Improved image defogging method and its application in video monitoring system based on ARM

Improved image defogging method and its application in video monitoring system based on ARM Purpose – The purpose of this paper is to improve an image defogging algorithm based on a dark channel prior and use this method to clear the foggy image on the Advanced RISC (Reduced Instruction Set Computing) Machines (ARM) platform. Design/methodology/approach – The divided strategy of the foggy image was proposed through the estimation of the brightness and transmission thresholds. The two regions of the foggy image were processed using two transmissions. Many foggy images were tested using the improved method. Findings – The finding resulting from this study is that a divided strategy has been proposed to use the image defogging. Compared with the existing methods, the running time of the improved method is less on the ARM platform. Practical implications – Image enhancement is an important technology of digital images, and the quality of images plays a key role in the video monitoring and the intelligent transportation system. Originality/value – This paper presented an improved image defogging method using the divided strategy and a substantial number of experimental results was provided to demonstrate this method. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Sensor Review Emerald Publishing

Abstract

Purpose – The purpose of this paper is to improve an image defogging algorithm based on a dark channel prior and use this method to clear the foggy image on the Advanced RISC (Reduced Instruction Set Computing) Machines (ARM) platform. Design/methodology/approach – The divided strategy of the foggy image was proposed through the estimation of the brightness and transmission thresholds. The two regions of the foggy image were processed using two transmissions. Many foggy images were tested using the improved method. Findings – The finding resulting from this study is that a divided strategy has been proposed to use the image defogging. Compared with the existing methods, the running time of the improved method is less on the ARM platform. Practical implications – Image enhancement is an important technology of digital images, and the quality of images plays a key role in the video monitoring and the intelligent transportation system. Originality/value – This paper presented an improved image defogging method using the divided strategy and a substantial number of experimental results was provided to demonstrate this method.
