-resources evaluation and calculation, of objects selection and localization on images in technical vision systems, etc.
