| Abstract | ||
| In this paper, we present a new image enhancement algorithm which is apply to enhance night images or very low luminance images by using Gaussian convolution and adaptive dynamic range compression of intensity that is dependent on non leaner function. This leads a robust algorithm is more resilience and that with low parameter moreover it's improve dark region in digital image by luminance and contrast enhancement called non leaner adaptive NLA filter . The results was compared with Histogram Equalization HE and multi scale retinex MSR algorithm by calculate normalize mean square error NMSR between processed images and original images with fair lightness, histogram of all method enhancement is a account . Adaptive filter has high efficiency in enhanced night image with low lightness compared with other methods. | ||
