Embodiment Construction

[0074] Below in conjunction with accompanying drawing, the present invention will be further described:

[0075] Such as figure 1 Said, an adaptive image defogging method based on sharpness evaluation, including: image preprocessing, image sharpness judgment, image defogging processing and coding decision optimization;

[0076] The image clarity judgment is to classify the input haze image according to the definition of visibility in meteorology;

[0077] The image defogging process is to sequentially call the defogging algorithm for the classified haze images to process;

[0078] The encoding decision-making optimization is to evaluate the image quality of the processing results, and introduce the encoding decision-making method to the evaluation results, and then adaptively call the dehazing algorithm again for processing, so as to realize the optimization of the output effect.

[0079] Described a kind of adaptive image defogging method based on sharpness evaluation, spec...

Abstract

The invention discloses a self-adaptive image defogging method based on resolution evaluation. The self-adaptive image defogging method comprises the steps of image pretreatment, image resolution judgment, image defogging treatment and coding decision optimization; image resolution judgment comprises the step that input haze images are classified according to the definition of visibility in meteorology; image defogging treatment comprises the step that the classified haze images are processed in sequence by calling a defogging algorithm; coding decision optimization comprises the steps that aprocessing result is subjected to image quality evaluation, a coding decision method is introduced to the evaluation result, accordingly the evaluation result is processed by calling the defogging algorithm in a self-adaptive mode again, and thus optimization of the output result is achieved. The self-adaptive image defogging method solves the problems of low image saturability caused by a Retinexdefogging algorithm, severe detail information loss of defogging images caused by a contrast enhancement method, and low robustness caused by an atmospheric scattering model method. The self-adaptiveimage defogging method is high in universality and stability, and the processed images have good effect and high quality.

Description

technical field [0001] The invention relates to the technical fields of computer vision and image defogging, in particular to an adaptive image defogging method based on definition evaluation. Background technique [0002] With the continuous development and progress of society, especially the continuous entry of science and technology, people's material life has been greatly improved and improved, especially the continuous acceleration of urbanization and the rapid development of the transportation industry, people can go out Learn more about the outside world. The rapid development and progress of society has also brought many negative impacts, such as the destruction of a large number of land vegetation, the serious discharge of industrial polluting enterprises, and the sharp increase in the number of locomotives, which has caused serious damage to the air environment on which people live. [0003] In recent years, with the change of the environment and climate and the c...
