Single image defogging has received increased attention recently. However, most existing methods are generic restoration methods which may cause partial over-enhancing to the image at a short distance. This certainly makes these defogging methods may be not suitable for road images. In this paper, we propose a new image defogging algorithm that divides the original foggy image into three region...

Automatic image synthesis research has been rapidly growing with deep networks getting more and more expressive. In the last couple of years, we have observed images of digits, indoor scenes, birds, chairs, etc. being automatically generated. The expressive power of image generators have also been enhanced by introducing several forms of conditioning variables such as object names, sentences, b...

Gender classification aims at recognizing a person’s gender. Despite the high accuracy achieved by state-of-the-art methods for this task, there still room for improvement in generalized and unrestricted datasets. In this paper, we advocate a new strategy inspired by the behavior of humans in gender recognition. Instead of dealing with the face image as a sole feature, we rely on the combinatio...

Realistic rendering of sky scene is important in virtual environment. Traditional methods are mostly based on skybox, thus failing to realistically simulate the change of sky scene under different weathers and conditions. In this paper, a new sky light model under different weathers for virtual environment is proposed. We first analyze the atmosphere characters of sky scene, and calculate the l...

The contrast of outdoor images grabbed under adverse weather conditions, especially foggy weather, is altered by the scattering of daylight by atmospheric particles. As a consequence, different methods have been designed to restore the contrast of these images. However, there is a lack of methodology to assess the performances of the methods or to compare them with one another. Unlike image qua...

Moving object detection has been widely used in diverse discipline such as intelligent transportation systems, airport security systems, video monitoring systems, and so on. In this paper, we propose an efficient moving object detection method using enhanced edge localization mechanism and gradient directional masking for video surveillance system. In our proposed method, gradient map images ar...

PERSONS who present ocular hypertension following iritis, traumatism or tumour may have hard eyes and increased intraocular tension without necessarily being glaucomatous. While certain cases of this kind may be benefited by decompressive treatment, it is necessary to distinguish such conditions from true glaucoma and to define the signs of this affection, which illuminate its pathogeny and thu...
