Recent years have witnessed the increasing popularity of learning based methods to
enhance the color and tone of photos. However, many existing photo enhancement methods …

Underwater images suffer from blurring effects, low contrast, and grayed out colors due to
the absorption and scattering effects under the water. Many image enhancement algorithms …

This paper proposes an algorithm that enhances the contrast of an input image using
interpixel contextual information. The algorithm uses a 2-D histogram of the input image …

To improve contrast and restore color for underwater images without suffering from
insufficient details and color cast, this paper proposes a fusion algorithm for different color …

This paper proposes a novel algorithm, which enhances the contrast of an input image using
spatial information of pixels. The algorithm introduces a new method to compute the spatial …

In this paper, we propose an adaptive image equalization algorithm that automatically
enhances the contrast in an input image. The algorithm uses the Gaussian mixture model to …

The rapid growth of digital libraries, e-governance, and internet based applications has
caused an exponential escalation in the volume of 'Big-data'particularly due to texts, images …

In this paper, we propose a two-dimensional histogram equalization (2DHE) algorithm which
utilizes contextual information around each pixel to enhance the contrast of an input image …

As an efficient image contrast enhancement (CE) tool, adaptive gamma correction (AGC)
was previously proposed by relating gamma parameter with cumulative distribution function …

We study the problem of automatically correcting the exposure of an input image. Generic
auto-exposure correction methods usually fail in individual over-/under-exposed regions …
