Quality evaluation of compressed optical and SAR images: JPEG vs. wavelets
Mihai P. Datcu, Gottfried Schwarz, Kersten Schmidt, Christoph Reck · 2002
Presents a comparison of compression algorithms using the discrete cosine transform-DCT (JPEG) and discrete wavelet transform-DWT applied to remotely sensed images. The statistical behaviors of the DCT and DWT are addressed and the implications for the performance of the image compression algorithms are compared for optical and SAR images. These SAR images were despeckled during compression. Qualitative and quantitative results are presented.
