About 12-bit image compression
I created a function to normalize a 12-bit image to the range [0,1] and use it as input for network. I wonder whether this is sufficient or if certain parameters in the entropy model (such as scale_table, SCALES_SIN=0.11, SCALES_MAX=256, and SCALES_LEVELS=64) also need to be adjusted to accommodate a larger range."
