چکیده

In this paper, we introduce a simple but effective method in order to remove haze in foggy images. We name it as dark pixel detection. Dark pixel is the pixel in haze-free images with values in all of the RGB colour channels close to zero. With this method, we can effectively estimate the thickness of the haze and recover a vivid haze-free scene even when the scene object is inherently similar to the air light across a large region. In addition, our algorithm is fast and with good dehazing quality.

Mobile Haze Removal Application

In this paper, we implement a dehazing algorithm using dark pixel detection in MatLab and C++/OpenCV. The algorithm is originally proposed in Yu et al.’s paper. The simplicity and effectiveness of the algorithm make it possible for us to run the C++/OpenCV implementation on Android phones through android NDK with reasonable speed. Keywords—dehaze; image processing; mobile application; computer ...

Fpga Implementation of Haze Removal Algorithm for Image Processing

Haze removal is a difficult problem due the inherent ambiguity between the haze and the underlying scene. All images contain some noise due to sensor error that can be amplified in the haze removal process. A number of methods have been proposed for haze removal. In this paper proposes a simple but effective image prior to remove haze from a single input image. By using single image it removes ...

 A novel approach to automatic position calibration for pixelated crystals in gamma imaging

Introduction: The position estimation in gamma detection system will have constant misplacements which can be corrected in the calibration procedure. In the pixelated crystal uniformly irradiation of detector will produce irregular shape due to position estimation errors. This image is called flood field image and is used to calibrate the position estimation. In this work we pr...
