Fast Single-image Defogging
Bad weather conditions such as fog, haze, and dust often reduce the performance of outdoor cameras. To improve the effectiveness of surveillance and in-vehicle cameras under such conditions, we propose a method based on a dark channel prior for quickly defogging images. It first estimates the intensity of the atmospheric light by searching the sky area in the foggy image. Then it estimates the ...
متن کاملSingle Image Defogging Algorithm based on Dark Channel Priority
Based on dark channel priority, the paper proposes an improved defogging algorithm of single image which can defog the foggy images rapidly. The algorithm in the paper applies the method combining adaptive median filter and bilateral filter to figure out clear dark channel on the edge. And the algorithm is based on the physical model of foggy images to estimate transmission. Compared with the t...
متن کاملImage Defogging Algorithm of Single Color Image Based on Wavelet Transform and Histogram Equalization
Because of light scattered by the suspended particles in the atmosphere, photographs taken in the foggy day look gray and lack of visibility. In order to unveil the clear image’s structures and colors, we propose a image defogging algorithm of single color image based on wavelet transform and histogram equalization. Firstly, using histogram equalization to enhancement image, then to nonlinear e...
متن کاملIncident Light Frequency-based Image Defogging Algorithm
Considering the problem of color distortion caused by the defogging algorithm based on dark channel prior, an improved algorithm was proposed to calculate the transmittance of all channels respectively. First, incident light frequency’s effect on the transmittance of various color channels was analyzed according to the Beer-Lambert’s Law, from which a proportion among various channel transmitta...
متن کاملSingle Image Defogging Method Using Variational Approach for Edge-Preserving Regularization
Abstract—In this paper, we propose the variational approach to solve single image defogging problem. In the inference process of the atmospheric veil, we defined new functional for atmospheric veil that satisfy edge-preserving regularization property. By using the fundamental lemma of calculus of variations, we derive the EulerLagrange equation foratmospheric veil that can find the maxima of a ...
