Embodiment Construction

[0019] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0020] This embodiment proposes an image sharpness processing method, including the following steps:

[0021] Step 1: Open the original image to be processed in the image processing software, then analyze the subject type of the original image, determine the emphasis range and threshold value according to the subject type, and use a lower range of clarity for the original image with a larger area of ​​skin Emphasize or use a higher threshold value for sharpness processing, and use higher sharpness emphasis for the original image with more details;

[0022] Step 2: Correct the original image, then obtain the corrected original image format size and resolution parameters, and then sele...

Abstract

The invention discloses an image definition processing method. The method comprises the following steps: determining an emphasis amplitude and a threshold value according to the main body type of an original image; selecting a radius value according to the breadth size and the resolution parameter of the original image; carrying out definition emphasis processing on different color plate channelsincluded in the original image one by one; performing definition processing to obtain a clear image; performing gray scale adjustment on the clear image, then performing layering processing on the clear image, dividing the clear image into a high-frequency image layer and a low-frequency image layer, and performing wavelet transform-based noise reduction processing on the high-frequency image layer and the low-frequency image layer to obtain a new clear image. According to the invention, based on different characteristics and types of images, the emphasis amplitude, radius value and thresholdvalue are reasonably selected, the optimal definition adjustment can be properly performed on the basis of comprehensive balanced use of all functions, the noise reduction processing based on wavelettransform is performed, the targeted noise reduction can be performed, and the integrity of the image information and the definition can be further stably maintained by the new clear image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image definition processing method. Background technique [0002] Image clarity is one of the criteria to measure the quality of images. A clear image can give people a pleasing visual enjoyment. For a long time, image scanning equipment and image processing software developers and manufacturers have attached great importance to the development of image clarity processing functions. , image processing personnel are also constantly exploring the adjustment skills of image clarity in daily practice; [0003] The existing sharpness processing does not start from the characteristics and types of the image itself, and it is impossible to perform targeted sharpness processing for different images, and the sharpness-processed image does not undergo subsequent processing, and the sharpness cannot be further improved. Therefore, the present invention proposes an image definit...
