A novel framework for MR image segmentation and quantification by using MedGA.

TL;DR: A novel evolutionary framework for image enhancement, automatic global thresholding, and segmentation is presented, which is here applied to different clinical scenarios involving bimodal MR image analysis: uterine fibroid segmentation in MR guided Focused Ultrasound Surgery, and brain metastatic cancer segmentsation in neuro-radiosurgery therapy.

A new approach for medical image enhancement based on luminance-level modulation and gradient modulation

TL;DR: Experimental results on CT images, X-ray images and MRI images from medical image datasets and quantitative analyses by structural similarity index measurement, average gradient, relative enhancement in contrast (REC) and information entropy demonstrate that the results of the proposed LM&GM method are competitive and overwhelm those of the existing methods.

Contrast enhancement using brightness preserving bi-histogram equalization

TL;DR: It is shown mathematically that the proposed algorithm preserves the mean brightness of a given image significantly well compared to typical histogram equalization while enhancing the contrast and, thus, provides a natural enhancement that can be utilized in consumer electronic products.

Contrast enhancement using recursive mean-separate histogram equalization for scalable brightness preservation

TL;DR: Simulation results show that the cases which are not handled well by HE, BBHE and dualistic sub image histogram equalization (DSIHE), have been properly enhanced by RMSHE.
