Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] The present invention provides a method for automatic detection of image blurred areas, referring to figure 1 , in the first embodiment, the automatic detection method of the blurred image area includes:

[0052] Step S10, extracting clear image samples and blurred image samples from a preset image database;

[0053]Step S20, using the clear image samples, blur image samples and preset network structure to train the parameters of the deep convolutional neural network model to obtain network models of clear image samples and blur image samples;

[0054] In the present invention, a certain number of images can be prepared in advance, and the images contain at least some clear areas, and these images can be obtained from many open-source image databases. For each image in the image library, a certain amount of r...

Abstract

The invention discloses an image fuzzy region automatic detection method and system. The method comprises the following steps of extracting a clear image sample and a fuzzy image sample from a preset image database, training parameters of a deep convolutional neural network model by utilizing the clear image sample, the fuzzy image sample and a preset network structure, and obtaining network models of the clear image sample and the fuzzy image sample; inputting all small image blocks to the trained model, and performing prediction of the deep convolutional neural network models of the small image blocks in sequence according to the same model structures and the trained parameters, until clear confidence degrees and fuzzy confidence degrees of all the small image blocks are finally obtained; and performing operation on the clear confidence degrees and the fuzzy confidence degrees of all the small image blocks to obtain a definition score of a whole image. According to the method and the system, the time and economic costs of manual tagging can be reduced, the automation degree can be improved, and the network performance can be ensured.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic detection method and system for image blurred areas. Background technique [0002] Clarity is an evaluation index that is crucial to measure image quality. For image users or producers, it is expected to use or produce images with clear subjects to express the meaning they want to convey. For example, for image producers, when users take photos or videos, although the current focusing technology and anti-shake technology can help users improve the quality of images to a certain extent, these technologies cannot guarantee that all captured images and videos are perfect. clear. Due to the failure of focusing, the strong movement of the object being photographed, or the hand shake of the photographer during the shooting process, the user may obtain blurred photos or videos without knowing it, and lose the opportunity to re-shoot. If there is a technology for ...
