© 2019 Published under licence by IOP Publishing Ltd. A method for identifying antiparticles (antiprotons and antideuterons) of low energies in the sampling imaging electromagnetic calorimeter in the PAMELA experiment is proposed. Tracks of antiparticles before annihilation in detector medium, as well as tracks of secondary particles that were born in the annihilation process, were identified using the Hough transform, the digital image processing method which allows us to search for straight lines on images, which in this case are tracks of particles and antiparticles (searching for the "star" topology).
