Inpainting techniques based on partial differential equations (PDEs) such as diffusion processes are gaining growing importance as a novel family of image compression methods. Nevertheless, the application of inpainting in the field of hyperspectral imagery has been mainly focused on filling in missing information or dead pixels due to sensor failures. [...]

5 p, 1.6 MB Hybrid compression of hyperspectral images based on PCA with pre-encoding discriminant information / Lee, Chulhee (Yŏnse Taehakkyo. School of Electrical and Electronic Engineering) ; Youn, Sungwook (Yŏnse Taehakkyo. School of Electrical and Electronic Engineering) ; Jeong, Taeuk (Yŏnse Taehakkyo. School of Electrical and Electronic Engineering) ; Lee, Eunjae (Yŏnse Taehakkyo. School of Electrical and Electronic Engineering) ; Serra Sagristà, Joan (Universitat Autònoma de Barcelona.

It has been shown that image compression based on principal component analysis (PCA) provides good compression efficiency for hyperspectral images. However, PCA might fail to capture all the discriminant information of hyperspectral images, since features that are important for classification tasks may not be high in signal energy. [...]

5 p, 1.2 MB A fully embedded two-stage coder for hyperspectral near-lossless compression / Beerten, Jente (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Blanes Garcia, Ian (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Serra Sagristà, Joan (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions)
This letter proposes a near-lossless coder for hyperspectral images. The coding technique is fully embedded and minimizes the distortion in the l2 norm initially and in the l∞ norm subsequently. Based on a two-stage near-lossless compression scheme, it includes a lossy and a near-lossless layer. [...]
