Abstract
Provided is a method and a system for detecting and segmenting primary video objects with neighborhood reversibility, including: dividing each video frame of a video into super pixel blocks; representing each super pixel block with visual features; constructing and training a deep neural network to predict the initial foreground value for each super pixel block in the spatial domain; constructing a neighborhood reversible matrix and transmitting the initial foreground value, constructing an iterative optimization problem and resolving the final foreground value in the temporal spatial domain; performing pixel level transformation on the final foreground value; optimizing the final foreground value for the pixel using morphological smoothing operations; determining whether the pixel belongs to the primary video objects according to the final foreground value. The present disclosure does not require to set a priori assumption for processing a video, and is especially suitable for big data sets including complicated scenarios.
