This paper proposes a simple and effective retinal fundus image simulation modeling to enhance contrast adjust the color balance for symmetric information in biomedicine. The aim of study is reliable diagnosis AMD (age-related macular degeneration) screening. method consists few steps. Firstly, local refined with CLAHE (Contrast Limited Adaptive Histogram Equalization) technique by operating CI...

To address the technical shortcomings of conventional histogram equalization (HE), such as over-enhancement and artifacts, we propose a histogram-constrained contrast-tunable HE technique for digital image enhancement. Firstly, input is partitioned into two parts, main constrained histogram, by cumulative probability density threshold; second, redistributed equally in whole grayscale range; fin...

Objective- To evaluate and compare the radiographic efficacy and safety of a non-ionic dimeric and isotonic iodinated contrast medium, iodixanol (320 mgI/ml) and a non-ionic monomer and hypertonic contrast medium, iohexol (300 mgI/ml) in feline cervical myelography. Design- Experimental study Animals- Five adult healthy cats. Procedures- Iodixanol and iohexol were injected into the cerebello...
