Naturally if you have the original raw data to compare. You almost never do, that’s why you compress. For example, some compressors built into camera electronics spit out compressed directly. But a perceptual lossless compressor might not remove ANY information. It might be effectively lossless it’s not guaranteed to be lossy. For example, an audio recorder that records a subset of the frequencies detectable by the human ear or a camera that only records subtle shades of red might produce lossless. Granted in most applications it’s lossy but conceptually you don’t know unless you have the original defeating the purpose of compressed data transmission. ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/T252d8aea50d6d8f9-M6f62bb90546303649cb85e39 Delivery options: https://agi.topicbox.com/groups/agi/subscription
