Multiresolution Histogram Analysis for Color Reduction [PDF]
, 2010 A new technique for color reduction is presented, based on the analysis of the histograms of an image at different resolutions. Given an input image, lower resolution images are generated by using a scaling down interpolation method. Then, peaks and pits that are present in the histograms at all resolutions and dominate in the histogram of the input ...

Enhanced CEST MRI Using the Residual of Inversed Z-Spectra for Ischemia Detection
IEEE Access, 2020 Chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI) had shown potential in sensing pH changes that occurs early in ischemic stroke. However, detection of mild acidosis is still challenging. To enhance CEST detection for ischemia,

Improved program for the analysis of DNA histograms [PDF]
Cytometry, 1987 AbstractWe describe a computer program which will rapidly analyze a set of DNA histograms without further operator intervention after the initial input. The algorithm used was modified from that of Watson et al. (Cytometry 8:1–8, 1987). The program, coded in Pascal, has been implemented on two different systems.

HBOS-CNV: A New Approach to Detect Copy Number Variations From Next-Generation Sequencing Data
Frontiers in Genetics, 2021 Copy number variation (CNV) is a genomic mutation that plays an important role in tumor evolution and tumor genesis. Accurate detection of CNVs from next-generation sequencing (NGS) data is still a challenging task due to artifacts such as uneven mapped ...
