Image enhancement using background brightness preserving histogram equalisation
Histogram equalisation (HE) is widely used to enhance the image contrast but it tends to over-enhance the image background brightness. Improvement schemes have been introduced to reduce this defect of the conventional HE, but the over-enhancement of the background brightness is still obvious. A...

| description | Histogram equalisation (HE) is widely used to enhance the image contrast
but it tends to over-enhance the image background brightness.
Improvement schemes have been introduced to reduce this defect of
the conventional HE, but the over-enhancement of the background
brightness is still obvious. A novel approach of nonlinear HE is presented,
which is able to enhance the image contrast while preserving
the background brightness for images with well-defined background
brightness. |
