Provided are a staircase code decoding method and a staircase code decoding apparatus. The method includes: step, obtaining the length L of a sliding window, and continuously obtaining, starting from a P-th subcode block, L subcode blocks as first to-be-decoded subcode blocks in the sliding window; step, dividing the first to-be-decoded subcode blocks into a plurality of first to-be-decoded groups, respectively decoding the plurality of to-be-decoded groups to be decoded, and updating the plurality of first to-be-decoded groups according to a decoding result to obtain first updated subcode blocks; step, sliding the sliding window forwards by a length of N subcode blocks; step, dividing second to-be-decoded subcode blocks into a plurality of second to-be-decoded groups, decoding the plurality of second to-be-decoded groups, obtaining second updated subcode blocks, and outputting first M subcode blocks among the second updated subcode blocks; and step, sliding the sliding window backwards by S.

Embodiments described herein provide various examples of a real-time face-detection, face-tracking, and face-pose-selection subsystem within an embedded video system. In one aspect, a process for performing real-time face-pose-estimation and best-pose selection for a detected person captured in a video is disclosed. This process includes the steps of: receiving a video image among a sequence of video frames of a video; performing a face detection operation on the video image to detect a set of faces in the video image; detecting a new person appears in the video based on the set of detected faces; tracking the new person through subsequent video images in the video by detecting a sequence of face images of the new person in the subsequent video images; and for each of the subsequent video images which contains a detected face of the new person being tracked: estimating a pose associated with the detected face and updating a best pose for the new person based on the estimated pose. Upon detecting that the new person has disappeared from the video, the process then transmits a detected face of the new person corresponding to the current best pose to a server, wherein transmitting the detected face having the best pose among the sequence of detected face images reduces network bandwidth and improves storage efficiency.
