Problems solved by technology

Existing digital imaging products can only take and save digital photos. To sort and classify digital photos, manual methods are still required.
However, it takes a lot of time and energy to manually recognize the faces in the digital photos taken, and manually sort and classify the digital photos according to the set conditions.

Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] In the embodiment of the present invention, assuming that the resolution of the digital photo is M*N (M, N is an integer), the digital photo can be regarded as a mathematical two-dimensional matrix, wherein the horizontal length of the two-dimensional matrix is ​​M , the vertical length is N, which means that the color information of the pixel corresponding to the coordinate position is 8bit bit width, then each matrix element uses an integer from 0 to 255 to represent the color information, and the horizontal and vertical values ​​of the two-dimensional matrix represent this The position coordinate information of the pixel in the image. By analogy, a picture of any pixel size and any number of colors can be regarded as a mathematical two-dimensional matrix. The digital photos discussed in the following embodim...

Abstract

The invention relates to a digital photo sorting method, a device and an application system thereof. The method comprises the following steps: acquiring target face data contained in the stored digital photos and reference face data; acquiring the biological feature parameters of the reference face data and the target face data; calculating the similarity value of the biological feature parameters of the reference face data and the target face data; and finally comparing the similarity value with a set similarity threshold, and then selecting out the target face data as the same as the reference face data according to setting conditions. In the invention, by calculating the similarity value of the biological feature parameters of the reference face data and the target face data and selecting out the target face data as the same as the reference face data according to the setting conditions, the digital photo sorting method, the device and the application system thereof can automatically sort and classify the digital photos shot by a digital imaging product, and save time and energy of a user.

Description

technical field [0001] The invention relates to image recognition technology, in particular to a digital photo sorting method, device and application system. Background technique [0002] With the rapid development of digital imaging technology, a large number of digital photos have been taken. In practical applications, it is sometimes necessary to select photos containing images of a certain person or several people from multiple photos. For example: the total N digital photos taken by A, B, C, and D are classified and selected, and among the digital photos taken, including L single photos containing A and M photos of A and others ( L+M<=N, L, M, and N are all positive integers) are selected. Existing digital imaging products can only take and save digital photos, and it is still necessary to use manual methods to sort and classify digital photos. However, it takes a lot of time and energy to manually identify the faces in the digital photos taken, and manually sort ...
