3D Medical image compression using the quincunx wavelet coupled with SPIHT

, 2020
Medical imaging is a growing field due to the development of digital technologies that produce 3D and even 4D data. The counterpart to the resolution offered by these voluminal images resides in the amount of gigantic data, hence the need for compression.

On a hybrid lossless compression technique for three-dimensional medical images. [PDF]

J Appl Clin Med Phys, 2021
Abstract In the last two decades, incredible progress in various medical imaging modalities and sensing techniques have been made, leading to the proliferation of three‐dimensional (3D) imagery. Byproduct of such great progress is the production of huge volume of medical images and this big data place a burden on automatic image processing methods for ...
