The correction for the gamma‐ray component in neutron therapy [PDF]

open access: yesMedical Physics, 1980
Neutron beams for therapy always contain some γ ray contamination that varies with depth and with distance from the beam axis. The problem therefore arises how the varying γ ray contribution should be accounted for in dose specification. Not infrequently a “total effective dose” DE is quoted that is equal to the neutron dose plus the γ ray dose divided

Hybrid histogram correction with adaptive gamma and multi-scale retinex for enhanced image processing [PDF]

open access: yesPeerJ Computer Science
In the realm of Applied Artificial Intelligence, conventional image correction algorithms often face challenges when dealing with darker tonalities in images, leading to the loss of details, increased noise, and a lack of contrast and visual impact.

A Flexible Architecture for Precise Gamma Correction

open access: yesIEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2007
We present a flexible hardware architecture for precise gamma correction via piece-wise linear polynomial approximations. Arbitrary gamma values, input bit widths, and output bit widths are supported. The gamma correction curve is segmented via a combination of uniform segments and segments whose sizes vary by powers of two.

Retinex-Based Fast Algorithm for Low-Light Image Enhancement

open access: yesEntropy, 2021
We proposed the Retinex-based fast algorithm (RBFA) to achieve low-light image enhancement in this paper, which can restore information that is covered by low illuminance. The proposed algorithm consists of the following parts.
