The proposed method using a combination of image pyramid coder and vector quantization techniques has good performance at compressing confocal volume image data. An experiment was conducted on several kinds of CLSM data using the presented compressor compared to other well-known volume data compressors, such as MPEG. The results showed that the 3D pyramid compressor gave higher subjective and objective image quality and better minutia preservation on reconstructed images at the same compression ratio. </ABSTRACT></RECORD></RECORDS></XML>
