In [3], this property is stated to be important for gray-level images by means of the contourlet transform and its pyramidal directional filter bank.(More)
This paper investigates a complementary compression concept to the JPEG 2000 standard for improving the compression efficiency of medical images , in terms of compression ratio and image quality, by introducing a denoising process before the application of the JPEG2000 compression. The case of dental radiography is assessed, where the JPEG 2000 compression(More)
