Dynamic contrast enhancement and flexible odor codes

Dynamic contrast enhancement and flexible odor codes

Sensory stimuli evoke spiking activities patterned across neurons and time that are hypothesized to encode information about their identity. Since the same stimulus can be encountered in a multitude of ways, how stable or flexible are these stimulus-evoked responses? Here, we examined this issue in the locust olfactory system. In the antennal lobe, we found that both spatial and temporal featur...

Dynamic Contrast Enhancement Algorithm

This article describes a dynamic contrast enhancement technique to improve the visual quality of low contrast images. Also, this proposed algorithm is recovered the images from a blurred and darkness specimen of the given area of the images, and get better quality of the images. In this article, Image enhancement is performed using evolutionary algorithm (i.e. Genetic Algorithm). Here, a specia...

Dynamic Contrast Enhancement Using Multiple and Clipped Histogram Equalization

Histogram equalization (HE) is one of the common methods for improving contrast in digital images. However, HE may introduce some unnecessary visual deterioration while enhancing image. One of the solutions to overcome this weakness is by preserving the mean brightness of the output image. This paper proposes a new method, known as dynamic contrast enhancement using multiple and clipped histogr...

Contrast Enhancement and Foreground Image Sharpening using Dynamic Stochastic Resonance

In this paper we enhanced poor illuminated low contrast image and sharpen the foreground part using stochastic resonance (SR). Noise generally hinders communication system. But by using SR image, performance is improved by adding noise. At an optimum noise level SNR performance become appreciable. Literally this pixel dynamics concepts adopts particle mechanics following Benzi’sbistable model. ...
