Get matlab code for Lossless Image Compression

I am trying to implement this paper. Here is the link of the paper:

https://www.researchgate.net/profile/Hitoshi_Kiya/publication/281304515_An_E_ffi_cient_Lossless_Compression_Method_Using_Histogram_Packing_for_HDR_Images_in_OpenEXR_Format/links/55e1193d08ae6abe6e8aaab1/An-E-ffi-cient-Lossless-Compression-Method-Using-Histogram-Packing-for-HDR-Images-in-OpenEXR-Format.pdf

Can anyone help me to implement this paper or get some idea for implementing this paper? Thank you.
