Embodiment

[0053] The content-based image aesthetic quality improvement method of this embodiment includes the following steps:

[0054] S1 image content perception and recognition, the process is as figure 1 Shown:

[0055] S1.1 Collect four categories of image photos from the Internet, namely human faces, buildings, night scenes and other categories of images, each category has 10,000 images, and the images are formed into a training set; the other categories of images The images are images other than human faces, buildings, and night scenes;

[0056] S1.2 Extract the SIFT feature (Scale-invariant feature transform) of each image in the training set, and send it to the multi-class SVM (Support Vector Machine) support vector machine for training, and obtain the four categories of image scores Interface model

[0057] S1.3 Send the image to be adjusted into the interface model of the four major categories of images obtained in step S1.2 to obtain the corresponding category output:

[0058] S2 ad...

Abstract

The present invention discloses a content-based image aesthetic quality improvement method. According to a pre-trained category classifier, images with the need of adjustment are subjected to the image classification of four categories, and the images are face category images, building category images, night scene category images and other types of images. For the four categories of images, the corresponding image aesthetic quality improvement is carried out. The face category images are subjected to face dermabrasion processing. The building category images are subjected to horizontal and vertical plane adjustment processing. The night scene category images are subjected to removing dynamic flur processing. The other types of images are subjected to image adjustment composition processing through image cropping. According to the method, the image aesthetic quality improvement is subjected to adaptive adjustment according to the image content, the algorithm realization is simple, and the method is easily adapted to a mobile terminal with weak computing ability to realize.

Description

Technical field [0001] The present invention relates to the field of artificial intelligence technology, in particular to a method for improving the quality of image aesthetics based on content. Background technique [0002] At present, in terms of image quality evaluation, there are a large number of invention patents disclosed, but in terms of image quality improvement, only individual invention patents are disclosed. Among them, the patent application CN104427347A proposes a method for improving the image quality of a network camera video surveillance system, which relates to a method for improving the image quality of a network camera video surveillance system. The cost threshold is compared to obtain the best candidate motion vector, and the quality of the lost image is improved according to the obtained best candidate motion vector. As a result, the time-domain error concealment data processing weighted by the multi-block mode is realized. At the same time, it is simple a...
