Basic Compression Tools


In this chapter, we first briefly introduce basic compression tools. Generally, compression techniques are classified into two categories: lossy and lossless techniques. A typical image compression scheme incorporates three fundamentals steps: transformation, quantization, and entropy coding. Indeed, the JPEG 2000 image coding framework is commonly used for holographic compression because of its modular and extendable architecture. These three steps will be discussed in more detail hereafter. We shall focus especially on wavelet-based schemes, as they offer appealing features for holographic data. Furthermore, as a special case of wavelet-based schemes, we shall also introduce JPEG 2000, which has been ...
