Evaluation of on-board integer wavelet transform based spectral decorrelation schemes for lossless compression of hyperspectral images

Töreyin, Behçet Uğur; Yılmaz, Ozan; Mert, Yakup Murat (2014)

Integer-coefficient Discrete Wavelet Transformation (DWT) filters widely used in the literature are implemented and investigated as spectral decorrelator for on-board lossless hyperspectral image compression. As ...
Hyperspectral image compression using an online learning method

Ülkü, İrem; Töreyin, B. Uğur (2015)

A hyperspectral image compression method is proposed using an online dictionary learning approach. The online learning mechanism is aimed at utilizing least number of dictionary elements for each hyperspectral image under ...
Lossless Hyperspectral Image Compression Using Wavelet Transform Based Spectral Decorrelation

Töreyin, Behçet Uğur; Yılmaz, Ozan; Mert, Yakup Murat; Türk, Fethi (IEEE, 2015)

Integer-coefficient Discrete Wavelet Transformation (DWT) filters widely used in the literature are implemented and investigated as spectral decorrelator. As the performance of spectral decorrelation step has direct impact ...
Lossy Compression of Hyperspectral Images Using Online Learning Based Sparse Coding

Ülkü, İrem; Töreyin, Behçet Uğur (IEEE, 2014)

A lossy hyperspectral image compression method is proposed using online learning based sparse coding. The least number of coefficients are obtained to represent hyperspectral images by applying the sparse coding algorithm ...
Sparse coding of hyperspectral imagery using online learning

Ülkü, İrem; Töreyin, Behçet Uğur (Springer, 2015-05)

Sparse coding ensures to express the data in terms of a few nonzero dictionary elements. Since the data size is large for hyperspectral imagery, it is reasonable to use sparse coding for compression of hyperspectral images. ...
