Real-time lossless compression

open access: yes, 2000
This thesis covers the selection and design of a lossless coding algorithm for optimal performance of high speed data transfer using a very large-scale integration (VLSI) of the algorithm on a dedicated chip for real time operation.

Perceptually Lossless Image Compression

open access: yes, 2007
This paper presents an algorithm for perceptually lossless image compression. A compressed image is said to be perceptually lossless for a specified viewing distance if the reconstructed image and the original image appear identical to human observers ...

Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.

Lossless, Near-Lossless, and Refinement Coding of Bi-level Images

open access: yes, 1999
We present general and unified algorithms for lossy/lossless coding of bi-level images. The compression is realized by applying arithmetic coding to conditional probabilities.

The MacBrain Resource Center (MBRC) rhesus macaque embryonic brain histology datasets

open access: yesJournal of Anatomy, EarlyView.
We introduce the MacBrain Resource Center (MBRC) Collections of rhesus macaque embryonic brain tissue. Here, we illustrate histo‐ and immunohistology from our dynamically growing Collection 6, which currently contains >10,000 zoomable and downloadable images from n = 14 male and female embryos from early to late in gestation.

Lossless Compression of Multispectral Images Using Prediction and Golomb Rice Coding

open access: yes, 2009
Lossless compression algorithms of multispectral images are typically divided into two stages, a decorrelation stage and a coding stage. This work deals with the design of predictors for the decorrelation stage which are both fast and good.

Autonomous linear lossless systems

open access: yes, 2008
We define a lossless autonomous system as one having a quadratic differential form associated with it called an energy function, which is positive and which is conserved.
