About the Book

Al giorno d'oggi, la compressione delle immagini è uno strumento molto importante per risparmiare lo spazio utilizzato dalle immagini per la loro memorizzazione. Negli ultimi giorni, poiché la condivisione e la trasmissione di immagini sui social media è un argomento di tendenza, la compressione delle immagini è diventata più significativa e vitale. La compressione può essere di tipo lossy o lossless. Con la compressione senza perdita, dopo aver ricostruito l'immagine originale utilizzando una tecnica di decompressione, l'immagine finale ottenuta è numericamente uguale all'immagine di ingresso. La tecnica di compressione senza perdita può essere applicata anche ai video, ma viene utilizzata raramente, in quanto la compressione con perdita fornisce rapporti di compressione migliori senza una grande perdita di qualità del video. Esistono molte tecniche di compressione per comprimere le immagini. Uno dei metodi più comuni di compressione delle immagini è la Trasformata discreta del coseno. Nonostante l'utilizzo di diversi metodi avanzati di compressione delle immagini, è possibile utilizzare i passaggi di base utilizzati per la compressione di immagini fisse, con l'inclusione della stima e della compensazione del movimento. In questo progetto, la compressione delle immagini viene ottenuta applicando il metodo della Trasformata discreta del coseno.
