Contrast enhancement of an image can be performed by using a simple histogram equalisation (HE) technique. However, there are some drawbacks of HE like immense brightness change, artificial effects, over-enhancement, which make it unsuitable to be us

An adaptive geometric filter approach based on average brightness of the image and discrete cosine transform (DCT) coefficient adjustment is proposed in this paper for gray and color image enhancement. Adaptive geometric filter is employed for smooth

Most of the adaptive histogram equalization methods enhanced the image locally instead of global enhancement. In this paper, a global enhancement method is proposed which is based on modified probability density function and expected value of image i

Contrast magnification is a critical parameter of image enhancement. Remote sensing images are distance captured images, so they naturally have very low contrast as compared to other images. In this paper a very simple and efficient technique based o

Contrast enhancement and Mean brightness conservation are two important parameters of image enhancement. A high contrast image is good in subjective quality assessment but also high contrast may cause over or under enhancement in the enhanced image.

Mean brightness conservation and enhancement of contrast are two important parameters of image enhancement. A high contrast image is good in subjective quality assessment. Entropy of an image represents the image contrast. Contrast can be well enhanc

Histogram equalization is the simplest method of image enhancement. Mean brightness and contrast are important parameters of an image. Artifacts are generated if the original mean brightness of an image is not preserved. A high contrast provides good
