Test failing

[jpambrun]

Some images don't produce the same result when decompressed with Matlab.

5-8% of pixels in cameraman and peppers are not reconstructed identically in lossy mode.

1.4% of pixels in 00000.dcm are not reconstructed perfectly in lossless mode (!!). All in the last few rows.

Subsampling 1 and 2 fails completely with the code from pdf.js.

Difference

In both cameraman and peppers cases, the maximum error is 1 suggesting a rounding difference. I will relax the test conditions to accommodate this.
