Lossless Hyperspectral Image Compression Using Context-Based Conditional Averages
In this paper, we propose a compression algorithm focused on the peculiarities of hyperspectral images. The spectral redundancy in hyperspectral images is exploited by using a con...

Compression color space estimation of JPEG images using lattice basis reduction
Given a color image that was quantized in some hidden color space (termed compression color space) during previous JPEG compression, we aim to estimate this unknown compression co...

Chromatic / Achromatic Separation in Noisy Document Images
—This paper presents a new method to split an image into chromatic and achromatic zones. The proposed algorithm is dedicated to document images. It is robust to the color noise i...
