WebEfficient Belief Propagation Polar Decoder With Loop Simplification Based Factor Graphs Abstract: The performance of belief propagation list (BPL) decoding of polar codes is related to the selection of L factor graphs (FGs), which have the least number of girths. However, the straightforward search of such FGs is of high complexity. WebIn the case of Belief Propagation (BP), a key reason for its slow performance is that the algorithm complexity is proportional to both the number of pixels in the image, and the number of labels in the underlying image segmentation, which is typically high. If we could limit the number of labels, its speed performance should improve greatly. WebBelief propagation (BP) has become widely used for low-level vision problems and various inference techniques have been proposed for loopy graphs. These … nys mental health facilities
