Final project of digital video technology

Generate EPI and CALIC compression:

Calic.ipynb : change the directory name, file size(nums,rows,height) It will output a .craw file which contains the 2 bits output of CALIC encoding, and a .dat file contains the arithmetic coding bitstream of CALIC

Decoding : example: calic8d Test1_3_EPI_PAE5_2.dat Test1_3_EPI_PAE5_2_r.raw It will output the restore bitstream of EPI, and to reproduce EPI image and dataset, Calic.ipynb needs to be executed.

Near-lossless Compression:
