Patent ID: 8373752

Claim:
A detection apparatus for detecting an object in real time, being electrically connected to a video capturing apparatus, the video capturing apparatus being configured to capture a video sequence comprising the object, the detection apparatus comprising: a storage unit, being configured to store a noise threshold value for fault-tolerant, search range information as well as a first transformed frame and a second transformed frame generated according to the video sequence, wherein the first transformed frame comprises a first pixel block which at least comprises a first target pixel and a first adjacent pixel adjacent to the first target pixel, and the first target pixel comprises coordinate information with respect to the first transformed frame and the second transformed frame; and a microprocessor, being electrically connected to the storage unit and configured to: retrieve a plurality of first target pixel bits and a plurality of first adjacent pixel bits from the first target pixel and the first adjacent pixel respectively according to the noise threshold value for fault-tolerant; interlace the plurality of first target pixel bits and the plurality of first adjacent pixel bits to generate a first interlaced bit set; and according to the first interlaced bit set and the search range information, retrieve a plurality of first reliable moving blocks from the second transformed frame to determine a position where the object appears in the second transformed frame.
