Abstract
In this work we discuss an object-based wavelet image coding system which employs the wavelet packet best basis algorithm to adapt to each object separately. In addition to the increased functionality inherent to any object-based codec, the enhanced rate-distortion performance for images exhibiting objects with different frequency properties is shown.
