Is there any function to know about the bit depth? Actually I want to calculate the compression ratio. For this I have calculated no of bits in the original image. Now y (as in above code ) is my reconstructed image. For this I want to know the no of bits. I am using no_of_bits=Height * width* bitdepth/ 8 bytes

If there is any other way to calculate the compression rat
