\u00c8 stato pubblicato su GitHub un progetto JPEG Quant Smooth<\/a><\/noindex>, progettato per rimuovere artefatti di compressione dalle immagini JPEG. Questo viene raggiunto ripristinando la precisione dei coefficienti della trasformata coseno discreta. Tuttavia, nei limiti consentiti dalla tabella di quantizzazione, ci\u00f2 non consente all'algoritmo di rifiltrare l'immagine. Il codice \u00e8 scritto in C con ottimizzazioni per SSE2, AVX2 e ARM Neon. Inoltre disponibile<\/a><\/noindex> c'\u00e8 una versione WebAssembly, che consente di elaborare le immagini nel browser (ma pi\u00f9 lentamente rispetto alla versione nativa a causa della mancanza di ottimizzazioni SIMD e multi-threading).<\/p>\n

Secondo le affermazioni dell'autore, il suo algoritmo funziona significativamente pi\u00f9 velocemente rispetto a un progetto simile jpeg2png<\/a><\/noindex> e produce immagini pi\u00f9 nitide. Tuttavia, l'autore ammette che jpeg2png potrebbe funzionare meglio in casi complessi. Un altro progetto, knusperli<\/a><\/noindex>, pubblicato sotto l'account Google \u2014 che dovrebbe anche rimuovere gli artefatti JPEG, secondo l'autore \u00abnon serve a nulla\u00bb e \u00ab\u00e8 difficile notare miglioramenti dal suo lavoro\u00bb.<\/p>\n
