FIELD: information technology.
SUBSTANCE: method is offered to compress digital motion pictures or videosignals on the basis of superabundant basic transformation using modified algorithm of balance search. The algorithm of residual energy segmentation is used to receive an original assessment of high energy areas shape and location in the residual image. The algorithm of gradual removal is used to decrease the number of balance assessments during the process of balance search. The algorithm of residual energy segmentation and algorithm of gradual removal increase encoding speed to find a balanced basis from the previously defined dictionary of the superabundant basis. The three parameters of the balanced combination form an image element, which is defined by the dictionary index and the status of the basis selected, as well as scalar product of selected basic combination and the residual signal.
EFFECT: creation of simple, yet effective method and device to perform frame-accurate encoding of residual movement on the basis of superabundant basic transformation for video compressing.
