Efficient implementation of mpeg-4 object-based video encoder
This paper presents the efficient sqftivarebased implementation of MPEG-4 video encoder fbr coding the arhitraril,v shaped video objects on a single-prucessor PC. This video encoder conforms to the Core Prq/ile@LeveI 2 qf MEPG-4 vi.stial. The novel coding tools siipporting.for objectbased coding ivill miich increase the cumpzitalional barden in comparison with conventional flame-based video coding system. In order to process the.se ertra camputafional tasks ef’ecriveli~, de.sign techniqnes on algurithm have to De addressed. The fast algorithms iised for shape and texfnre coding are disciissed in detail in this paper. To enhance the compiitafiun speed. we also harness Intel’s MMX (MirltiMedia eXtenvion) technology to implement some algorithms in an SIMD (Single lnstniction Multiple Data) stream operation ype within the same prvce.ssor’. Index Terms MPEC-4, shape coding, video encoder.
