WebJun 24, 2024 · The entropy decode algorithm used in the legacy JPEG codec was serial in nature and was hard to parallelize. In JPEG 2000, the entropy decode stage is applied at a block-based granularity (typical block sizes are 64×64 and 32×32) that makes it possible to offload the entropy decode stage entirely to the GPU. WebEncode message. To encode a message into an image, choose the image you want to use, enter your text and hit the Encode button. Save the last image, it will contain your hidden message.
