A new coding algorithm is proposed for encoding arbitrarily shaped video objects. This algorithm employs an object-based discrete wavelet transform to decompose the video object. The decomposed pyramid is entropy encoded with a modified set partitioning in hierarchical trees (SPIHT) algorithm called partial-SPIHT (P-SPIHT), which only encodes the coefficients belonging to the decomposed video objects. The performance of this algorithm shows that it is a competitive candidate for the standardisation of video object coding
