Embodiment

[0055] Such as figure 1Shown, the photo classification method of the present invention comprises the following steps:

[0056] S1 training process:

[0057] S1.1 Collect sample photos for training:

[0058] Download photos from the professional photography website flickr, and divide these photos into ten categories according to the content, namely animals, plants, people, static, architecture, landscape, night scene, rain scene, machinery and city; and according to the clarity and aesthetics Divide photos into positive and negative samples;

[0059] S1.2 Extracting the subject area of ​​the sample photo;

[0060] The subject area extraction specifically includes the following steps:

[0061] S1.2.1 Convert photos from RGB color space to grayscale color space, the calculation formula is as follows:

[0062] Y=0.2989R+0.5870G+0.1140B

[0063] Where Y represents the gray value, and R, G, and B are the channel values ​​of the color image of the current pixel;

[0064] S1.2....

Abstract

The invention discloses a photo classification method. The photo classification method comprises a training process and an automatic classification process, wherein the training process comprises the following steps: extracting a subject area of a sample photo through a method based on power spectrum inclination; extracting characteristics of the sample photo; and training aesthetic quality of the photo through an SVM (support vector machine) classifier to obtain an interface model; the automatic classification process comprises the following steps: extracting the subject area of the photo to be recognized through the method based on the power spectrum inclination, extracting the characteristics, and recognizing by the interface model. By the photo classification method, aesthetics is taken as a standard of automatic classification, and accuracy rate is high.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a photo classification method. Background technique [0002] At present, there are many technologies and patent inventions for automatic management and archiving of photos and image quality evaluation. For example, the application number is CN200910130984.4. When a photo is taken, it is used to analyze the composition of the photo to obtain the characteristics of the composition of the photo, and the calculation is ideal. eigenvalues, real eigenvalues, and differences between said ideal features and said real eigenvalues, and generating grades based on said differences to show the quality associated with the composition of said photographs, in order to evaluate the captured photographs guide. The invention with application number CN200810305013.4 provides a photo management method, which is used for photo management of electronic devices. First, the system detect...
