RT Journal Article T1 Applications of gyrator transform for image processing A1 Rodrigo Martín-Romo, José Augusto A1 Alieva, Tatiana Krasheninnikova A1 Calvo Padilla, María Luisa AB Gyrator transform is a new tool for manipulation of two-dimensional signals such as images or laser beam profiles. Here we demonstrate various applications of the gyrator transform for image processing. Several aspects such as noise reduction, filtering and encryption in the gyrator domains are discussed. These operations can be performed by numerical calculations or by an appropriate optical set up.
