Abstract EN
An effective scheme for coding of arbitrarily shaped color visual objects is presented.
Based on Set Partitioning In Hierarchical Trees (SPIHT) algorithm, the proposed algorithm employs the Shape-Adaptive Discrete Cosine Transform (SA-DCT) in the place of the Shape-Adaptive Discrete Wavelet Transform (SA-DWT) to code texture coefficients by using mask pixels in order to create an embedded code that allows for fine-grained rate-distortion scalability.
The result of the proposed procedure is a multiresolution, progressive reconstruction of the binary shape mask as well as the texture.
This algorithm is compared with wavelet-based embedded coding of the object texture.
Objective and subjective simulation results show that the proposed scheme has excellent rate-distortion performance.
